How I got my Microsoft Bluetooth 3600 mouse to work on Ubuntu 17.10

Now I do not know if or why this did the trick, but following the instructions here:

https://askubuntu.com/questions/966734/ubuntu-17-10-not-detecting-bluetooth-mouse

echo "options iwlwifi bt_coex_active=0"|sudo tee --append /etc/modprobe.d/iwlwifi.conf

then you should restart your computer or you can reload your wifi modules. Again in one line:

sudo rmmod iwlmvm iwlwifi && sudo modprobe iwlmvm

…gave a lot of new devices discovered in bluetoothctl, among which I could pair and trust the mouse. This issue was driving me nuts btw.

bluetoothctl

[NEW] Device CE:AB:BA:AB:87:87 BluetoothMouse3600

pair CE<tab completion><return>

trust CE<tab completion><return>

Here is some explanation but seems to go the other way…
