Issue happens for arale only when connecting the same BT mouse, but krillin and mako work as expected.

Here are some more info when connecting with Arale:

Can you please attach the missing syslog as mentioned in https://wiki.ubuntu.com/DebuggingBluetooth

That is the most interesting one.

[Simon Fels (morphis)]

Also can you give me the exact name of the mouse you're using?

[TarotChen (tarotchen)]

Mouse: Logitech M336

[Simon Fels (morphis)]

It looks like the mouse is correctly hooked up into the system:

Nov 26 02:41:47 ubuntu-phablet kernel: [ 310.071943] hid-generic 0005:046D:B014.0001: unknown main item tag 0x0
Nov 26 02:41:47 ubuntu-phablet kernel: [ 310.072340] input: Bluetooth Mouse M336/M337/M535 as /devices/virtual/bluetooth/hci0/hci0:50/input6
Nov 26 02:41:47 ubuntu-phablet kernel: [ 310.086467] hid-generic 0005:046D:B014.0001: input: BLUETOOTH HID v12.00 Mouse [Bluetooth Mouse M336/M337/M535] on 38:bc:1a:29:0e:89

However sadly the last part of the syslog where all the debug switches are turned on you didn't tried to connect the mouse as it seems.

Can you remove the mouse from the phone, make sure all debug switches as described in https://wiki.ubuntu.com/DebuggingBluetooth are enabled, and then pair, connect and try to enable the mouse again so that we get all necessary details in the syslog?

Thanks!

[Simon Fels (morphis)]

Thanks for the detailed syslog!

Can you run

 $ sudo btmon -w test.snoop

then reproduce the bug (remove the mouse in settings first and then reconnect/repair).

Afterwards send me the test.snoop by mail.

[Jonas G. Drange (jonas-drange)]

Simon, is something lacking in System Settings or is this a problem in bluez?

[Simon Fels (morphis)]

@Jonas: Seems to be a problem with BlueZ (either kernel or userland).

Ubuntu Touch is no longer supported.
