BGS5T - Cannot manage CSD incoming call from Java Midlet | Thales IoT Developer Community

January 16, 2015 - 1:28pm, 3026 views

Hello,

I am porting a java Midlet from TC65T to BGS5T, and I have a problem with CSD incoming calls.

Our Midlet manages incoming CSD calls with a class called CSDListener that implements ATCommandListener, where we implemented, among others, this method:

public void RINGChanged(boolean arg0) {

if (arg0 == true) {

String response;

response = atc.execCommandCSD("ATA");

...

}

}

Then we register CSDListener with ATCommand.addListener() this way:

...

commandCSD = new ATCommand(true);

csdListener = new CSDListener();

commandCSD.addListener(csdListener);

...

But when I start a CSD connection from a TC65T to the BGS5T, this method is never called, no way to catch the incoming call.

The SIM cards we are using are enabled for CSD connections. Indeed, if I substitute the BGS5T with a TC65T with the same SIM card and the same software the CSD call works very well.

I tried to call the BGS5T without the midlet running, and I saw the RINGs arriving on the serial interface, so the module effectively can receive the call.

I tried to check the at^scfg configuration about 'Ringline' parameters but I noticed something strange:

The At command documentation (bgs5_atc_ext.pdf) show these commands among others:

^SCFG: "URC/Ringline", (list of supported <urcRinglineCfg>s)

^SCFG: "URC/Ringline/ActiveTime", (list of supported <urcRinglineDuration>s)

But they are not present in my BGS5T when I type at^scfg?, they are not known by the module.

May someone help me, please?

Thank you very much!

We are using these settings:
