Bluetooth CSR8510 not working with Rock64 Android 7.1

[geno]

I use my rock64 as a 4k media center AND as a retro console. for the latter i need a playstation 4 pad connected via bluetooth at best. I have the rock64 now for about a year and unfortunately I still have to connect my controller via a cable with the rock64 to play. Accordingly, I can not use the device for this purpose virtually. Unfortunately. because the rock is a super console with retro arch. in any case, if you could connect his pad with bluetooth.

if anyone finds a bluetooth solution for an android version i would be very happy.
