ESP32-ADF SIP VoIP demo

[jc2020]

Hello,

I've got a REV-C ESP-ADF board with an LCD module (MOD-LCD2.8RTP).

I can compile the SIP VoIP demo and flash but nothing displays on the LCD.

What could be the issue?

Thanks!

Here is the error log:

Has this demo worked for anyone without any modifications?

We did some tests and indeed it seems there is some software issue with the display libraries but we are unable to fix it for now. One thing you can use to prove that it is not hardware issue is to go to file "void_app.c", and comment out function:

//periph_service_set_callback(input_ser, input_key_service_cb, (void *)board_handle);

It is around line 489.

Then test the display.

Edit: It that this is probably caused by differences in ESP-ADF version used. Different ESP-ADF versions produce different results. Maybe also try with older ESP-ADF version.

Hi, first test, compile ok.

Call from my deskphone to olimex voip demo or other way.
Display goes blank after answering call and get this error in serial monitor:
W (224991) AUIDO_MEM: Can't support stack on external memory due to ESP32 chip is 1

Both tests audio channel gets established but first impression is poor audio quality from speakers. Will test with headphones.

[emiel]

ok microphone or headphone microphone gives good audio to other party.
Onboard speakers or headphone gives very bad audio quality.

Does anybody know how to fix this?

I have choosen G711u (Default codec for all countries except USA)
Will test with G711a (USA default codec)

[emiel]

Don't have the board at home to test but could this be something regarding the poor audio?
