please add these patch to make ax210 bluetooth can work on jetson normaly  
why it dosen’t work  
because 5.10 (upstream) have issue with newer Bluetooth Firmware and that cause abnormal system load  
more info see in [https://community.intel.com/t5/Wireless/AX210-bluetooth-not-working-on-jetson-xavier-nx-on-linux-kernel/td-p/1447850](https://community.intel.com/t5/Wireless/AX210-bluetooth-not-working-on-jetson-xavier-nx-on-linux-kernel/td-p/1447850)

fix patchs is here [l4t-community / Kernel / t194 / kernel-5.10 · GitLab](https://gitlab.azka.li/l4t-community/kernel/t194/kernel-5.10)  
please pull that patch into nvidia l4t kernel if passible  
wifi patch is not fixed yet

5.15不需要使用這個修正  
因為5.15沒有這個問題

Azkali didn’t make it latest  
But if you know how to build kernel just replace what azkali edited

It worked on my Orin NX. Here is the solution:

1. Check linux kernel version: `uname -r.` If `<=5.11.xxx`, then you need the bluetooth patchwork.
2. Check L4T core version: `dpkg -l | grep 'nvidia-l4t-core'`, there should be `35.3.1-x` or `35.4.1-x`
3. Download the driver based on your L4T version:  
- `35.3.1-x`:[https://gitlab.com/l4t-community/kernel/t194/kernel-5.10/-/archive/jetson\_35.3.1\_ax210/kernel-5.10-jetson\_35.3.1\_ax210.zip?path=drivers/bluetooth](https://gitlab.com/l4t-community/kernel/t194/kernel-5.10/-/archive/jetson_35.3.1_ax210/kernel-5.10-jetson_35.3.1_ax210.zip?path=drivers/bluetooth)  
- `35.4.1-x`:[https://gitlab.com/l4t-community/kernel/t194/kernel-5.10/-/archive/jetson\_35.4.1\_ax210/kernel-5.10-jetson\_35.4.1\_ax210.zip?path=drivers/bluetooth](https://gitlab.com/l4t-community/kernel/t194/kernel-5.10/-/archive/jetson_35.4.1_ax210/kernel-5.10-jetson_35.4.1_ax210.zip?path=drivers/bluetooth)
4. Extract and enter `cd <your_unziped_file>/drivers/bluetooth`,
5. build the driver:

```auto
sudo make -C /lib/modules/$(uname -r)/build M=<your_unziped_file/drivers/bluetooth> modules

```

- If you see error at building like `error make: *** No rule to make target 'modules'. Stop.`, it means you have a wrong symbolic link to the linux kernel header. Here is my solution.

```auto
rm -rf /lib/modules/$(uname -r)/build # remove the wrong link
sudo ln -s /usr/src/<linux-headers-xxx>/<kernel-5.1.x>/ /lib/modules/$(uname -r)/build # create the right symbolic link to the right kernel header directory

```

1. Now you can see there are newly-compiled 13 `.ko` files in `<your_unziped_file/drivers/bluetooth>`. Copy them to the following directory: `lib/modules/$(uname -r)/kernel/drivers/bluetooth`, and rewrite the existing driver.
2. Reboot.
