I just tested suspend on my L5 using echo mem | sudo tee /sys/power/state with the kernel being 5.16.0-1-librem5.
- It does suspend.
- Now we dial in.
- First ring and L5 is waked up showing the terminal we executed suspend.
- Then it looses the modem or the connection until the 2nd ring.
- 2nd to 3rd ring it has reconnected to 4G and calls kicks in to answer the phone. Maybe by now we have reached the 4th ring. Stays in 4G since I have enabled VoLTE.
But the interface does not provide the means to auto suspend. Will 5.17 be available soon? Will it give the possibility to enable the auto suspend?
