Allow the modem to enter soft sleep when we don't talk to the modem using AT commands. This was already the case in suspend, but not during runtime. By only waking the modem from soft sleep when we need to send an AT command, we can save some power.
eg25-manager - Quectel EG25 management daemon
eg25-manager is a daemon for managing the Quectel EG25 modem found on the
Pine64 PinePhone.
It implements the following features:
- cleanly power on/off the modem
- configure/check essential parameters (such as the audio format) on startup
- monitor the modem state through ModemManager
- put the modem in low-power mode when suspending the system, and restore it back to normal behavior when resuming
- monitor the modem state on resume and recover it if needed
Dependencies
eg25-manager requires the following development libraries:
- libglib2.0-dev

eg25-manager is as simple as running the following commands:
