The Bluetooth config options are: Enabled, Pairing Mode and Fixed PIN Value.  Bluetooth config uses an admin message sending a `Config.Bluetooth` protobuf.

:::info
ESP32 Devices: Bluetooth will be disabled if WiFi is enabled. The WiFi setting takes precedence.

## Bluetooth Config Values

### Enabled

Enables Bluetooth.

### Pairing Mode

Specify pairing mode.

`RANDOM_PIN` generates a random PIN during runtime.
`FIXED_PIN` uses the fixed PIN that should then be additionally specified.
Finally, `NO_PIN` disables PIN authentication.

### Fixed PIN

If your pairing mode is set to `FIXED_PIN`, the default value is 123456. For all other pairing modes, this number is ignored. A custom integer (6 digits) can be set via the Bluetooth config options.

### Default Pairing Mode

The default pairing mode will be determined based on whether the device has or does not have a screen attached to it during the first boot (or with a stale device state) unless manually configured via the Bluetooth config options.

- **Screen Attached:** If your device boots up for the first time (or with a stale device state), and a screen is detected, the default pairing mode will be set to `RANDOM_PIN`. Should the attached screen be removed after the device has already been booted, the default pairing mode of `RANDOM_PIN` will remain unless manually changed to `FIXED_PIN` or `NO_PIN`. It is recommended the pairing mode be updated prior to removing the attached screen.
- **No Screen Attached:** If your device boots up for the first time (or with a stale device state), and no screen is detected, the default paring mode will be set to `FIXED_PIN` with the aforementioned default value unless manually configured to a custom value.

:::info

All Bluetooth module config options are available in the python CLI. Example commands are below:

:::

|          Setting          |  Acceptable Values  | Default |
| :-----------------------: | :-----------------: | :-----: |
| `bluetooth.enabled`       | `true`, `false`     | `true` |
| `bluetooth.mode`          | `RANDOM_PIN`, `FIXED_PIN`, `NO_PIN` | `RANDOM_PIN` |
| `bluetooth.fixedPin`      | `integer` (6 digits) | `123456` |

:::tip

Because the device will reboot after each command is sent via CLI, it is recommended when setting multiple values in a config section that commands be chained together as one.

```shell title="Example:"
meshtastic --set bluetooth.enabled true  --set bluetooth.fixed_pin 111111
```

:::

```shell title="Enable/Disable Bluetooth Module"
meshtastic --set bluetooth.enabled true
meshtastic --set bluetooth.enabled false
```

```shell title="Set a fixed pin"
meshtastic --set bluetooth.mode FIXED_PIN
meshtastic --set bluetooth.fixed_pin 111111
```
