adl_audioSubscribe Failure


#1

Hi

I have an Open AT Application that I am developing to decode DTMF from a caller. The problem I am having is at the very first part.

When the device hits the following line it just reboots itself:

audioHandle = adl_audioSubscribe (ADL_AUDIO_VOICE_CALL_RX, AudioEventHandler, ADL_AUDIO_RESOURCE_OPTION_FORBID_PREEMPTION);

The Wavecom sample app does the same as well. Do I need to do anything before this call can be made to stop it from failing?

I am using Open AT 4.23 on a device running 663c

Thanks

Try with adl_atCmdCreate(“AT+WDDM”, …).

That works well. Still no idea why the subscribe fails

Thanks
