Bluetooth is not working - H96 Max RK3399

[rna]

Dear All,

I managed to install Armbian on my H96 Max RK3399 box by using the nano-pc-t4 image Armbian Focal, and rockpro64 dtb.
I am also able to boot to Armbian Twister OS by using Armbian Reforge u-boot as I mentioned in my previous post:

Everything works fine. Even I managed to activate the internal wifi QCA9377 (ath10k_sdio) by installing the Full Armbian Firmware via armbian-config.

I also installed the bluetooth module via armbian-config. The buetooth status is active But the bluetooth is not working.

$ service bluetooth status

The systmctl indicates that bluetooth is running

$ systemctl | grep -i bluetooth
  sys-devices-platform-ff180000.serial-serial0-serial0\x2d0-bluetooth-hci0.device               loaded active plugged   /sys/devices/platform/ff180000.serial/serial0/serial0-0/bluetooth/hci0

  bluetooth.target                                                                              loaded active active    Bluetooth

 

But dmesg cannot detect the hardware

$ dmesg |grep -i Bluetooth
[   31.934540] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[   31.934552] Bluetooth: BNEP filters: protocol multicast
[   31.934572] Bluetooth: BNEP socket layer initialized

 

Bluetoothctl cannot find the hardware

 

$ bluetoothctl
Agent registered
[bluetooth]# power on
No default controller available
[bluetooth]# scan on

[bluetooth]# 

Did anyone has experience the same problem? How to setup bluetooth on Armbian Focal? How to solve this problem?
Many Thanks for your help

I will answer my question myself:

I solved this issue with help from @sickOS from Manjaro forum and this link: https://github.com/maz-1/h96-pro-plus-armbian-stuff/search?q=QCA9377

For the detail of step by step you can see my post on Manjaro forum here: https://forum.manjaro.org/t/manjaro-arm-for-rockchip-tv-boxes/44998/55
 

But for those of you that need the dtb (I edited the "rk3399-rockpro64.dtb" bluetooth section) you can find it here:

rk3399-H96Max.dtb rk3399-H96Max.dts
 

 

It's simple, just copy and paste my "rk3399-H96Max.dtb" into your dtb folder, then change your configuration text to this new dtb. Then restart your box. Your Wifi and Bluetooth should work out of the box. But please make sure that you have installed armbian-full-firmware from armbian-config.

Hope that Helps!

Many Thanks,
