@Zing thanks but isn't corrupted amigo, checking recalbox.conf i see missing bluetooth lines so i added them. Apparently if you delete all the connected peripherals the configuration in the file is also deleted... Now is fixed so problem resolved.
I still can't get it to work. I bought a different Bluetooth Stick (CSL nano V4), but same result: it finds the controller as "Pro controller", when selected it says "in progress" for a long time until the controller stops his pairing mode. Then it takes even some time for the message "unable to pair controller to appear.
I'm totally out of ideas. (said so before, I know)
@joe-berndt yes i have the pro switch controller ,it work on recalbox
1: go to the recalbox associate bluettoth controller
2: make a long press on the verry small button at left of usb (you listen a click)0_1584697079938_IMG_9326.JPG
3:press on associate a bluetooth controller at the same time as you press the small button (make a very long press on the small button)wait, your recalbox will have found bluettoth devices including one called pro controller press on it
4:your swith pro controller is detected go to configure controller and your controller is detected
ollow the instructions to configure a controller and your controller will therefore be operational (at each start of the recalbox (the recalbox must find the controller) you have to do a long press on the small button and go to configure a controller and it will appear
So: I tried to reinstall Recalbox 6.1.1 from scratch all over again. 8bitdo pairing suffering from the same problems (cant pair). Tried to pair manually via bluetoothctl, it WORKS - but does not keep paired after a reboot.
I honestly do not know what to do anymore. Cant find older version (6.0) anywhere anymore and 6.1.1 is useless for me if I cant keep my gamepads paired.
If someone have any solutions for this, please let me know.
@hunterln only God knows.
Recalbox is an entirely volunteer job, so a beta will be release when developers bring it to a state stable enough for general use. Before that it doesn't make any sense, because users would be complaining about stuff not working as expected. It is that simple.
