Auto reconnect Bluetooth devices on Linux

Tuesday, December 17th, 2019

If you were wondering why your Bluetooth devices, such as keyboard and mouse, (…) do not automatically reconnect when you reboot / start your Linux desktop, … It is not enough to just have the bluetooth deamon running. You also need to power it up:

libexec/bluetooth/bluetoothd
bluetoothctl power on

You obviously had to pair and connect the device, before but you also need to trust (because obviously “pairing” is not trusting) …

bluetoothctl scan on
bluetoothctl pair MM:AA:CC:..
bluetoothctl connect MM:AA:CC:..
bluetoothctl trust MM:AA:CC:..

You also need to enable AutoEnable, in /etc/bluetooth/main.conf

[Policy]
AutoEnable=true

Certainly would be too easy in 2019 for stuff to work without reading some freaking manual pages, and internet re-searching the topic a bit, … :-/
