@rastabolino said in 8bitdo Arcade Stick - Bluetooth connection RT and LT issue:

RT: 5:-32767 when activated the "-" goes on and off
LT: 2:-32767 when activated the "-" goes on and off

Are you saying that when you watch the screen pressing nothing the value is -32767 and when you press the button it instantly changes to 32767 and you never see any numbers other than those two?

@redmarsbluemoon Yes, stock Raspbian. No need for userland ds4drv :) Imperceptible latency atlhough I've never measured it, I can easily play even games like Street Fighter II.

Try updating your packages/kernel? apt dist-upgrade and rpi-update.

Also be careful about interference from other wireless sources (Wi-Fi, other 2.4 GHz devices)... Maybe try moving things around and seeing if that helps. Best of luck.

I GOT IT WORKING!!!

Good Grief.....in the end I used the PS3 driver and what made ti work was, just after registering the device a window pops up saying you can now unplug your cable.

At this point, I unplugged and paired the controller and THEN with the keyboard moved back to the main menu to configure it.

Trying to pair the device at ANY other point during the process and it doesnt like it.

Have rebooted and the device still conect and works so it seems stable :D

Cheers for the help.

@lostless Got it, didn't realize I had to do this from Retroarch while playing the game. Thanks!!!

Ok, I finally managed to make the hotkeys work.

I needed to add the following section in /opt/retropie/configs/all/retroarch-joypads/8Bitdo_Pro_SF30_BT_B.cfg

#Hotkeys input_enable_hotkey_btn = "10" input_load_state_btn = "7" input_exit_emulator_btn = "11" input_reset_btn = "" input_save_state_btn = "6" input_menu_toggle_btn = "3" input_state_slot_increase_axis = "+0" input_state_slot_decrease_axis = "-0"

Problem solved!

Please post some details about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

All,

I have succeeded to set up the 8bitdo SF30 on RetroPie on the Raspberry Pi 4.

Here is the procedure I have have followed to make this work for me:

tested using a Raspberry Pie 4 4GB RAM with latest firmware

tested using RetroPie version November 12th 2020 / Github commit: 3d0a4ed7673e3d54aa5332d2894534fe00727c13 (cd ~/RetroPie-Setup/ && git show on the RetroPie over SSH) + any OS / RetroPie upgrades available at that date

tested with latest 8bitdo SF30 Pro firmware upgrade version 1.34

(once) update the controller firmware

download the latest SF30 firmware from 8bitdo website press simultaneously LEFT + RIGHT + start buttons on the controller: the front red light should be blinking plug-in the USB cable to the controller and the computer launch the firmware update executable 8Bitdo_Update_v1.10.exe click on the USB update button select the firmware file: Firmware_SF30&SN30_Pro_V1.34.dat once the upgrade completed, remove the USB cable

Bluetooth pairing (assumes that there is a working legacy controller like a the Buffalo wired controller I used for my tests to control the GUI while the 8bitdo controller is not set up yet).

boot on RetroPie on the Raspberry Pi 4 select RetroPie configuration menu select Bluetooth menu select Register and Connect to Bluetooth Device to trigger a device search start the controller by pressing start + B buttons click on the small grey pairing button, on the front side of the controller, above the select button, to pair the controller RetroPie should detect the controller and display its hexadecimal address click OK for the security mode prompt: select Keyboard only (this option, at least, seems OK and does not generate a connection error to the controller) select Setup udev rule for Joypad menu click OK leave the 8bitdo mapping hack menu to OFF as the firmware has been upgraded to latest version (as detailed above) click CANCEL then B button to exit RetroPie configuration / start button / QUIT / RESTART SYSTEM to reboot RetroPie when rebooting, the leftmost green light (of the four green lights at the back of the controller) should be blinking. When Emulationstation is up and running, the leftmost green light should stop blinking and remain green indicating that the controller is now paired with RetroPie and functional.

Configuring inputs of the controller in Emulationstation

click start button select CONFIGURE INPUT long press the A button to trigger the configuration press all relevant keys as prompted for the HOTKEY (last input to configure): as all keys / pads have been assigned, you can press either the little grey button just on the right of the right analog pad or the other button on the left of the left analog pad. Tests show that this may not allow to exit the emulator. You can press simultaneously the select and start buttons of another (wired) controller to exit an emulator if the HOTKEY on this controller does not work for that purpose.

Feel free to give your feedback on any clarifications or corrections, and I hope this helps.

Apparently this is an issue with the SN30 Pro itself. I got it working. Here's what I did:

Deleted /etc/udev/rules.d/99-bluetooth.rules Deleted SN30 Pro from registered Bluetooth devices Powered on SN30 Pro with Start+B (Android mode) and held Pair button (top of controller) for 3 secs to immediately go into pairing mode. While in pairing mode selected Register and Connect Bluetooth Devices in RetroPie-Setup Script >> Setup >> Configure Bluetooth Devices Selected 8Bitdo SN 30 Pro from list and finished config Did NOT set up udev rule

Now the controller is working perfectly; I'm able to open Launch Menu or go straight into games ... no sitting at black screen for ~40 secs. Also no waiting required to navigate script menus either.

I did have to reconfigure controller layout ... and the L/R triggers are actually recognized now as well.

@mitu said in Problems connecting bluetooth controllers:

Glad you found the solution, this issue will probably be fixed with the next Raspbian package update for the pi-bluetooth package.

Package has been updated, with the fix referenced in the Raspbian forums.

Drivers are usually not installed in the image, you have to install them - such is the xpadneo driver.

ok so that may not have been my problem but i did get it paired but the only change i did was for something else which was turning off hardware acceleration cause it would crash when trying to scroll through games. dont have any idea how there connected though. but after that paired just fine.

Awesome! This worked like a charm. Thank you!
