[Freeswitch-dev] error in con:pop wrong number of args

[grmt]

What version of FS are you running? You need a fairly recent version of FS to support the timeout parameter of con:pop

Pop(1,5) means block and wait,  but only 0.05 (s) 
Is that what you want?  I guess not, you usually don't want to block a lua script that handles audio.
And you certainly don't want to repeat this "blocking" 20 times per sec, polling for DTMF events

There are better ways to catch DTMF (setInputCallback  ...)

( I think anthm answered you on IRC..)

I am getting this error from the test code below. I have used 2 arguments but it is picking up 3?


2012-04-03 21:16:08.583714 [ERR] mod_lua.cpp:191 Error in pop expected 1..2 args, got 3 stack traceback:

dtmfbuffer = ""

con = freeswitch.EventConsumer("DTMF")

session:setVariable("playback_terminators", "0123456789") session:execute("playback", "sound/test.wav")


while ((session:ready() == true)) do


 for e in (function() return con:pop(1,5) end) do

 event_name = e:getHeader("Event-Name") or ""
 
 if (event_name == "DTMF") then

 print(dtmfbuffer)
 end

 end

end

session:hangup()
