From 7423d2e58409029c1440ef91033b945fbe94c359 Mon Sep 17 00:00:00 2001 From: Pau Espin Pedrol Date: Fri, 25 Aug 2017 12:58:25 +0200 Subject: modem: Attempt fixing crash from Register() dbus method Register() method returned today this error which is expected acording to ofono documentation API. In this case it probably happens because the modem internally starts registering at some point between the time Scan() is finished and we call Register(). In this case it is fine for us and we should just ignore the error. A helper method is added to check for this as so far it seems tricky to check error information coming from pydbus. I could not reproduce this issue locally so I could not test that the helper function is going to handle it correctly when it is triggered. That's why I added extra debug information to be able to fix it next time it is triggered.
