Returns the signal strength reported by the paired device from ``0`` (no signal) to ``4`` (full strength).
### ~hint
## ~hint
The functions in the ``devices`` namespace allow the @boardname@ to communicate with a separate (remote) device,
such as a smartphone, over Bluetooth (Smart).
The set of supported events will depend on the remote device and the @boardname@ apps available for the remote device.
**App required** You must use one of the [micro:bit apps](https://microbit.org/guide/mobile/) to use this functionality.
