These are all the base commands that appear in Quectel's AT Command Manual (Version 2.0). The specific GNSS/GPS and Application control commands are not included here, though they will be added when this list is ready.
- AT+=? Checks if the command exists
- AT+? Prints the values for a specific command
To connect to the serial terminal with local echo and automatic LF trimming, you can use sudo picocom --echo --omap ignlf /dev/ttyUSB2.
Alternatively, you can use mmcli to run a command non-interactively: sudo mmcli -m any --command='AT+QMBNCFG="list"'.
In systemd OSes such as Mobian as of 2023, you will likely need to stop ModemManager and run it in debug mode in a separate terminal: systemctl stop ModemManager; ModemManager --debug, and then run mmcli commands as ordinary user.
Handled by can be
- DSP: Handled by the ADSP firmware with no interaction from the userspace
- Userspace: Handled only by the userspace
- Userspace+DSP: Handled by the ADSP first, then notified to the userspace via IPC
Implemented can be
- Yes: The command is implemented and should be working
- No: The command is not implemented
- Dummy: The command blindly responds OK to whatever value you send, but won't do anything
- WIP: Work in progress

[1]: Diag port is hardwired from LK to the userspace by the firmware. If GPIOs are available in your platform it'll just work(tm), disabling it will probably not work though
[2]: FOTA functionality is completely removed in this firmware
[3]: i2c is disabled for the most part in the kernel and userspace support is removed by default. Handling i2c from AT command interface is not supported
[4]: Qualcomm IZAT is removed from userspace. GPS, GNSS and A-GPS work but the modem will be unable to do standalone A-GPS tracking without cooperation from the PinePhone
[5]: Userspace ignores QSCLK config.
[6]: USB audio functionality will need changes in your ALSA config, make sure you check out @marcin's guide here to make it work
[7]: QGMR has been replaced in this firmware to report the firmware version instead of the ADSP version, so fwupd doesn't need to query different commands depending if you're running stock or this one
