Connect to Bluetooth Device via Command Line in Ubuntu

Ubuntu 3

In this article, we will be exploring how to connect to a Bluetooth device via the command line in Ubuntu. This can be particularly useful for system administrators and developers who prefer to work in a terminal environment or for scripting purposes.

Quick Answer

To connect to a Bluetooth device via the command line in Ubuntu, you can use the bluetoothctl tool. First, install the bluez package using sudo apt-get install bluez. Then launch bluetoothctl by typing bluetoothctl in the terminal. Use the devices command to list the paired devices, and the connect command followed by the device’s MAC address to establish a connection. Verify the connection using the info command. If you encounter any issues, ensure the device is in range, turned on, and in pairing mode.

Introduction to Bluetoothctl

The primary tool we will be using is bluetoothctl, which is a part of the bluez package in Ubuntu. bluetoothctl is a command line utility for pairing, connecting, and managing Bluetooth devices. You can install it using the following command:

sudo apt-get install bluez

Launching Bluetoothctl

To start the bluetoothctl interactive prompt, open your terminal and type:

bluetoothctl

This will change your terminal prompt to [bluetooth]#.

Listing Paired Devices

Once inside the bluetoothctl prompt, you can list the paired devices by typing:

devices

This command will display a list of all paired Bluetooth devices, along with their MAC addresses. The MAC address is a unique identifier for the device, which we will use to connect to it.

Connecting to a Device

To connect to a device, use the connect command followed by the MAC address of the device. Replace XX:XX:XX:XX:XX:XX with the MAC address of your device:

connect XX:XX:XX:XX:XX:XX

This command will attempt to establish a connection with the specified device.

Verifying the Connection

To verify whether the connection was successful, use the info command followed by the MAC address of the device:

info XX:XX:XX:XX:XX:XX

This command will display detailed information about the device, including its connection status. If the connection was successful, you should see Connected: yes in the output.

Troubleshooting

If the connection fails, make sure the device is in range, turned on, and in pairing mode. If you’re still having trouble, you may need to pair the device first. You can do this with the pair command, followed by the device’s MAC address:

pair XX:XX:XX:XX:XX:XX

Conclusion

The bluetoothctl tool provides a powerful command-line interface for managing Bluetooth connections in Ubuntu. By understanding how to use this tool, you can connect to Bluetooth devices directly from the command line, providing a versatile solution for many different use cases.

For more information on bluetoothctl and its various commands, you can check the man page by typing man bluetoothctl in your terminal, or visit the official BlueZ documentation.

Remember, while the command line can be powerful, always ensure you understand the commands you are running. Happy coding!
