I am trying hard to connect the Logitech H800 headset to an Ubuntu 18.04.3 system on an HP Elite Book 850 G2 with Intel Core i7-5600 CPU @ 2.6 Gh x 4, a 64-bit system. In other words: The hardware is not bad at all.
I have been trying the command line pairing_tool which tries to connect using the Logitech Unifying Receiver. It doesn't recognize the H800.
I have been trying the graphical blueman-assistant which tries to connect via bluetooth. It "failed to add device".
I have been trying as well the command line tool bluetoothctl. It recognizes the H800, but when it comes to pairing, using the commeand "pair MAC:adress", it gives me the error message "AuthenticationFailed".
Some further ideas how to connect a Logitech H800 headset to an HP Elite Book 850 G2 (two not so bad pieces of hardware ...) ?
I would definitely appreciate.
Best, Simon
