I have the A95X F3 Air 2 with a S905W2 processor and 2/16 GB.
It comes with Android TV 11 installed and has working bluetooth in it.
I am running CoreElec Omega 21 from microSD , Amlogic-ne with s4_s905w2_2g and everything except bluetooth works. I searched a bit but couldn’t find an obvious cause or solution.
lsusb doesn’t show a device :
CoreELECA95X:~ # lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
I don’t see much bluetooth related in the kernel output:
CoreELECA95X:~ # dmesg | grep -i blu
[ 12.291512@3] Bluetooth: bt_init: Core ver 2.22
CoreELECA95X:~ # dmesg | grep -i bt

I also noticed :
[ 1.612857@1] aml_aucpu aucpu: Direct firmware load for aucpu_fw.bin failed with error -2
[ 1.612869@1] load aucpu_fw.bin fail
[ 1.612874@1] load start_aucpu_fw fail
Not sure if it is related, I tried to load : vendor/lib/firmware/aucpu_fw.bin · soul-user-11-RTT0.211222.001-1440-release-keys · Android Dumps / xiaomi / soul · GitLab by putting it in /usr/lib/firmware but it made no difference and after that I saw the file is in /vendor/lib/firmware.

No change likely because no device exists to match.
I saw here someone else posting the same:
I will try the other builds and nightlies and report.
If anyone has a solution, please share, thank you!
