Bluetooth is not working on X96MaxPlus_2101

[drafort]

Model: X96MaxPlus_2101
WiFi & Bluetooth chip: FN-LINK 6222B (rtl88x2cs)

Armbian: Armbian 23.02.0-trunk Jammy with Linux 6.1.12-flippy-82+
Booting from sdcard
Bluetooth already installed from armbian-config, but no Bluetooth devices found, however, on installed ("from the box") at emmc Android 9, Bluetooth working perfectly.

Thank you to reply!
Dtb changed as pointed.
Still no Bluetooth devices available

armbian-config > Network > Install Bluetooth Support

[drafort]

Or it's important to change Linux kernel to 5.15 from 6.1? And to use Jammy 5.15.94?

[ophub]

https:/ophub/kernel/tree/main/pub/stable

This dtb is available in four series (5.4/5.10/5.15/6.1) kernels. You can switch freely

armbian-update -k 5.x.y

[drafort]

armbian-config > Network > Install Bluetooth Support

already been installed
no devices found

[ophub]

Update other series of kernels to see which can drive

[drafort]

Update other series of kernels to see which can drive

Thanks!
I'm trying now and will give feedback here

[drafort]

Update other series of kernels to see which can drive

Kernel was updated to 5.15.94 using armbian-update -k
Still no Bluetooth devices found.
Bluetooth support is installed from armbian-config.

[drafort]

Kernel downgraded to 5.10.168
But still no Bluetooth devices found

[drafort]

Kernel was downgraded to 5.4.231
But result is the same: no Bluetooth devices found. What to do?

[drafort]

upd:
Tried to use Debian bullseye 5.15.94 instead Ubuntu (usb flash drive and sd card)
System is not booting up with dtb "meson .... max_plus" and "meson .... max_plus_100".
Successfully started with "meson .... x96_air_1000", but still no Bluetooth devices found (Bluetooth support was installed from debian-config).
May be problem is in dtb?

[ophub]

unifreq/linux-5.15.y@d1a5aff

This driver is added by a third party, some people can use it, some people can't, it's unstable.
Give up if the test fails, there is no other way at present.

[drafort]

Found this:
https://forum.armbian.com/topic/25334-need-correct-dtb-for-rtl8822cs/
May be helpful

[salsabilng]

I have same tv box, im able to edit the dtb to activate the bluetooth. currently using 6.1.12 kernel

here is my dtb, extract, then replace meson-sm1-x96-max-plus.dtb in /boot/dtb/amlogic
dont know yet if it's stable or not, but it works on me

meson-sm1-x96-max-plus.zip

[drafort]

Thank you!
It's more better, but errors occurred.

May be I do something wrong?

ps. Bluetooth support was installed from armbian-config

[salsabilng]

maybe driver issue, not sure, try another kernel.
try to use it first, if it works, u can just ignore it

[drafort]

maybe driver issue, not sure, try another kernel. try to use it first, if it works, u can just ignore it

not working: no device

now I'm trying with Ubuntu 6.1 instead Debian 6.1

[salsabilng]

sudo rfkill , see if the bt device listed

[drafort]

sudo rfkill , see if the bt device listed

yes, it listed

[salsabilng]

sorry, dont know much, try to change the kernel

[drafort]

sorry, dont know much, try to change the kernel

Thank you! I'll try and leave feedback

[drafort]

Kernel was downgraded to 5.15.94
hci0 is disappeared from rfkill list(
Bluetooth support is installed from armbian-config

[salsabilng]

you need to replace the dtb again.

[drafort]

you need to replace the dtb again.

cannot start system (deb 5.15.94) with this dtb

[drafort]

I think that's driver problem. May be possible to inject to dtb this driver?https://codeberg.org/Hiyurigi/rtl88x2cs

[salsabilng]

hmm, try using bullseye 6.1.12

[salsabilng]

and use sudo bluetoothctl

[drafort]

hmm, try using bullseye 6.1.12

Already tryed, used "bluetoothctl" from root.
(see upper).

Or it's important to execute "bluetoothctl" from root with "sudo"?

[salsabilng]

'vei compiled new dtb, try this one

[ophub]

Can Bluetooth of rtl8822cs be used? Which dtb are you using?
cat /boot/uEnv.txt

[salsabilng]

i have changes the dts, so the bluetooth can be recognized. this is mine

personally, i never use the bluetooth, so i dont know will it works for transfering file or just streaming a music via bluetooth. The bluetooth can discover my other device and pair to it.

[salsabilng]

some changes i've made

unifreq/linux-5.15.y@main...salsabilng:linux-5.15.y:main

[salsabilng]

by the way, ive tried many times using usb with 5.15.y kernel and older on this box, and never succeed to boot. so use 6.1.y kernel only for usb uses.
in my case, i installed the armbian into emmc, and using the mainline boot, then i can get any kernel version working,

Thanks! I tested 6.1.

It's still no success.

ps. 5.15. successfully started with dtb from X96-air-1000

i suspect because your not using mainline uboot, but eh i'm not sure

[salsabilng]

just a few hours ago, chewitt add new dts to support banana pi that has RTL8822CS, although it has different cpu, may be we can adopt the bluetooth part to the x96 max plus dts. currently i cant do it myself because i have many homework.
@ophub @drafort

chewitt/linux@dc15871

this is what i already adopted

chewitt/linux@bbf2bea

[salsabilng]

i've done the changes if you still concern here is the step i through

1. i use dev 6.1.13 kernel, to get this run armbian-update -k 6.1.13 -v dev if you want you can try mainline boot, add -m yes in that command
2. replace dtb meson-sm1-x96-max-plus.dtb with this compiled dtb https:/salsabilng/amlogic-s9xxx-armbian/releases/download/kernel_5.15.95/5.15.95.tar.gz
3. reboot and good luck

[salsabilng]

I've added new dtb called meson-sm1-x96-max-plus-2101.dts, this will enable the rtl8822cs bluetooth and the Wifi on 2101 box. The Wifi are stable and show no error. I have open PR on unifreq 6.1. hope it will accepted soon

unifreq/linux-6.1.y#13

[ophub]

I left a message for him. You submitted this dts to 5.15 and the other three lts kernels

[drafort]

I'm sorry for the delay.
Thank you for help!
I'll make test today and will leave feedback

[drafort]

Result for me:
(kernel was updated without adding "-m yes", dtb was used as attached - for "max_plus" )

As I see: no Bluetooth devices.

[salsabilng]

I left a message for him. You submitted this dts to 5.15 and the other three lts kernels

thanks! will do,

[salsabilng]

im able to reproduce your error, it turns out only boot from emmc works. so you need to install it to emmc

[drafort]

Hello!
Is it possible to inform then "meson-sm1-x96-max-plus-2101.dts" will be included in "iso" release?

[ophub]

Can bluetooth and wireless work normally?

[salsabilng]

havent tried bluetooth for transfer any files, but it can pair and discover any device. for wireless, i have decrease the max frequency, little slow but stable for couple days now

[salsabilng]

recall that i use 6.1.y kernel,

[ophub]

You submitted this dts to 5.4/5.10/5.15 kernels

[salsabilng]

done. waiting for approval. thanks!

[drafort]

As I understand it, Bluetooth will work only when system installed on EMMC. To install on EMMC, you must specify the type of device from "armbian-install" menu. Now 2101 is not specified in device list.
Now I tested to run 6.1 (ophub) form usb with 2101.dtb from salsabilng. In rfkill hci0 is listed, but in "hcitool dev" - no devices.

[salsabilng]

armbian-install , select x96-max-plus. then copy 2101 dtb to /boot/dtb/amlogic . edit uEnv.txt change line to FDT=/dtb/amlogic/meson-sm1-x96-max-plus-2101.dtb

[salsabilng]

i have question @ophub, whats the difference between usb and mmc boot process, why the bluetooth only works in mmc?

[ophub]

The u-boot boot sequence is different.
Generally, the situation encountered is the opposite of yours. It is normal to start and use it on the usb, but it cannot be used when writing to emmc. You have filled in the blank again.

Don't forget to submit your dts to the internal kernel library. Because other kernels don't have it, you can't add this option to the default installation list. Otherwise, other kernels can't use it because they don't have a dtb.

[drafort]

Thank you!
However, is it possible to make Bluetooth work when booting from usb in the near future? Because now I need to have two systems: Android on emmc and armbian on usb.
