GSM modules

Missing feature

It would be incredibly useful to be able to use a cellular 2G/3G/4G/NB-iot/LTE-catM modem like SIM7000 or Quectel equivalent.

The underlying network stack should be used.

On ESP-IDF this is achieved utilising PPPoS supported by lwIP.

Support for the CMUX GSM 07.10 protocol should be considered during design, as it could allow to simultaneously use GPS, sending AT commands/SMS e.t.c. without interrupting network traffic.

Justification

Many IoT solutions rely on cellular modems for communication.

Workarounds

No workarounds have been found.
Trying to implement using UART wit AT commands is cumbersome and libraries like MQTT, HTTP e.t.c. cannot be reused.

Could we reopen this issue please? PPPoS would be an incredibly useful feature, not just for modems but also for getting internet access over UART connections, using much less power than ethernet magnetics eg https://www.instructables.com/Connect-the-Raspberry-Pi-to-network-using-UART/
