There is a perfect link here describing the problem
Want I want is the following Bluetooth firmware added for support for certain 5.0 dongles.

- https://raw.githubusercontent.com/Realtek-OpenSource/android_hardware_realtek/rtk1395/bt/rtkbt/Firmware/BT/rtl8761b_fw
Under /lib/firmware/rtl_bt/
I have added them by my self but it would be nice if batocera would include them by default.
Thank you for your time
