Cubietruck Bluetooth with mainline kernel

[phelum]

Hi,

I'm trying to get Bluetooth working on a Cubietruck running 6.6 kernels including the latest Armbian release.  What I'm finding is that a Cubietruck can discover other Cubietrucks but nothing else.  Other devices (e.g. Raspberry Pi, Nvidia, Rockpi, and various phones) can discover each other but not the Cubietrucks.  I have three Cubietrucks here and testing with the old 4.99 Bluetooth software or the current 5.55 release shows no difference.  But if I run a Cubietruck with the ancient 3.4 kernel it can detect other devices but not the Cubietrucks running the 6.6 kernels.  I'm using the same Wi-Fi firmware and BT .hcd file in all cases.  So it's like the Cubietrucks with 6.6 kernels run Bluetooth in their own separate little world.

 

Has anybody managed to get AP6210 Bluetooth working properly with a mainline kernel ?  If so do you have any clues about how I can rectify this problem ?

 

Thanks,

Steven
