Bluetooth Mouse Pairs But Doesn't Work

Question

Just did a clean install of 16.04 and my Logitech MX Master won't work. I even tried to use blueman to no avail.

Anyone get it working? I used blueman to get it working on 15.

Thanks in advance!

Does the mouse connect? Are you running a power indicator (bug 1098959)? Does your linkkey appear in /var/lib/bluetooth///info? — ubfan1, Apr 24 '16 at 05:29
@ubfan1 It 'pairs', and the mouse thinks it's connected, but it doesn't do anything. Don't think I have a power indicator, and no linkkey... see contents above in my edit. — vmitchell85, Apr 24 '16 at 13:41

I got it working by using the hciconfig answer here: https://askubuntu.com/a/660918/534356

Ironically I tried this before and it didn't work... but after re-installing Ubuntu 16 this did solve my problem!

Thanks @Tobi

Try adding the equivalent linkkey paragraph (use the Key your mouse has) to the info file and change the "Trusted" to true.

[LinkKey]
Key=532EE33E7E50E79AB350554D63226EA1
Type=4
PINLength=0

The trick is to find the key. It may be dug out of the Microsoft registry if you can pair the mouse on a Windows macnine, or on another linux machine. Older Ubuntu (bluez4) will have the keys in a file like /var/lib/bluetooth//linkkeys.

First try changing the "Trusted" and adding a linkkey with a bogus key like DEADBEEFDEADBEEFDEADBEEFDEADBEEF or any random hex value. Then remove the device from the pairing list and re-pair it. Hopefully the new key will be inserted and used to let the mouse work. Blueman has a trust button, try that if you didn't already.

A attempted the bogus key, after re-pairing it removed the whole LinkKey section from the file. I'll see if I can pair it with another computer and get the linkkey — vmitchell85, Apr 24 '16 at 17:27
