Pair Bluetooth Controllers - manual setup

You need to establish a SSH connection or a terminal windows with keyboard to accomblish this further. You can connect your bluetooth controller manually by doing some commands step by step.

Get started by typing bluetoothctl and hitting [Enter].

Now you are in the Bluetooth control unit. Type following commands and confirm every single one with [Enter]

  agent on
  power on
  scan on

Now set the controller in pairing mode! This strongly depends from your controller type.

An example of the output you would see from running all the commands successfully:

[root@BATOCERA /userdata/system]# bluetoothctl
Agent registered
[bluetooth]# agent on
Agent is already registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# scan on
Discovery started
[CHG] Controller 43:45:C0:00:1F:AC Discovering: yes
[NEW] Device E4:17:D8:C2:0B:0E 8BitDo M30 Modkit

If you're having trouble detecting devices, check out the Bluetooth section on the troubleshooting page.

Now we want to connect to our controller. So we type following commands to connect to discovered controller with MAC address E4:17:D8:C2:0B:0E properly. Wait a few seconds after entering the commands in order to ensure they are processed successfully.

  pair E4:17:D8:C2:0B:0E
  connect E4:17:D8:C2:0B:0E
  trust E4:17:D8:C2:0B:0E

This would be the output from our example:

 [bluetooth]# pair E4:17:D8:C2:0B:0E

Type devices to see a list of devices configurated in your BT setup.
Type remove MAC-ADRESS to remove single devices
Type yes if you are asked for authorization progress or enter PIN

If you have multiple Bluetooth adapters on your machine and you want to tell which one is used, you can use the command hcitool dev to list them all. On my setup, hci0 is the internal BT on my Pi4, and hci1 is an additional USB BT module:

 # hcitool dev
     hci1    90:80:62:00:88:00
     hci0    DC:A6:32:04:10:7F
 # bluetoothctl 
 Agent registered
 [bluetooth]# scan on
 Discovery started
 [CHG] Controller 90:80:62:00:88:00 Discovering: yes

Still needs further investigation/testing.

batocera-bluetooth list                      Print the list of currently trusted and saved Bluetooth devices.
batocera-bluetooth trust                     Trust a new, randomly(?) selected device. Good luck!
batocera-bluetooth remove <device address>   Removes (untrusts) specified Bluetooth device from the list and removes its connection from memory.
batocera-bluetooth save                      Saves the newly trusted device to memory.
batocera-bluetooth restore                   Undoes any trusted but not currently saved device and restores from memory.
