Comment # 2 on bug 1203722 from Episteme PROMENEUR

I restart the PC

The PC does not connect automatically to the smartphone.
I check in the plasma widget that the smartphone is in the state "trust".
At the PC I connect the smartphone, the connection fails.
I run "bluetoothctl trust 90:06:28:B6:B1:B6"
At the PC I connect the smartphone, the connection fails.
then I run
bluetoothctl connect 90:06:28:B6:B1:B6
Attempting to connect to 90:06:28:B6:B1:B6
Failed to connect: org.bluez.Error.Failed le-connection-abort-by-local

I try to disable then enable bluetooth with the plasma widget. Furthermore, I
can connect no more the smartphone from the PC.

I can connect the PC from the smartphone. The HSP is used by default.
At the smartphone when reading the available protocol I see HSP enabled and the
A2DP disabled.
