esp_modem and SIMCom A7672x
Posted: Wed Mar 01, 2023 7:34 am
Hello.
I'm trying to connect ESP32-S3 with SIMCom A7672x module via USB and using truncated pppos_client example with VSCode for it.
The problem is that i can not read correct data from module, although it can send SMS.
So, how i can turn on extended log information for esp_modem and usb components to try understand what could go wrong?
