1. After opening line I am sending AT#DTMF=1 to enable DTMF decoder. After receiving DTMF-tone that is expected, I am trying to disable DTMF decodet with AT#DTMF=0, but exception raised and Python scrip stps.
2. After opening line I am sending AT#SPCM=1,1 to send PCM soud on audio channel and also exception raised. In command mode SPCM is working even when the line is closed.
Module is GL865-DUAL, firmware 10.00.155.
Nikolay can you post the pieces of code throwing the errors, and errors description?
Sorry, it was my fault. Using readlines instead of readline when reading sound file for SPCM.
Btw, can I use DTR line instead of ‘+++’ to exit PCM sending faster?
Yes it is possible to close SPCM with a transition on DTR after having set AT&D1Please be aware of the fact that exit from DATA mode is signaled by DCD. No message like NO CARRIER is sent trough UART.
