Bluetooth tethering used to work on Jolla via the "Tethering" app (https://github.com/jlehtoranta/harbour-tethering-gui), but no longer works since 18.104.22.168. This is already reported to the app developer (https://github.com/jlehtoranta/harbour-tethering-gui/issues/4) but I took a look at the app code and realized it is only a frontend that makes dbus calls to connman, and that the problem appears to be at connman - and thus probably system level rather than a problem with the "Tethering" app itself. Specifically, attempting to enable "Tethering" for bluetooth with Connman via dbus, eg
dbus-send --system --print-reply --type=method_call --dest=net.connman /net/connman/technology/bluetooth net.connman.Technology.SetProperty string:Tethering variant:boolean:true
Error net.connman.Error.NotSupported: Not supported
Has something changed with connman or with the bluetooth driver or something in 22.214.171.124?
As bluetooth tethering is a really valuable feature for me (and I'm sure many other people), I would greatly appreciate it if someone could take a look and see if this can be properly diagnosed and fixed up :)
