@qstyler said in Cannot setup 8bitdo bluetooth adapter on Pi 4:

Hi! I'm trying to set up an 8BitDo BlueTooth adapter but it doesn't seem to work for some reason.

First of all, I disabled Bluetooth in the config.txt file by adding dtoverlay=disable-bt

Then I plug my dongle and try to do bluetoothctl, but it hangs forever.

To fix the issue I tried to run the following:
$ sudo systemctl enable bluetooth Synchronizing state of bluetooth.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable bluetooth $ sudo systemctl start bluetooth
This command gives no output...

And this is a status of the bluetooth:
$ sudo systemctl status bluetooth * bluetooth.service - Bluetooth service Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled) Active: inactive (dead) Docs: man:bluetoothd(8) Apr 09 11:24:42 retropie systemd[1]: Condition check resulted in Bluetooth service being skipped.
If I try to get a list of USB devices, I can see my dongle, but without a name (device 004):
$ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 2dc8:3107 Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Here's the full dmesg output, maybe this will help.

I'm using Raspberry Pi 4 Model B Rev 1.2

There are no other USB devices connected to my Raspberry.

And I'm using a default usb-c power adapter that came in a box.

The 8bitdo bluetooth adapter is not actually a bluetooth adapter in the traditional sense. When you plug it in, it is treated as a USB controller, not a bluetooth radio. To connect a controller to the receiver, press the pairing button on the adapter, then press the pairing button on your controller. When both lights are solid, the connection is made. It also means you can only have one controller paired to the adapter at a time, and need multiple adapters if you want to pair multiple controllers. Changing bluetooth settings in the OS will have no effect on the adapter.
