      Hi, I'm hoping someone can help me with a specific issue I'm having.

      I have a bluetooth le (aka low energy, bluetooth smart, bluetooth 4.0) keyboard that I have connected, paired and trusted on my pi. I can find it, register it and connect to it in the bluetooth menu of retropie, but it doesn't show up when I go to configure input, nor does it type anything if I F4 out to the command line.

      The same keyboard works fine with OSX and my iPhone as a keyboard. Is this a raspbian issue? How does retropie handle inputs?

      Thanks for any advice!

      Pi Model 3
      Power Supply used: the official one
      RetroPie Version Used: 4.1

      Keyboard is made with an Adafruit blue fruit 32u4 bluetooth le device

        Built a custom controller using the same Feather from Adafruit. I reached out on the Adafruit Forums and they think its most likely due to the BLE protocols not being supported in RetroPie. "BLE protocols differ from standard BT." So I think the question is, can anyone confirm that BLE is not supported by RetroPie and if its not, is there a way to make it work? I'm pretty ignorant when it comes to BT/BLE so any direction or help would be appreciated.

        Sorry I don't have the actual solution. Just wanted to provide what I knew...

          Hello,

          Sorry to revive a old topic but I have the same issue, and so I thought I'd add my details in case anyone has more info since last time:

          • Raspberry PI 3B
          • Retropie 4.3
          • BLE Keyboard Logitech K830

          As OP, the keyboard is discovered and it claim pairing is successful, but it's not usable :(.

          I found the post below on stack Exchange that looks promising (suggesting installing latest BlueZ module), but before I attempt the steps myself, I wanted to check if anyone has tried it for retropie.

          Thanks!
