A possible solution could be to setup a self managed uart port As long as you don't use the DATA mode, it is possible to add a second serial port (UART_NUM_2) to the same pins, and only use them for reading AT response data and URCs. Example code [Codebox] #include <stdio.h> #include <string.h> #inc...

For my setup it was also required to set the network mode to GSM only: void configure_network_mode_gsm_only(esp_modem_dce_t* dce) { ESP_LOGI(TAG, "Setting network mode..."); char resp[32]; esp_err_t err = esp_modem_at(dce, "AT+CNMP=13\r", resp, 1000); if (err != ESP_OK) { ESP_LOGE(TAG, "esp_modem se...

Initialising the SIM7000G using TinyGsm, so that the serial communication is working, and afterwards flashing the firmware using esp_modem will allow for serial communication to work. Something is definitely not OK during serial setup using the esp_modem component (in combination with the lillygo bo...

Hello, SIM7000 is support is now integrated. But I'm also in the same situation. Arduino libraries like TinyGSM work with the Lillygo sim7000g without any problems. But we also want to use the ESP-IDF API for a more mature project setup. As far as I can tell, the esp_modem component issues seems to ...
