I am using jetson xavier nx devkit. It is showing “No Bluetooth adapters found” while selecting bluetooth option. How to check whether there is Wifi+BT module connect on M.2 E key slot? Shall I connect extra bluetooth adapter for getting bluetooth connectivity to jetson xavier nx devkit.

Hi,
You can run the command to check if the module is connected:

$ lspci -v

My lpci -v gives above result

Hi,
The module is not inserted to Key E slot. If it is inserted, you will see like:

Hi,
If you use Xavier NX developer kit, it shall have the module in Key-E slot. Probably it’s removed. You may buy a module and give it a try.
