One thing that Iv'e read should improve (some)things is editing this file,

sudo nano /etc/systemd/system/bluetooth.target.wants/bluetooth.service

look for a line like the following and make it like below.
(maybe make a backup copy of the file first if you want)

ExecStart=/usr/lib/bluetooth/bluetoothd --noplugin=sap

Iv'e been messing around with RPi4 bluetooth and my DS4 controllers recently and that is now part of my setup steps.

@rafaz182 having the same issue with 4.7.1. Downgraded to 4.6 with a new flash but stopped working after doing an "apt upgrade" on 4.6 - did this fix you posted worked on 4.7.1?

@theotherdan said in SN30 Pro - Lag Problem with the SN30 pro:

The issue with the case was no shielding on the USB3 chip (As per the RetroFlag support). If the SSD adapter was plugged into the USB3 port, there was a range of about 3 feet. When I used the USB2 port, it worked as expected.

I feel it is worth adding to this.
I recently bought a plugable bluetooth adapter to add to an older PC that didn't have built in bluetooth. The packaging specifically said to plug the adapter into a USB 2.0 port instead of a USB 3.0 port to increase range.

I was puzzled by this but sure enough it is true. Here is a page that helps explain a little:

So best advice is to always use USB 2.0 ports for bluetooth, and possibly wireless devices in general when possible provided the device won't exceed the speed of a USB 2.0 port.

Please add some more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

What emulator/game are you starting ? The libretro emulators (starting lr-) should be auto-configured after you set-up the gamepad in EmulationStation, but if it's one of the other stand-alone emulators, additional configuration may be needed.

@mitu I did remove all connected / paired devices several times. I did also reset ES_input file. Nothing worked. Always when I try to pair it, it gives me error message, that device is already registered. The same with udev.

@mitu My apologies, I'm sorry. That wasn't I'm intent. Thank you.

Does anyone know if there is there any resolution to getting ALL of the buttons on this controller to work in ES? I'm disappointed that all of the buttons cannot be used. Originally I was attempting the macOS pairing and nothing would work (I read somewhere this is the best setting for retroarch. Cannot cite my current source because I forgot).

After two weeks of trial and error, I'm happier after reading this thread that I can use the Windows setting, but I often use the trigger buttons for load and save states (the shoulders are for ff and rewind). So full functionality is reduced for me.

@pierouge in which Mode did you connect your 8biDo? Switch, Android, Mac or Win?
I just learned that this is an important point and after a change (Android. Start+B) my Pads work perfect.

@r3lic Glad you got it sorted out, all credit goes to @meleu for his script.

I've been having issues with the sensitive dpad, but after tinkering with tape I can reliably duck and run with Mario, but throwing a Haduken with Ryu is less than reliable. I wonder if these rings provide the best of both. I'll try it as soon as I can.

@Impman66 how you set up your speedlink controller? I have SL-6566-BK xeox pro analog gamepad-wireless-black, retropie detected it but when i press&hold A to set up nothing happened.. please help

@caver01 said in 8Bitdo -> checking firmware version ?:

@jeffjordan Well, none of us here can really speak to the quality/effectiveness of their flashing utility. ....

Of course not !
this is a retropie related forum and my question was "at the edge" of being off-topic.
just wanted to inform other users with my reply about the curious behaviour.
and yes: you need to get into the mode where you can flash the pad, you need to press <power> & <pair> for a few seconds, until the pad led's flash yellow; afterwards you can connect the pad to the usb port...

Off topic warning: Could not find a way to PM you, hope it’s OK that I ask you here instead!

I have a 8Bitdo Arcade Stick, and have Bluetooth problems with it on Retropie. When pushing a direction and pressing a button, multiple presses are registered in Retropie. Just curious if yours is working fine, and if you know what firmware you have installed? Thanks!
