Bluetooth and wifi is not working in android 10 imx8mm board

[shamiullah]

Hello @all

I am working on android 10 imx8mm board. Bluetooth and wifi is not working. When i am turning ON the bluetooth, it is showing "Bluetooth is stopping" and i am not  able to turn ON wifi too. With the same hardware, both wifi and bluetooth are working in android 11 but i am facing issues in android 10. Please let me know if any

Hi Igor,

I followed the document  you have shared but still i am facing the same issue.

Can you provide me the following information

•  In which file it is mentioned the path of Bluetooth and WiFi firmware's? I want to know which firmware does my board use?  Can you please provide the path of the above file?

Thanks & Regards
