[solved]no more call received [ModemManager, QMI protocol error]

[alexandre]

Hi,

I run danct-archlinuxARM on my pinephone «convergence pack» with both phosh/ModemManager and plasma/ofono installed. I switch from one to another from time to time using systemctl start/stop… Everything was fine since last week-end : i receive no more call while running phosh/ModemManager. I can provide a whole log file but I think the important things are hereafter. I precise that i can still call and send/receive sms. More surprinsigly, everything still works while running plasma/ofono, and much more surprinsigly, i'm pretty sur having received calls while running plasma and ModemManager (for unknown reason, when ofono dies it often restart ModemManager…) ! I could just stay on plasma, but i'd like better to solve this. Here is a part of the log :

I guess it's solved. The matter didnt come from ModemManager but rather from kdeconnect which became the default call-app !!! removing it fixes this behaviour but I was suggested the following workaround in the calls matrix room (thanks to them) : in /usr/share/applications/gnome-mimeapps.list add the following lines :
x-scheme-handler/tel=sm.puri.Calls.desktop
x-scheme-handler/sms=sm.puri.Chatty.desktop
