First, thank you for answering.I do not know so much about my BT adapter, but I bought my laptop with Trisquel preinstalled, so I hope it will work well. After I posted my question I managed to send a file with BT to my phone, so something looks like to work. Now I can find my phone by "bluetoothctl", then "scan on". But I can not pair with it.
What should I do?
