Hi glinet team,

Is there any at command, or any setting in the admin panel to turn off the e750’s modem to save battery ?

If you are comfortable using the command line interface then you can use uqmi to get and set modem parameters. Specifically, from the help text:

" --set-device-operating-mode Set the device operating mode
(modes: online, low_power, factory_test, offline
reset, shutting_down, persistent_low_power,
mode_only_low_power)"

The following command works for me; you shoudl confirm your device address:

uqmi --device=/dev/cdc-wdm0 --set-device-operating-mode persistent_low_power

If that command times out you MAY need to start by releasing client IDs:

uqmi --device=/dev/cdc-wdm0 --sync

Cheers

You can turn the modem’s power off using GPIO.

I forgot how to do this exactly.
