TC65 /XT75 - how does the GSM handshake work?
Hi Everybody!!!
I am develloping a calling application and my class ATListener won't hear an URC while I'm dialing!!
What I do is: when the person pushes a button the module calls a number from the SIM card.
However, if I push the button again to hang up the call, the module won't be listening to the interruption. This happens exclusively during thehandshake+dialing stages, there are no problems while the call is active (it is possible to hang up).
Does anyone know how to avoid this?

I'm using only one!! But as soon as it receives an URC it leaves the Listener through a Thread ATHandler where it handles the command thus freeing the listener quickly to listen to other URCs (I assume).
It is immediatly after the "atd0630490293;" command and it remains "deaf" until the call is answered on the other side....
should I use another ATListener?

Let me see if I get this straight...
I'll use one listener for one set of commands, let's say for all commands except dialing.
private ATListener ComList = new ATListener();
private ATCommand ATCmd = new ATCommand(false);
ATCmd.addListener(ComList);
And then another listener with another set of commands, which does the dial commands?
private ATListener ComList2 = new ATListener();
private ATCommand ATCmd2 = new ATCommand(false);
ATCmd2.addListener(ComList2);
and then I can do
ATCmd2.send("atd"+callNumber+";\r");
and
ATCmd.send("at+cops?\r");
?
Also, I listen to many URCs such as:
"^SCPOL: "
"NO CARRIER"
"+CMTI :"
"+CLIP: "
"^SGPSP: "
"+CIEV: "
Who will hear those? Both listeners? Or let's say, the CIEV ones will be heard by ATCmd2 and ^SCPOL will be heard by ATCmd?
Sorry for being a noob...
Thnxs!!
