~mil/sxmo-tickets#123: 
4G stops working after CRUST

After a couple times going into deep sleep, I can't get 4G to work until I reboot the phone. Toggling the modem doesn't work. Activating the connection times out, notification shows an error connecting to ' ' (blank)

I'm on the nightly ISO, everything up to date, issue has been there since I installed sxmo.

Edit: nevermind, still broken

https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/407 Latest mm fixes this and has been in the repo for a couple of days - so far my 4G has been working reliably. If anyone else noticed the same, feel free to set this to resolved, otherwise I'll do it myself after some more time.

This script in mobian works reliably- https://forum.pine64.org/showthread.php?tid=12279

I agree, that script is reliable in restoring the data connection, but not in ringing the phone in time during the wakeup from CRUST. When the modem resets the usb connection internally, the script would be stuck on waiting for ttyUSB for a long time, and during that time the call on the caller side terminates.

As I was saying in ticket #116, my workaround was to do the unbind and bind as it happens in the script always right after the wakeup from CRUST. Doing that, the connection is always restored, and my BH always rings reliably on the 3rd/4th ring on the caller side.

Yes, I've discovered programmatically replugging the SoC (usb 3-1) works but please see #130, sxmo_postwake.sh does not get called. I'll try to use the script arjuna linked until the postwake hook works and I can do it there

I'm using mobian for now and found the wakeup from CRUST during incoming calls is not working properly..It works fine sometimes. But found the script quite useful for data which seems to be working fine for me. My UBports edition has faulty WIFI/Bluetooth module which stopped working after 3 months of usage and no reply from pine64 team as it is out of warranty, now just relying on 4G data and this script is quite useful.
