      Thanks gentlemen.

      @mitu I've uninstalled ps3controller and reinstalled sixaxes, unfortunately the issue persists.

      @psyke83 I've made the changes to /usr/bin/btuart as suggested. The issue is a lot less, but it still happens, just less often.

      I can try a USB Bluetooth controller. Do I need to disable the onboard Bluetooth and if so, how would I go about doing this?

        Edit the config.txt file from your SD card (should appear in the BOOT partition on your PC when you insert it) and add a line with

        dtoverlay=pi3-disable-bt

          Thanks mate, I'll try this tomorrow and then install a USB Bluetooth dongle to see if it fixes the problem.

            I couldn't wait till tomorrow. I've dug up an old USB BT dongle, applied the above line to the config and everything is working as it should. Thank you very much gentlemen.

              Is this the same as this issue, where motion controls of the controller were causing it it to jump around erratically? https://retropie.org.uk/forum/topic/17650/dualshock-controllers-on-4-4-with-3b/34. Search that page for "rsn8887 25 Jun 2018, 13:58" to jump down to the solution.

              When I had that it was was with PS4 controllers however, not PS4. I never had a PS3 so I don't know if they had similar, or any, motion sensors.

                No, and to remedy the motion control conflict, you should just install the sixaxis scriptmodule, as that will install a udev rule to blacklist the motion controls for both DS3 and DS4 controllers.

                Glad to hear it. If you want to avoid using an extra dongle, you could try reducing the baud rate even further (likely 230400) to potentially eliminate the errors entirely. The lower baud rate would impact usage of BT peripherals that need to transmit larger amounts of data, but if you're just using it for controllers, it might work OK.

                I have a suspicion that a kernel driver or Pi firmware update may have caused interference to get worse when flow control is not available, but I've never investigated this too thoroughly. My 3B exhibits this issue, but the workaround was effective enough for me to just leave it be.

                  I would agree that something has changed. I never had this problem when I was running Jessie. Same Pi, same controller. I only changed the SD card and installed the latest nightly. I didn’t update the firmware so maybe kernel.

                    Yes, agreed. After checking a related bug report, it seems that driver changes between kernel 4.14 to 4.19 may have exacerbated the issue.

                    Judging from the replies to that bug report, it looks as though reducing the baud rate even further (to 115200) may fully eliminate the dropped packets on the newer kernel releases.

                      Update on this issue: judging from recent comments in the bug report I mentioned in my previous post, a possible fix for the issue (which may have also affected boards with hardware flow control enabled) has been committed to the firmware via this commit.

                      You could test the fix via rpi-update, but I would generally discourage users from bypassing the Debian packaging of firmware packages by this tool. If you have a spare card and want to experiment on a test install, however, it could be worth a try. I'm not sure if/when I'll test, as I don't have a spare SD card at the moment.

                        Thanks mate, I don't have a spare SD at the moment either, but I might be able to give it a run in a few weeks.
