Thanks very much for your answer about how to workaround that issue, I do manual pairing using bluetoothctl and work.
I also checked the topic you mentioned (https://forum.recalbox.com/topic/12090/utilisation-bluetooth-sur-odroid-xu4/50), and I did the suggestion that @bdemonte commented #48 from that thread.
I adjusted the file named 'test-discovery', then restarted and voila, I am able to discover and pair the 8Bitdo controller from the ES!! :)
I think that this adjustment is going to be merged in the future, so it will be fixed.
Thanks very much for your comments and support!!
