        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?

                  Hi, I was about to post this exact topic.

                  I tried with an SN30 Pro and a Switch Pro and am experiencing the same problem - the setup utility freezes when selecting a security mode.

                  Pi Model or other hardware: Raspberry Pi 4B
                  Power Supply used: Canakit Pi 4
                  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: USB storage stick, keyboard
                  Controller used: 8BitDo SN30 Pro, Switch Pro controller

                  Occasionally after the failed pairing I'm unable to remove the device:
                  alt text
                  Restarting the Pi seems to fix this.

                  EDIT:: Found a workaround from this thread on the official forums:

                  https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=304000&hilit=Bluetooth&start=25

                  At the command line, type these commands:

                  sudo systemctl daemon-reload
sudo systemctl restart bluetooth

                  Then restart emulationstation and go to Bluetooth config. This allows me to pair and use the SN Pro. Rebooting breaks it again, but you don't need to re-pair - type the above into command line again, then go to Connect all paired devices in the Bluetooth config and make sure your controller is on.

                  EDIT 2:: "Pair all Connected" isn't working very well for me anymore. For best results, after every reboot, restart the daemon/bluetooth service, remove the paired device, then pair again. This also will fail occasionally; it seems like if I get the org.bluez.error screen on a boot, nothing will get it to work. Try rebooting again.

                    What Pi4 model do you have ? Can you run cat /proc/cpuinfo and post the output ?

                      It's the Pi 4 B. Results look pretty similar to the one previously posted:

                      2 lines that the console remembers isn't the worst workaround I've ever dealt with :) Thanks for looking at this!

                        Just wanted to confirm this is a 1.4 model (last line) - thank you. Looks like it's not an issue with older models (as @pscotto1234 also noticed), I'm wondering what's different in 1.4 vs older models during the Bluetooth start-up that requiring a restart of the bluetooth service necessary.

                        I have one of the older models (1.1) and can't seem to replicate this either with my current install or with a fresh one.

                          Okay, here is what I have some far.

                          Bought the Bluetooth adapter. Was able to connect my 8BitDo SN pro+ Worked for a few reboots. Then stopped working completely. Unpaired tried to pair.

                          Then get the error - “ bluetooth device (Creating device failed: org.bluez.Error.AlreadyExists:already Exists)

                          Any ideas. Thanks

                            @velez66 Did you disable the onboard Bluetooth after connecting the dongle ?
                            Also, the 8Bitdo gamepads have a tendency to not reconnect when you're just rebooting the Pi - usually powering them off and on is enough for them to re-connect.

                              @mitu Hello - Yes I did. Also reboot and did a complete power off.

                              Note: I am using a NESPi 4 CASE, which I have heard that the SSD feature creates interference with the onboard Bluetooth.

                              It might be affecting the Bluetooth dongle that I bought

                              Going to try the Bluetooth dongle on my Argon case to eliminate that possibility and for troubleshooting

                              Help and input it is appreciated.

                              Thanks a lot!!

                                Okay, got it to work on the Argon Case using the Bluetooth Dongle. Not sure if I am going back to the Retroflag Nespi 4 Plus and try again. The Nespi Case is really nice.

                                  Well back to the error again. Extremely frustrating.

                                  Worked for a few hours. Shutdown the system for the night

                                  And today it doesn’t recognize the controller again

                                    @velez66 did you press "Set up udev rule for Joypad" when you got it to connect last time? If you don't do that with 8bitdo controllers they won't be recognized after a reboot.

                                        Thank God for this thread, can't find anything anywhere I was going crazy, new pi 4 8gb, couldn't add 5 different expensive Bluetooth devices, froze everytime at same screen, 3 days of beating my head into a wall until I stumbled until this thread, bless you all!! Definetly an OS problem.

                                          @ttazer yeah, definitely a disconnect between the OS and the newer Pi 4 boards, because I've had a couple friends with older Pi 4 boards say theirs' was fine. Hopefully it's something that can be resolved in the future through a software update instead of a hardware update :)

                                            I hope a software update can resolve. Other system like recallbox works fine with Bluetooth.
