Switch joy con for mouse/keybord inputs

[Jason554]

Hi, im exploring whether I can use my switch joycon for mouse/keyboard inputs following the steps in hid-remapper/BLUETOOTH.md at master · jfedor2/hid-remapper · GitHub

1. I’m not finding any references to pairing a switch joycon to one of these boards or whether its supported. I have the feeling that these will only support other bluetooth mouse/keyboards for remapping and not a switch joycon?
2. If not, are you aware of any references which could allow this functionality? Im aware of software solutions but Im ideally wanting for HID input.
3. I have a feather rp2040 but as far as im aware I dont think I could connect the joycons through it even with a bluetooth dongle, perhaps any other controller (ps5 or xbox) connected by USB could work?

Switch 1 joycons use Bluetooth Classic so they won’t work with the nRF52840 based Bluetooth version.

They might work with this, but I haven’t tried:

Bluetooth Classic version testing (Pico W)

Please note this is experimental and there’s a non-zero chance it will end up getting scrapped. (However, unlike the ESP32 version, you should be able to use it for commercial purposes with no additional license: it uses the same component, but Raspberry Pi paid for the license for you.) I’ve been experimenting with a Pico W-based version of HID Remapper that supports Bluetooth Classic devices (the previously existing nRF52840-based version only supports Bluetooth LE). There are currently two…

If they worked, you’d be able to remap them to anything like with any other device.

How about the switch 2 joycons? From another post they appear to not use bluetooth classic.

Could I then configure the switch 2 joycons through following hid-remapper/BLUETOOTH.md at master · jfedor2/hid-remapper · GitHub ?

Switch 2 joycons use Bluetooth LE, which is the standard that the nRF52840 supports, but as far as I know they are not standard HID devices and use a proprietary vendor protocol instead, so they will not work.
