The `bluetooth` manifest property declares which permissions are available for the [bluetooth](https://developer.chrome.com/docs/apps/reference/bluetooth.md.txt)
API.

## Sample manifest.json

```json
{
  "name": "My Bluetooth app",
  "bluetooth": {
    // Permission for chrome.bluetoothSocket:
    // The application is allowed to communicate with devices
    // using the protocols, profiles, or services identified by
    // the UUIDs 0x1105 and 0x1106 using the BluetoothSocket API.
    "uuids": [ "1105", "1106" ],
    "socket": true
  },
  ...
}
```

```json
{
  "name": "My Bluetooth app",
  "bluetooth": {
    // Permission for chrome.bluetoothLowEnergy:
    // The application is allowed to communicate with devices
    // using the profiles identified by the UUIDs 0x180D, 0x1809 and 0x180F
    // using the BluetoothLowEnergy API.
    "uuids": [ "180D", "1809", "180F" ],
    "low_energy": true
  },
