I've uploaded a SRU with the patch now
** Description changed:
- Description of the problem
- A pair of Sony Sony WH-H900N Bluetooth headphones often refuses to re-connect
with a Lenovo V15 G2 ALC laptop. These headphones pair without trouble to a
MacBook Pro and an Android phone.
+ [ Impact ]
- Step to reproduce:
+ Bluetooth devices fail to reconnect after a suspend or system restart
+
+ [ Test Plan ]
+
1. Put the headphones into discovery mode.
2. Go to Settings -> Bluetooth and connect to the headphones.
3. Reboot the laptop.
4. Go to Settings -> Bluetooth
5. Click on the headphones.
6. Try to connect to the headphones.
7. If step 6. fails try to disconnect.
8. Go to step 6.
Expected result:
After step 6 for headphones to be connected and for headphones to announce
"Bluetooth connected".
- Actual result:
- Sometimes the "connected" slider slides back to unconnected. Sometimes the
slider remains "on" but the headphones don't announce that they are connected
and no headphones appear in sound settings.
+ [ Where problems could occur ]
+
+ The change is in the reading of stored device keys. If the patch is
+ wrong it could be that paired devices will not reconnect correctly or
+ might use an incorrect profile.
+
+ [ Other Info ]
How reproducible is the problem:
Fairly reproducible. It can sometimes takes 30 or more connection attempts
before a real connection is established.
