Bluetooth mouse disconnected immediatly after connection

Hi,

Since a few days, the bluetooth does not work anymore on my laptop (Dell XPS-15 9550).

Trying to connect the mouse starts an endless loop of fast connections and disconnections.

`bluetoothctl` shows this:

[CHG] Device C0:D7:6E:67:47:F3 Connected: yes
[CHG] Device C0:D7:6E:67:47:F3 Connected: no
[CHG] Device C0:D7:6E:67:47:F3 Connected: yes
[CHG] Device C0:D7:6E:67:47:F3 Connected: no
[CHG] Device C0:D7:6E:67:47:F3 Connected: yes
[CHG] Device C0:D7:6E:67:47:F3 Connected: no
...

`sudo /usr/lib/bluetooth/bluetoothd -n -d` gives me this (for each connection/disconnection):

...
bluetoothd[7299]: src/adapter.c:resume_discovery() 
bluetoothd[7299]: src/adapter.c:trigger_start_discovery()

bluetoothd[7299]: src/device.c:device_bonding_complete() bonding (nil) status 0x0e
bluetoothd[7299]: src/device.c:device_bonding_failed() status 14
...

Also my bluetooth headset isn't detected anymore.

I couldn't find any relevant package update in the logs around the moment bluetooth broke. networkmanager maybe.

I have the same issue using the LTS kernel.

Any idea? Thanks.

Re: Bluetooth mouse disconnected immediatly after connection

I tried downgrading bluez packages but that doesn't fix anything

Re: Bluetooth mouse disconnected immediatly after connection

I also tried downgrading the entire distribution to a date I know everything was fine and replacing /lib/firmware/brcm/BCM-0a5c-6410.hcd with an older version, still no luck.

I unpaired the mouse. Now when I try to pair it again I have almost the same result:

[bluetooth]# pair C0:D7:6E:67:47:F5
Attempting to pair with C0:D7:6E:67:47:F5
[CHG] Device C0:D7:6E:67:47:F5 Connected: yes
Failed to pair: org.bluez.Error.AuthenticationFailed
[CHG] Device C0:D7:6E:67:47:F5 Connected: no

`sudo /usr/lib/bluetooth/bluetoothd -n -d` gives me this:

I'm now looking for information about the 0x03 code in `src/adapter.c:pair_device_complete() Failed (0x03)`

Re: Bluetooth mouse disconnected immediatly after connection

I found a workaround using a USB controller. Everything seems to work as normal with it.

I have still no idea why the integrated controller stopped working though. I noticed my laptop is not discoverable with the integrated controller, despite bluetoothctl saying it is.
