Bluetooth Audio Setup

This guide shows how to enable Bluetooth audio on Jetson and connect a Bluetooth speaker or headset. It covers required drivers, service configuration changes, and installing the necessary audio modules.

Connecting a Bluetooth Speaker

The Jetson Nano 2GB Developer Kit does not have built-in Bluetooth. To connect a Bluetooth audio device to the Developer Kit, you need to use a USB Bluetooth adapter.

Follow the steps below to enable Bluetooth audio on the Developer Kit.

Bluetooth Adapter Requirements

The Bluetooth adapter must support the Linux operating system, and you need to have access to the drivers for the Bluetooth adapter.

Connecting Bluetooth Audio

Install any required drivers for the Bluetooth adapter on the Developer Kit. Follow the instructions from the Bluetooth adapter manufacturer.

After installing the drivers, you may have to restart the Developer Kit for the system to enable it.
Connect the Bluetooth adapter (if you did not connect it while installing the drivers)

Navigate to this file:

/lib/systemd/system/bluetooth.service.d/nv-bluetooth-service.conf

Use a text editor to change this line...
```
ExecStart=/usr/lib/bluetooth/bluetoothd -d --noplugin=audio,a2dp,avrcp
```
to the following content:
```
ExecStart=/usr/lib/bluetooth/bluetoothd -d
```
That is, remove the ‑‑noplugin switch and all its values.
Enter these commands in the terminal to update the package list and install the PulseAudio package:
```
$ sudo apt-get 更新
$ sudo apt-get install pulseaudio-module-bluetooth
```
Enter this command to restart the Jetson device:
```
$ sudo reboot
```
After the restart is complete, pair and connect any Bluetooth headphones/speakers

LXPanel Menu -> Preferences -> Bluetooth Manager
