My bluetooth controller appears in bluetoothctl:
[bluetooth]# list Controller 08:D8:33:xx:xx:xx BlueZ 5.62 [default] But when I try to connect to a device it gives an error I haven't seen a mention of anywhere:
[bluetooth]# connect E8:06:88:xx:xx:xx Attempting to connect to E8:06:88:xx:xx:xx Failed to connect: org.bluez.Error.NotReady br-connection-adapter-not-powered How to fix this?
Actually, in the version of the distro package of bluez I am using, the default configuration is to not automatically use bluetooth controllers after boot. To enable this, uncomment the AutoEnable setting in /etc/bluetooth/main.conf and set it to true:
[Policy] # ... snip ... AutoEnable=true Then restart bluez:
sudo service bluez restart or whatever the equivalent is to restart a service on your distro.
(solution as suggested by https://wiki.archlinux.org/title/bluetooth#Auto_power-on_after_boot)
sudo systemctl restart bluetooth; blueman-applet, turn my connecting device off and on, right-click on the Blueman applet, and select Make Discoverable; then, right-click on Blueman and go to Devices, right-click on my device, and as soon as my connecting device says Pairing (it says that whether it's pairing or not a while after I turn it on), then click connect; it usually connect immediately. Timing of these steps seems to be important.
