Hi,

I'm using freeswitch 1.15 in Freebsd 10.1, with mod_gsmopen

FreeSWITCH Version 1.5.15b+git~20150407T231134Z~d55c4a053b~64bit (git d55c4a0 2015-04-07 23:11:34Z 64bit), whats happen, its the same with another versions like, 1.6, 1.4.19, etc

After sometime running freeswitch, i have this TTYs.

crw------- 1 root wheel 0x8e Sep 24 15:30 ttyU1.3 crw------- 1 root wheel 0x8f Sep 24 15:30 ttyU1.3.init crw------- 1 root wheel 0x90 Sep 24 15:30 ttyU1.3.lock crw------- 1 root wheel 0x8e Sep 24 15:30 ttyU2.3 crw------- 1 root wheel 0x8f Sep 24 15:30 ttyU2.3.init crw------- 1 root wheel 0x90 Sep 24 15:30 ttyU2.3.lock crw------- 1 root wheel 0x8e Sep 24 15:30 ttyU3.3 crw------- 1 root wheel 0x8f Sep 24 15:30 ttyU3.3.init crw------- 1 root wheel 0x90 Sep 24 15:30 ttyU3.3.lock crw------- 1 root wheel 0x76 Sep 25 00:46 ttyU4.0 crw------- 1 root wheel 0x77 Sep 24 22:28 ttyU4.0.init crw------- 1 root wheel 0x78 Sep 24 22:28 ttyU4.0.lock crw------- 1 root wheel 0x7c Sep 24 22:28 ttyU4.1 crw------- 1 root wheel 0x7d Sep 24 22:28 ttyU4.1.init crw------- 1 root wheel 0x7e Sep 24 22:28 ttyU4.1.lock crw------- 1 root wheel 0x82 Sep 24 22:28 ttyU4.2 crw------- 1 root wheel 0x83 Sep 24 22:28 ttyU4.2.init crw------- 1 root wheel 0x84 Sep 24 22:28 ttyU4.2.lock crw------- 1 root wheel 0x8e Sep 24 22:28 ttyU4.3 crw------- 1 root wheel 0x8f Sep 24 22:28 ttyU4.3.init crw------- 1 root wheel 0x90 Sep 24 22:28 ttyU4.3.lock crw------- 1 root wheel 0xa8 Sep 25 00:46 ttyU5.0 crw------- 1 root wheel 0xa9 Sep 24 22:28 ttyU5.0.init crw------- 1 root wheel 0xaa Sep 24 22:28 ttyU5.0.lock crw------- 1 root wheel 0xae Sep 24 22:28 ttyU5.1 crw------- 1 root wheel 0xaf Sep 24 22:28 ttyU5.1.init crw------- 1 root wheel 0xb6 Sep 24 22:28 ttyU5.1.lock crw------- 1 root wheel 0xba Sep 24 22:28 ttyU5.2 crw------- 1 root wheel 0xbb Sep 24 22:28 ttyU5.2.init crw------- 1 root wheel 0xbc Sep 24 22:28 ttyU5.2.lock crw------- 1 root wheel 0xc0 Sep 24 22:28 ttyU5.3 crw------- 1 root wheel 0xc1 Sep 24 22:28 ttyU5.3.init crw------- 1 root wheel 0xc2 Sep 24 22:28 ttyU5.3.lock

As you can see, ttyU1.3, ttyU2.3, ttyU3.3 are USB deadlocks

I try to unload mod_gsmopen, but i receive a message that is in use so i kill freeswitch, then ttyU1.3, ttyU2.3, ttyU3.3, are free and disappear (as well .init and .lock)

I try to figure out whats happening, with logs, alarms, but i can't. Someone have the same problem, or know the solution?

ps. Reading the list, i realize that few members use the module, or don't have problems. If i am correct, is there any other way to use GSM modems or GSM, which is low cost? Is there anyone who can guide me in some things about the code or tips?

ps 2. sorry about my english

I can't use Debian, because our system depends of FreeBSD, and we have a lot of source (daemons) running, based, on that platform. And we use kqueue, I think Debian don't have kqueue, it's like epool, but better, much better.

Anyway, I don't That it's a kernel problem, because, since I have another daemon, attached in ttyx.0 (mod_gsmopen attach to ttyx.3), and when modem power off or "reset", only ttyx.3 still locked.

I'm trying to read the source to figure what's happening, but it's hard to read, not because the source is difficult, but because isn't organized.

I'm thinking in rewrite the module, but if in future someone change something in original module I will need to check my source. There is another thing, I don't know how things like apr_thread works, and what functions like switch_sleep(1000000) do and why using that.

Today I make some alterations where the module make a lock, LOKKA, there is some functions who don't have unlock, and another who only have unlock, sometimes two unlocks. So I will wait to see what will happen.

Now, here it's 3:00 am, and I'm going to sleep, almost 19 hours awake up, trying to debug this module and another things.

Maybe you or someone have a time, to chat, or reply some e-mails, or maybe here, to explain some questions about the source (module)?

There's some lines marked with TODO, why? And there is another version of this module? Which the maximum number of modems that you already usage?

Now, i make some changes, and until now it's running fine I think the problem was when you declare interface as dead, like line 674 of gsmopen_protocol.cpp https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/mod/end... alarm_event(tech_pvt, ALARM_FAILED_INTERFACE, "gsmopen_serial_monitor failed, declaring interface dead"); tech_pvt->active = 0; ->>>> tech_pvt->name[0] = '\0'; You make a \0 in interface name So, when someone call remove_interface() in mod_gsmopen.cpp https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/mod/end... To grab the tech_pvt, the function check for strlen or compare GSMOPEN_INTERFACES[interface_id].name (line 322 and 329) Then, we will not found interface (tech_pvt), because "name" is nothing continuing, in line 336 it's check if there is a tech_pvt if (!tech_pvt) { DEBUGA_GSMOPEN("interface '%s' does not exist\n", GSMOPEN_P_LOG, the_interface); goto end; } This check will jump the Close in line 385, causing a deadlock opened fd. res = tech_pvt->serialPort_serial_control->Close(); So i comment every line when you set tech_pvt->name[0] = '\0'; It's correct? Since when interface failed, and it's declared as died, the serial isn't closed, just marked as died, and the tty still opened causing a deadlock, if no one close this. 2015-09-25 14:10 GMT-04:00 Luiz Fernando Softov <fernando@softov.com.br>:

I make a daemon, witch manage USB using kqueue and other things, so, every time i plug or unplug a modem, i make a event, like ARRIVE and LEAVE.

This daemon have a list of modems, correlate with ttys ids - U3G (U0.0, U0.1, U0.2) and UMODEM (U0 U1 U2)

So, when a modem ARRIVE, and it's "attached" (configured), i call a "gsm reload". When a modem LEAVE, i call a gsm remove interface_x.

Using mod_xml_curl, i have dynamic config.

I use events, like gsmopen_dump list, to manage and controll interfaces, like when user "detach" a modem.

If you want, send me a e-mail, i will give access to my system and you can see what i'm talking about.

Anyway, i found things like in function

int gsmopen_serial_write_AT_noack(private_t *tech_pvt, const char *data)

// You make LOKKA(tech_pvt->controldev_lock);

Then call gsmopen_serial_write_AT(tech_pvt, data), and inside gsmopen_serial_write_AT, when something is wrong, you make UNLOCKA(tech_pvt->controldev_lock); and return -1

But, you check if (gsmopen_serial_write_AT(tech_pvt, data) != (int) strlen(data)) {

Then, you make again UNLOCKA(tech_pvt->controldev_lock);

Why make two times UNLOCKA(tech_pvt->controldev_lock); ?

It's like LOKKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock);

Another is in int gsmopen_serial_read_AT(private_t *tech_pvt, int look_for_ack, int timeout_usec, int timeout_sec, const char *expected_string, int expect_crlf) You make a LOKKA(tech_pvt->controldev_lock);, but there is some returns (inside try catch), without UNLOCKA.

Sorry if i make some mistakes in my explanation, but i just want to undestand how this funcions works.

I disagree with "Shaabir" about this module is not useable. I just think this need some changes to work fine. I already test this module with 40 modems for 7 days, and it's work fine, until i grab a deadlock in USB.

Giovanni, if you have time to chat with me, i will be grateful.

Now, i make some changes, and until now it's running fine

I think the problem was when you declare interface as dead, like line 674 of gsmopen_protocol.cpp

https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/mod/end...

alarm_event(tech_pvt, ALARM_FAILED_INTERFACE, "gsmopen_serial_monitor failed, declaring interface dead"); tech_pvt->active = 0; ->>>> tech_pvt->name[0] = '\0';

You make a \0 in interface name

So, when someone call remove_interface() in mod_gsmopen.cpp

https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/mod/end...

To grab the tech_pvt, the function check for strlen or compare GSMOPEN_INTERFACES[interface_id].name (line 322 and 329)

Then, we will not found interface (tech_pvt), because "name" is nothing

continuing, in line 336 it's check if there is a tech_pvt

...

if (!tech_pvt) { DEBUGA_GSMOPEN("interface '%s' does not exist\n", GSMOPEN_P_LOG, the_interface); goto end; }

This check will jump the Close in line 385, causing a deadlock opened fd. res = tech_pvt->serialPort_serial_control->Close();

So i comment every line when you set tech_pvt->name[0] = '\0';

It's correct? Since when interface failed, and it's declared as died, the serial isn't closed, just marked as died, and the tty still opened causing a deadlock, if no one close this.

your reasoning seems sound, is the system still running ok?

Have you changed anything else?

Can you send me (to my mail, as an attach) a git diff? Or open a jira attaching that diff?

Btw, yes, I'm interested in understanding better how your system works (daemon, attach-detach, and all).

Also, big thanks for taking the time to look into the source code!!!

I make a daemon, witch manage USB using kqueue and other things, so, every time i plug or unplug a modem, i make a event, like ARRIVE and LEAVE.

This daemon have a list of modems, correlate with ttys ids - U3G (U0.0, U0.1, U0.2) and UMODEM (U0 U1 U2)

So, when a modem ARRIVE, and it's "attached" (configured), i call a "gsm reload". When a modem LEAVE, i call a gsm remove interface_x.

Using mod_xml_curl, i have dynamic config.

I use events, like gsmopen_dump list, to manage and controll interfaces, like when user "detach" a modem.

If you want, send me a e-mail, i will give access to my system and you can see what i'm talking about.

Anyway, i found things like in function

int gsmopen_serial_write_AT_noack(private_t *tech_pvt, const char *data)

// You make LOKKA(tech_pvt->controldev_lock);

Then call gsmopen_serial_write_AT(tech_pvt, data), and inside gsmopen_serial_write_AT, when something is wrong, you make UNLOCKA(tech_pvt->controldev_lock); and return -1

But, you check if (gsmopen_serial_write_AT(tech_pvt, data) != (int) strlen(data)) {

Then, you make again UNLOCKA(tech_pvt->controldev_lock);

Why make two times UNLOCKA(tech_pvt->controldev_lock); ?

It's like LOKKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock);

Another is in int gsmopen_serial_read_AT(private_t *tech_pvt, int look_for_ack, int timeout_usec, int timeout_sec, const char *expected_string, int expect_crlf) You make a LOKKA(tech_pvt->controldev_lock);, but there is some returns (inside try catch), without UNLOCKA.

Sorry if i make some mistakes in my explanation, but i just want to undestand how this funcions works.

I disagree with "Shaabir" about this module is not useable. I just think this need some changes to work fine. I already test this module with 40 modems for 7 days, and it's work fine, until i grab a deadlock in USB.

Giovanni, if you have time to chat with me, i will be grateful.

2015-09-25 12:41 GMT-04:00 Giovanni Maruzzelli <gmaruzz@gmail.com>:

...

for plugging and unplugging modems, that's a very difficult thing to manage, this is the best I can come out with (and probably does not work in freebsd):

http://wiki.freeswitch.org/wiki/GSMopen#IMEI_and_IMSI_automatic_device_disco...

you're welcome to find a similar mechanism, and file a jira with a pull request, so it will be inserted in manline.

If your modifications only apply to freebsd, please use #ifdefs, so it still continue to compile and work in Linux.

I'm using a USB with power supply.

But sometimes it's just happen. Sometimes user remove and plug modem again.

I can't use Debian, because our system depends of FreeBSD, and we have a lot of source (daemons) running, based, on that platform. And we use kqueue, I think Debian don't have kqueue, it's like epool, but better, much better.

Anyway, I don't That it's a kernel problem, because, since I have another daemon, attached in ttyx.0 (mod_gsmopen attach to ttyx.3), and when modem power off or "reset", only ttyx.3 still locked.

I'm trying to read the source to figure what's happening, but it's hard to read, not because the source is difficult, but because isn't organized.

I'm thinking in rewrite the module, but if in future someone change something in original module I will need to check my source. There is another thing, I don't know how things like apr_thread works, and what functions like switch_sleep(1000000) do and why using that.

Today I make some alterations where the module make a lock, LOKKA, there is some functions who don't have unlock, and another who only have unlock, sometimes two unlocks. So I will wait to see what will happen.

Now, here it's 3:00 am, and I'm going to sleep, almost 19 hours awake up, trying to debug this module and another things.

Maybe you or someone have a time, to chat, or reply some e-mails, or maybe here, to explain some questions about the source (module)?

There's some lines marked with TODO, why? And there is another version of this module? Which the maximum number of modems that you already usage?

2015-09-25 7:53 GMT-04:00 Giovanni Maruzzelli <gmaruzz@gmail.com>:

if you found problems, please open a jira issue, with all info to replicate the problem, as explained in gsmopen page.

It would be useful for us developers, and to me personally, being the person in charge of gsmopen.

Thanks in advance,

Then call gsmopen_serial_write_AT(tech_pvt, data), and inside gsmopen_serial_write_AT, when something is wrong, you make UNLOCKA(tech_pvt->controldev_lock); and return -1

But, you check if (gsmopen_serial_write_AT(tech_pvt, data) != (int) strlen(data)) {

Then, you make again UNLOCKA(tech_pvt->controldev_lock);

Why make two times UNLOCKA(tech_pvt->controldev_lock); ?

It's like LOKKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock);

Another is in int gsmopen_serial_read_AT(private_t *tech_pvt, int look_for_ack, int timeout_usec, int timeout_sec, const char *expected_string, int expect_crlf) You make a LOKKA(tech_pvt->controldev_lock);, but there is some returns (inside try catch), without UNLOCKA.

Sorry if i make some mistakes in my explanation, but i just want to undestand how this funcions works.

I disagree with "Shaabir" about this module is not useable. I just think this need some changes to work fine. I already test this module with 40 modems for 7 days, and it's work fine, until i grab a deadlock in USB.

Giovanni, if you have time to chat with me, i will be grateful.

...

for plugging and unplugging modems, that's a very difficult thing to manage, this is the best I can come out with (and probably does not work in freebsd):

http://wiki.freeswitch.org/wiki/GSMopen#IMEI_and_IMSI_automatic_device_disco...

you're welcome to find a similar mechanism, and file a jira with a pull request, so it will be inserted in manline.

If your modifications only apply to freebsd, please use #ifdefs, so it still continue to compile and work in Linux.

My bad, i looked better and see that you have made a discovery function. How many modems are you using? How many calls simultaneous? It's working fine? no calls stuck after you unplug/plug modem? I have found errors in source (master). And have made a lot a tests, like: unplug a modem in a middle of call - try to make a call with a modem that no support voice - send a sms at the same time you made a call - receive a call from modem A and route to modem B There is more tests that i have made, and made changes to correct it. Anyway, since i use xml_curl to grab the attached modems, and some modems can be removed/dettached or just have failure of power supply i reload/dettached/remove in according with the system/user interaction. And, that find_ttyusb_devices, don't work in FreeBSD, witch is the SO that i use *i can't user another system, i have made a lot of modifications in kernel and have a complete custom system based on that called BrbOS, with kernel encryption, custom drivers and other things. I make the control of calls using event_socket, and make custom routes according with the time, cost, user, configuration, usage, portability, destination... I need the system working that way, receive events when a modem cannot make calls, and control the modem to reload/attach when i need. So, because of it i create a daemon that i can control and know when a modem changes. I have found, in freeBSD and debian, a commom problem Its like, when i start the system for the first time Lets consider this ModemA (MA) - (ttyU0, ttyU1, ttyU2, ttyU3) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13) MA was unplugged/have power supply problem ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13) MC was unplugged/have power supply problem ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - ModemD (MD) - (ttyU11, ttyU12, ttyU13) MC was plugged/redicovered ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13) MA was plugged/redicovered ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13) As you see, sometimes the modems don't get the tty sequence 1.2.3.4. They get the sequence of free tty ports And, it's just in this test, when i have modems with 4/3 ttys Sometimes, the modem just RESET, and the tty was not free yet, so the modem jump a number in sequence MD was unplugged/have power supply problem ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - MD was on, but ttyU12 still oppened by FreeSwitch (mod_gsmopen) ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU13, ttyU14) As you see, the discovery will not work sometimes, you need to change to get all ttyports not getting as (ttyFOUND + 1) and (ttyFOUND + 2) And, like i said before, if you wan't to made changes i'm able to help or to rewrite the module, just need someone to help If you wan't, send me a e-mail or just reply here 2015-12-08 9:09 GMT-03:00 Shabbir abbasi <shabbirabbasi92@gmail.com>:

Hi: i have made patch for auto reconnect if dongle disconnected and display status of dongle connected or disconnected https://freeswitch.org/jira/browse/FS-8626

i think after this patch you dont need a seprate daemon to run thank u

Now, i make some changes, and until now it's running fine

I think the problem was when you declare interface as dead, like line 674 of gsmopen_protocol.cpp

https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/mod/end...

alarm_event(tech_pvt, ALARM_FAILED_INTERFACE, "gsmopen_serial_monitor failed, declaring interface dead"); tech_pvt->active = 0; ->>>> tech_pvt->name[0] = '\0';

You make a \0 in interface name

So, when someone call remove_interface() in mod_gsmopen.cpp

https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/mod/end...

To grab the tech_pvt, the function check for strlen or compare GSMOPEN_INTERFACES[interface_id].name (line 322 and 329)

Then, we will not found interface (tech_pvt), because "name" is nothing

continuing, in line 336 it's check if there is a tech_pvt

...

if (!tech_pvt) { DEBUGA_GSMOPEN("interface '%s' does not exist\n", GSMOPEN_P_LOG, the_interface); goto end; }

This check will jump the Close in line 385, causing a deadlock opened fd. res = tech_pvt->serialPort_serial_control->Close();

So i comment every line when you set tech_pvt->name[0] = '\0';

It's correct? Since when interface failed, and it's declared as died, the serial isn't closed, just marked as died, and the tty still opened causing a deadlock, if no one close this.

your reasoning seems sound, is the system still running ok?

Have you changed anything else?

Can you send me (to my mail, as an attach) a git diff? Or open a jira attaching that diff?

Btw, yes, I'm interested in understanding better how your system works (daemon, attach-detach, and all).

Also, big thanks for taking the time to look into the source code!!!

I make a daemon, witch manage USB using kqueue and other things, so, every time i plug or unplug a modem, i make a event, like ARRIVE and LEAVE.

This daemon have a list of modems, correlate with ttys ids - U3G (U0.0, U0.1, U0.2) and UMODEM (U0 U1 U2)

So, when a modem ARRIVE, and it's "attached" (configured), i call a "gsm reload". When a modem LEAVE, i call a gsm remove interface_x.

Using mod_xml_curl, i have dynamic config.

I use events, like gsmopen_dump list, to manage and controll interfaces, like when user "detach" a modem.

If you want, send me a e-mail, i will give access to my system and you can see what i'm talking about.

Anyway, i found things like in function

int gsmopen_serial_write_AT_noack(private_t *tech_pvt, const char *data)

// You make LOKKA(tech_pvt->controldev_lock);

Then call gsmopen_serial_write_AT(tech_pvt, data), and inside gsmopen_serial_write_AT, when something is wrong, you make UNLOCKA(tech_pvt->controldev_lock); and return -1

But, you check if (gsmopen_serial_write_AT(tech_pvt, data) != (int) strlen(data)) {

Then, you make again UNLOCKA(tech_pvt->controldev_lock);

Why make two times UNLOCKA(tech_pvt->controldev_lock); ?

It's like LOKKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock); UNLOCKA(tech_pvt->controldev_lock);

Another is in int gsmopen_serial_read_AT(private_t *tech_pvt, int look_for_ack, int timeout_usec, int timeout_sec, const char *expected_string, int expect_crlf) You make a LOKKA(tech_pvt->controldev_lock);, but there is some returns (inside try catch), without UNLOCKA.

Sorry if i make some mistakes in my explanation, but i just want to undestand how this funcions works.

I disagree with "Shaabir" about this module is not useable. I just think this need some changes to work fine. I already test this module with 40 modems for 7 days, and it's work fine, until i grab a deadlock in USB.

Giovanni, if you have time to chat with me, i will be grateful.

"It's working fine? no calls stuck after you unplug/plug modem? " Yes it is working fine ; i have set gsmopen_serial_sync_period=1 in gsmopen.conf due to this if i unplug modem then it is marked as disconnected and hangsup the call and after this discovery thread wakes up and try to find device after every 30 second if device found then it starts serial monitor thread and exits and it is not effects on other modems i have tried many times to unplug modem during calls and after calls but they discovered fine here, On Wed, Dec 16, 2015 at 9:14 AM, Shabbir abbasi <shabbirabbasi92@gmail.com> wrote:

"How many modems are you using?" i am just playing with it with only two modems,i am not a Developer just trying to learn, i am using centos 7 64 bit, my system is not in production , just for experimental, and Discovery function in centos working fine

My bad, i looked better and see that you have made a discovery function.

How many modems are you using? How many calls simultaneous? It's working fine? no calls stuck after you unplug/plug modem?

I have found errors in source (master). And have made a lot a tests, like: unplug a modem in a middle of call - try to make a call with a modem that no support voice - send a sms at the same time you made a call - receive a call from modem A and route to modem B

There is more tests that i have made, and made changes to correct it.

Anyway, since i use xml_curl to grab the attached modems, and some modems can be removed/dettached or just have failure of power supply i reload/dettached/remove in according with the system/user interaction.

And, that find_ttyusb_devices, don't work in FreeBSD, witch is the SO that i use *i can't user another system, i have made a lot of modifications in kernel and have a complete custom system based on that called BrbOS, with kernel encryption, custom drivers and other things.

I make the control of calls using event_socket, and make custom routes according with the time, cost, user, configuration, usage, portability, destination...

I need the system working that way, receive events when a modem cannot make calls, and control the modem to reload/attach when i need. So, because of it i create a daemon that i can control and know when a modem changes.

I have found, in freeBSD and debian, a commom problem

Its like, when i start the system for the first time

Lets consider this ModemA (MA) - (ttyU0, ttyU1, ttyU2, ttyU3) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MA was unplugged/have power supply problem

ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MC was unplugged/have power supply problem

ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MC was plugged/redicovered

ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MA was plugged/redicovered

ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

As you see, sometimes the modems don't get the tty sequence 1.2.3.4. They get the sequence of free tty ports And, it's just in this test, when i have modems with 4/3 ttys Sometimes, the modem just RESET, and the tty was not free yet, so the modem jump a number in sequence

MD was unplugged/have power supply problem

ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) -

MD was on, but ttyU12 still oppened by FreeSwitch (mod_gsmopen)

ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU13, ttyU14)

As you see, the discovery will not work sometimes, you need to change to get all ttyports not getting as (ttyFOUND + 1) and (ttyFOUND + 2)

And, like i said before, if you wan't to made changes i'm able to help or to rewrite the module, just need someone to help If you wan't, send me a e-mail or just reply here

Hi: i have made patch for auto reconnect if dongle disconnected and display status of dongle connected or disconnected https://freeswitch.org/jira/browse/FS-8626

i think after this patch you dont need a seprate daemon to run thank u

Hi, i sent a e-mail to you, with the diff, files and give you access to web interface of the system.

I will wait you to read, confirm and reply my e-mail.

Thanks a lot for the help.

Have you changed anything else?

Can you send me (to my mail, as an attach) a git diff? Or open a jira attaching that diff?

Btw, yes, I'm interested in understanding better how your system works (daemon, attach-detach, and all).

Also, big thanks for taking the time to look into the source code!!!

today i have solved about sms and ussd problem and aded a check in ussd and sms section to check status of dongle connected or not if connected then send ussd or sms otherwise display that dongle is not connected ,and got success; and commited today you can check that my work on https://freeswitch.org/stash/users/shabbirabbasi92/repos/freeswitch/diff/src...

I got the problem of using many modems and losing the sync of tty ports. 1.2.3.4

That problem off ussd and another of sms I found too.

I'm developer, and c programmer,

Maybe we can work together to get best results.

"It's working fine? no calls stuck after you unplug/plug modem? " Yes it is working fine ; i have set gsmopen_serial_sync_period=1 in gsmopen.conf due to this if i unplug modem then it is marked as disconnected and hangsup the call and after this discovery thread wakes up and try to find device after every 30 second if device found then it starts serial monitor thread and exits and it is not effects on other modems i have tried many times to unplug modem during calls and after calls but they discovered fine here,

i am still working on it , and i found problums in my work and corrected it like in previus commit i was found that when i sends a ussd commands to a disconnected modem then cli gets hanged due to there was no check whethere modem is disconnected or connected,now i have added a check to check status connected or not,

"How many modems are you using?" i am just playing with it with only two modems,i am not a Developer just trying to learn, i am using centos 7 64 bit, my system is not in production , just for experimental, and Discovery function in centos working fine

My bad, i looked better and see that you have made a discovery function.

How many modems are you using? How many calls simultaneous? It's working fine? no calls stuck after you unplug/plug modem?

I have found errors in source (master). And have made a lot a tests, like: unplug a modem in a middle of call - try to make a call with a modem that no support voice - send a sms at the same time you made a call - receive a call from modem A and route to modem B

There is more tests that i have made, and made changes to correct it.

Anyway, since i use xml_curl to grab the attached modems, and some modems can be removed/dettached or just have failure of power supply i reload/dettached/remove in according with the system/user interaction.

And, that find_ttyusb_devices, don't work in FreeBSD, witch is the SO that i use *i can't user another system, i have made a lot of modifications in kernel and have a complete custom system based on that called BrbOS, with kernel encryption, custom drivers and other things.

I make the control of calls using event_socket, and make custom routes according with the time, cost, user, configuration, usage, portability, destination...

I need the system working that way, receive events when a modem cannot make calls, and control the modem to reload/attach when i need. So, because of it i create a daemon that i can control and know when a modem changes.

I have found, in freeBSD and debian, a commom problem

Its like, when i start the system for the first time

Lets consider this ModemA (MA) - (ttyU0, ttyU1, ttyU2, ttyU3) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MA was unplugged/have power supply problem

ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MC was unplugged/have power supply problem

ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MC was plugged/redicovered

ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MA was plugged/redicovered

ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

As you see, sometimes the modems don't get the tty sequence 1.2.3.4. They get the sequence of free tty ports And, it's just in this test, when i have modems with 4/3 ttys Sometimes, the modem just RESET, and the tty was not free yet, so the modem jump a number in sequence

MD was unplugged/have power supply problem

ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) -

MD was on, but ttyU12 still oppened by FreeSwitch (mod_gsmopen)

ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU13, ttyU14)

As you see, the discovery will not work sometimes, you need to change to get all ttyports not getting as (ttyFOUND + 1) and (ttyFOUND + 2)

And, like i said before, if you wan't to made changes i'm able to help or to rewrite the module, just need someone to help If you wan't, send me a e-mail or just reply here

Hi: i have made patch for auto reconnect if dongle disconnected and display status of dongle connected or disconnected https://freeswitch.org/jira/browse/FS-8626

i think after this patch you dont need a seprate daemon to run thank u

Hi, i sent a e-mail to you, with the diff, files and give you access to web interface of the system.

I will wait you to read, confirm and reply my e-mail.

Thanks a lot for the help.

today i have solved about sms and ussd problem and aded a check in ussd and sms section to check status of dongle connected or not if connected then send ussd or sms otherwise display that dongle is not connected ,and got success; and commited today you can check that my work on

I got the problem of using many modems and losing the sync of tty ports. 1.2.3.4

That problem off ussd and another of sms I found too.

I'm developer, and c programmer,

Maybe we can work together to get best results.

"It's working fine? no calls stuck after you unplug/plug modem? " Yes it is working fine ; i have set gsmopen_serial_sync_period=1 in gsmopen.conf due to this if i unplug modem then it is marked as disconnected and hangsup the call and after this discovery thread wakes up and try to find device after every 30 second if device found then it starts serial monitor thread and exits and it is not effects on other modems i have tried many times to unplug modem during calls and after calls but they discovered fine here,

i am still working on it , and i found problums in my work and corrected it like in previus commit i was found that when i sends a ussd commands to a disconnected modem then cli gets hanged due to there was no check whethere modem is disconnected or connected,now i have added a check to check status connected or not,

"How many modems are you using?" i am just playing with it with only two modems,i am not a Developer just trying to learn, i am using centos 7 64 bit, my system is not in production , just for experimental, and Discovery function in centos working fine

My bad, i looked better and see that you have made a discovery function.

How many modems are you using? How many calls simultaneous? It's working fine? no calls stuck after you unplug/plug modem?

I have found errors in source (master). And have made a lot a tests, like: unplug a modem in a middle of call - try to make a call with a modem that no support voice - send a sms at the same time you made a call - receive a call from modem A and route to modem B

There is more tests that i have made, and made changes to correct it.

Anyway, since i use xml_curl to grab the attached modems, and some modems can be removed/dettached or just have failure of power supply i reload/dettached/remove in according with the system/user interaction.

And, that find_ttyusb_devices, don't work in FreeBSD, witch is the SO that i use *i can't user another system, i have made a lot of modifications in kernel and have a complete custom system based on that called BrbOS, with kernel encryption, custom drivers and other things.

I make the control of calls using event_socket, and make custom routes according with the time, cost, user, configuration, usage, portability, destination...

I need the system working that way, receive events when a modem cannot make calls, and control the modem to reload/attach when i need. So, because of it i create a daemon that i can control and know when a modem changes.

I have found, in freeBSD and debian, a commom problem

Its like, when i start the system for the first time

Lets consider this ModemA (MA) - (ttyU0, ttyU1, ttyU2, ttyU3) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MA was unplugged/have power supply problem

ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU8, ttyU9, ttyU10) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MC was unplugged/have power supply problem

ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MC was plugged/redicovered

ModemA (MA) - ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

MA was plugged/redicovered

ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU12, ttyU13)

As you see, sometimes the modems don't get the tty sequence 1.2.3.4. They get the sequence of free tty ports And, it's just in this test, when i have modems with 4/3 ttys Sometimes, the modem just RESET, and the tty was not free yet, so the modem jump a number in sequence

MD was unplugged/have power supply problem

ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) -

MD was on, but ttyU12 still oppened by FreeSwitch (mod_gsmopen)

ModemA (MA) - (ttyU3, ttyU8, ttyU9, ttyU10) ModemB (MB) - (ttyU4, ttyU5, ttyU6, ttyU7) ModemC (MC) - (ttyU0, ttyU1, ttyU2) ModemD (MD) - (ttyU11, ttyU13, ttyU14)

As you see, the discovery will not work sometimes, you need to change to get all ttyports not getting as (ttyFOUND + 1) and (ttyFOUND + 2)

And, like i said before, if you wan't to made changes i'm able to help or to rewrite the module, just need someone to help If you wan't, send me a e-mail or just reply here

Hi: i have made patch for auto reconnect if dongle disconnected and display status of dongle connected or disconnected https://freeswitch.org/jira/browse/FS-8626

i think after this patch you dont need a seprate daemon to run thank u
