## Advanced usage
### Override default bindings
By default, noble will select bindings to communicate with Bluetooth devices depending on your platform. If you prefer to specify what bindings noble should use:
```javascript
var noble = require('noble/with-bindings')(require('./my-custom-bindings'));
