Xbox Core Bluetooth Controller, RetroPie 4.7.1, Pi 4 - not working

[Al 0]

Hi everyone.

I have an Xbox Core Bluetooth controller that I use for Apple Arcade and would like to use it for my RetroPie setup but am having some issues.

Pi Model: Pi 4, 8GB
Power Supply used: From this CanaKit.
RetroPie Version Used: retropie-buster-4.7.1-rpi4_400.img
Built From: balenaEtcher on Windows 10
USB Devices connected: Microsoft Wireless Keyboard + Mouse

Steps:

1. Boot up first time
2. Configure keyboard
3. Follow this guide to disable ERTM:

• I verify no devices are connected.
• I get all the way to selecting the Xbox Controller that it discovered.
• I do NOT get the "Successfully registered and connected to <device ID>" dialogue.
• I do NOT get an error message of any kind.
• I simply get dumped back into the "Configure Bluetooth Devices" screen.
• But it does show up in the "Registered Devices" page, identified as "Xbox Wireless Controller 4416".
• Despite that, the controller is still blinking.

However, when I go to Configure Input, there are no gamepads detected.

I've rebuilt the device 2x from scratch, same results.

UPDATE: I tried the "Connect now to all registered devices" option and after a couple seconds this error message flashed (very quickly) on the screen:

/home/pi/RetroPie-Setup/scriptmodules/supplementary/bluetooth.sh: line 329: Connecting: command not found

At a loss here. Appreciate any further help?

Cheers!
Al

There's an Xbox specific driver (xpadneo) that might help connecting your controller. Try installing the driver first from the RetroPie drivers section.

@mitu, greatly appreciate the reply and option. Thank-you!

It's probably a little over my head, but I'll dig in a bit.
