# Bluetooth 1. **Launch bluetoothctl**: Type `bluetoothctl` and press Enter. This will open the Bluetooth control prompt, indicated by `[bluetooth]#`. 2. **Turn on Bluetooth**: To ensure Bluetooth is powered on, type: ```csharp power on ``` 3. **Make the Device Discoverable**: If you want to make your Raspberry Pi discoverable by other devices, type: ```csharp discoverable on ``` 4. **Scan for Devices**: To start scanning for nearby Bluetooth devices, type: ```csharp scan on ``` You will see a list of available devices and their MAC addresses. 5. **Pair a Device**: Once you find the device you want to pair with (for example, your Bluetooth mouse), pair it using its MAC address: ```arduino pair [DEVICE MAC ADDRESS] ``` Replace `[DEVICE MAC ADDRESS]` with the actual address of the device. 6. **Connect to the Device**: After pairing, you’ll need to connect to the device: ```arduino connect [DEVICE MAC ADDRESS] ``` 7. **Trust the Device (Optional)**: To automatically connect to the device in the future, you might want to trust it: ```css trust [DEVICE MAC ADDRESS] ``` 8. **Stop Scanning**: Once you're done, you can turn off scanning: ```vbnet scan off ``` 9. **Exit bluetoothctl**: Type `exit` to leave the bluetoothctl prompt. Additional Commands: * **Show Devices**: To list all known devices, use: ``` devices ``` * **Show Paired Devices**: To list paired devices, use: ``` paired-devices ``` * **Remove a Device**: To remove/unpair a device, use: ```arduino remove [DEVICE MAC ADDRESS] ``` * **Show Info**: For information about a specific device, use: ```css info [DEVICE MAC ADDRESS] ``` This should cover most of the basic usage scenarios for `bluetoothctl`. Remember, for specific devices (like some headphones or speakers), additional steps might be required for full functionality. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
