      Pi Model or other hardware: Raspberry Pi 4B
      Power Supply used: official Pi 4 supply
      RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.7.1
      Built From: Pre-made image from website
      USB Devices connected: Wireless USB keyboard & mouse
      Controller used: 8BitDo SN30 pro+

      Hey guys! I am unable to get bluetooth to work at all, even after a completely fresh install. I am able to get the Pi to see the 8bitdo controller, but I am getting a freeze in the script upon choosing a security mode, and am unable to interact with it and have to CTRL+C out of it. I've tried with multiple controllers, and have the same thing happen. Is there a problem in the script, with bluez, or is my board faulty?

      Thank you so much!

        If the controller is connected in XInput mode, try installing the xpadneo driver from RetroPie-Setup before pairing the controller.

          @mitu Okay, I've installed the driver and tried to pair the controller afterwards. I still am getting a freeze when choosing "DisplayYesNo" in the security mode section. I'm not sure if this is even related, but the following output appears when pressing CTRL+C to exit the script:

          ^CTraceback (most recent call last):

            @jtcuth48 When using Ctrl+C, the message is normal. Have you updated RetroPie-Setup after you installed the 4.7.1 image ?

              @mitu Yes I have. If it helps, I am able to successfully connect with bluetooth on other images such as the latest version of Raspberry Pi OS released on March 4th

                RetroPie is based on Raspberry Pi OS (the Lite version), so if you've updated RetroPie-Setup and the OS/packages, it should have the same software as on a Raspberry Pi OS image.
                If you've update RetroPie-Setup, can you post the exact version of RetroPie you have installed ?

                    Can you connect via SSH (as the normal pi user), run bluetoothctl from that login session and then try again the pairing from RetroPie-Setup ?

                    EDIT: if you don't have SSH enabled, you can exit EmulationStation, login in a second screen (Alt+F2 would get you a 2nd login screen, Alt+F1 switches back to the main screen) and start bluetoothctl from there. You can run RetroPie-Setup on the 1st login screen with

                    cd RetroPie-Setup
sudo ./retropie_setup.sh

                      @mitu Okay, I just did it, and it froze at the same spot on the GUI. bluetoothctl spat out the devices in range while doing the search, that ended with the following lines:

                      [CHG] Device 8:BIT:DO:MAC:ADDRESS:HERE Connected: yes
[CHG] Device 8:BIT:DO:MAC:ADDRESS:HERE Connected: no

                      So it looks like it connected for a split second maybe? The controller kept acting like it was still syncing until it timed out.

                      A minute later it spat out this stuff:

                      [DEL] Device RANDOM:DEVICE RANDOM-DEVICE
[DEL] Device RANDOM:DEVICE RANDOM-DEVICE

                      EDIT: the device now shows up in the list of paired devices, but refuses to connect.

                        @jtcuth48 You should remove the device from the list of paired devices before re-attempting to pair.

                          @mitu Unfortunately, same result, freezing when choosing "DisplayYesNo". I even tried the other options but no dice

                            Hi,
                            i have exactly the same problem with a 8bitdo zero 2.
                            Can't make it to connect in any way.

                              @link3384 Yeah, I've tested a friend's board (same model as mine) and it has the same issue. I think it's a problem on Raspberry Pi OS' end. I've had some luck with running "sudo service bluetooth restart" and then connecting, but it's hit or miss. Sorry I can't offer more assistance, this is a real bummer

                                I think it is a problem of retropie 4.7.1.
                                I can't find retropie 4.6 anywhere to test if it works there.
                                When i put recalbox to the sd card the 8bitdo connects in one minute and it works fine.

                                    I'm having same issue with raspberry version 1.4.
                                    @jtcuth48 could you check your board version using following command?
                                    cat /proc/cpuinfo/

                                      Here is another piece of information. I have two Raspberry 4 boards. One was upgraded to boot from USB {SSD) the one other one has not been upgraded.

                                      Bluetooth devices connect right away to the one that has not been upgraded. On the one with the USB boot upgrade will not connect at all, it will not complete the security phase of the Bluetooth connection process.

                                      Also I have tried both boards using Batocera and the connection is flawless. But I prefer to use Retropie for my emulation.

                                      Thanks 😊

                                        EDIT: A cheap USB bluetooth dongle combined with disabling onboard bluetooth fixed the issue, the controller connected like butter. Looks like the issue is likely with the bluez package in Pi OS.

                                        Guys, I've had success with both Recalbox and Batocera straight out of the box, but Raspberry Pi OS itself has the same issues as Retropie so I think it's on their end possibly, and I don't think it's an issue with the 8bitdo issue either, I think the version of bluez preinstalled is janky. Until this is fixed, I think I may stick to recalbox because it seems to just work.. I would prefer Retropie but if it doesn't work then I don't know.

                                        @pscotto1234, the output of that command is:

                                          You have a 1.4 model. I said in another 3d as well that the problem is mainly related with new raspberry.
                                          I think that the problem can only be resolved by upgrading bluetooth driver.
                                          @jtcuth48 could you tell me what BT dongle are you using?
