esp_modem and SIMCom A7672x

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.

Code: Select all

I (10347) PPPoS_SimCom: Initializing esp_modem for the A7672x module...
I (10347) PPPoS_SimCom: Waiting for USB device connection...
E (11787) PPPoS_SimCom: esp_modem_get_signal_quality failed with -1 ESP_FAIL
I (11787) PPPoS_SimCom: Signal quality: rssi=-2143830227, ber=1070177312
I (12847) PPPoS_SimCom: IMSI=OK
22383753301 // INCORRECT
I (12857) PPPoS_SimCom: Module name=OK
2E-FASE // INCORRECT
I (12867) PPPoS_SimCom: IMEI=OK
11054942966 // INCORRECT
E (12877) PPPoS_SimCom: esp_modem_get_operator_name failed with -1
I (12877) PPPoS_SimCom: Operator=`��?, Act=1070177376 // INCORRECT
I (13877) main_task: Returned from app_main()
So, how i can turn on extended log information for esp_modem and usb components to try understand what could go wrong?
