During disabling of gps sources the bitmask that keeps track of them is
updated incorrectly. Instead of removing the current source, all other
sources are removed from the mask.
One problem that arises from this is, that when you enable GPS after it
has been disabled completely (e.g. by disabling all GPS sources), the
code will not send a "+CGPS=1,1" command because it incorrectly assumes
that GPS is still enabled on the device.
The SIM7600E ends up emitting these URCs with too many <CR>s, and the
generic +CRING handler doesn't catch them, interfering with other
actions, e.g.:
$ sudo mmcli --call 1 --accept
error: couldn't accept the call: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Failed: Couldn't accept the call: Unhandled response '+CRING: VOICE
+CRING: VOICE''
Just processing and parsing them for now, so that they don't interfere
with other commands:
$ sudo mmcli --call 1 --accept
error: couldn't accept the call: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Failed: Couldn't accept the call: Unhandled response '
VOICE CALL: BEGIN''
