Bluetooth with .... any other adapter fails

Hello. I am fighting to use this board. Expecially to let it work with the bluetooth services. The wiki page suggests to install the patch for the bluetooth services. I receive this erroro code trying to install it:

Setting up rockpi4-brcm-patch (0.1) ...
Failed to enable unit: File brcm-patch.service: No such file or directory
dpkg: error processing package rockpi4-brcm-patch (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 rockpi4-brcm-patch
E: Sub-process /usr/bin/dpkg returned an error code (1)

Second question: using the hard to manage bluetoothctrl cli interface I notice that all issues are the same for all the device that I insert in the usb ports!!! I have three different and well working USB adapters and none is still syncing with my headset. Radxa programmers, are you still there? Tok, Tok, can we use this SBC?
