PLSx3 MQTT looses conection after voice call | Telit Cinterion IoT Developer Community

September 14, 2023 - 8:39pm, 612 views

Hi, help is needed

I have built an application based on the MQTT example included in the SDK, and all has been stable for some weeks.

However, after experimenting with some FTP downloads and some AT+CGDCONT trial and error, the MQTT setup looses connection after a voice call has been received. As long as there are no incoming calls, everything works fine

A completely new modem right out of the box still works fine. I check that AT+CGDCONT settings are identical between new and old modems, but i find no differences and nothing helps.

Resetting the modem with AT&F, ATZ  makes no difference.

I try to download new firmware, but the modem will not update. See screendump below.

Any idea of how I can reset or fix the modem??

 

Thanks Tore
