Adafruit feather and RetroPie

CeZza_Gant

Hello,
I've recently bought an Adafruit Feather 32u4 Bluefruit LE and got it set up to work like a keyboard, when I connect a GPIO pin it types a letter. I can successfully connect to RetroPie but when I try to configure input the feather doesn't show up, Can anyone tell me whats going on?

@cezza_gant Have you installed any drivers? You probably need gamecondriver Install this via the setup script.

@jonnykesh I think gamecondriver works for controllers connected to the Raspberry pie's GPIO, I'm trying to connect via Bluetooth rather than physically.

@cezza_gant Sorry, I have no idea what the feather is. Have heard of it, just never bothered to find out what it actually is and since you mentioned GPIO I just assumed.
What is it?

@jonnykesh The feather 32u4 Bluefruit is basically a microcontroller board with Bluetooth capabilities. The idea is to solder some buttons on to it and make myself a Bluetooth controller. https://learn.adafruit.com/adafruit-feather-32u4-bluefruit-le/overview

@cezza_gant Sorry, yeah just googled it. Seems like you are not the only one having issues. https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=170499&p=1093659

Phiuuu.... I had the same problem @CeZza_Gant .

First i updated BlueZ to version 5.37 from this link

https://learn.adafruit.com/install-bluez-on-the-raspberry-pi/installation

There's a newer version (5.47 or something) but when i installed that one it didn't work.

Anyway... after following the instuctions for 5.37 suddenly it worked. Not sure what happened but it worked.

Turn On my Adafruit Feather 32u4 Bluefruit LE
I entered to configuration ->bluetooth->Register and connect
Retropie detects my BLE device and then connects
Something happens there, the UI freezes so i have another keyboard connected to my RPi, Ctrl+C to go back to Emulation Station
And that's it. The feather's blue LED is turned on and connected to the RPi
You go to configure input and the feather is detected as a keyboard.

It all was a trial and error, so, if my instructions doesn;t work, keep trying.

Regards from Mexico!
