Is there a full list of LTE modules that run embedded linux (and could possibly be accessed via adb or through other means)? I know EC25 only and am fairly sure that all EC2x fall in this category. but how about others?
Thanks.
Quectel LTE module, EC2x，BG96/EG91/EG95 should run the Linux.
Some EC200A and EC200R also run Linux.
The others should run the RTOS.
Do I have to flash special firmware to be able to connect via adb?
For standard firmware, actually Quectel would not provide the adb shell for the module.
There is no special firmware to enable the adb.
For how to enable the adb, we can use the AT+QCFG=“usbcfg” and AT+QADBKEY to enable the adb.
