Bluetooth Problem - H96 Max RK3399 - Wifi QCA9377 Works

[rna]

Dear All,

I have a problem with fixing my Internal Bluetooth Driver using H96 Max RK3399, Just to let you know that Wifi Driver QCA9377 (ath10k) is working out of the box using the latest Manjaro stable kernel 5.10.8. But the Bluetooth is not working.

I have asked on Arm Forum, but as per @SickOS suggestion, this problem is not specific to Arm. Therefore General Forum might be able to answer the problem. Here’s the post:

Manjaro ARM for Rockchip TV Boxes

Ok Rfkill reports is not blocked so no problems there but radio is not up. From second report seems you have rtl, Intel, qca and bcm drivers too many for just a device. Only last two could work. Kill rtl and Intel if you know howto but better ask for support in general forum as this is not arm specific and I don’t know how to proceed.

Here’s the result of several test:

$ rfkill list
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

According to @SickOS, I need to kill the driver that is not needed, like rtl, intel and etc. But I don’t know how to do that?

Could someone please help me?

Many Thanks

When pasting terminal output, use the Preformatted text </> button, not the Quote " button please.

The thing is, when I used the code, it just work for the first line, the rest cannot work. But with quote, all lines are recognized as one. Just now I changed it with your suggestion, but it broke the format that I want.

[Yochanan]

That’s because you pressed the button without highlighting the text first. It just adds four spaces indenting the text.

An alternative is three backticks ` above and below the text:

```
text
```

Yes, this one works very well, this is what I was looking for. But, because I couldn’t find it in the icon above, therefore I use quote. Many thanks for this info. Now I can format code properly and easily on Manjaro Forum.

I fix this bluetooth issue with the help from @SickOS and this Github Link: Search · QCA9377 · GitHub

To see my detail process you can see my post on Manjaro Arm section:

Manjaro ARM for Rockchip TV Boxes

@SickOS You are amazing…!!! Many Thanks for your link, finally I figure it out how to fix the Bluetooth. The answer is I have to change the dtb to dts, and then replace the bluetooth compatibility into this: bluetooth { compatible = “qcom,qca9377-bt”; Now Bluetooth is working perfectly on my H96 Max - RK3399 Box. Here’s the step by step: Convert the working dtb into dts (In my case the best working dtb is rk3399-rockpro64.dtb): dtc -I dtb -O dts /your/dtb/location/rk3399-rockpro64.dtb…

Or the easiest way, you can download my dtb from this Armbian Forum: https://forum.armbian.com/topic/17223-bluetooth-is-not-working-h96-max-rk3399/?do=findComment&comment=121073

Then copy paste those dtb to your dtb folder, then change your configuration text to that dtb. Then Restart your box. Bluetooth should work out of the Box.

Hope that helps!
Many Thanks,
