Register code to run when the signal strength of the paired device changes.

|

|
||||
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.
|
||||
For another device like a smartphone to use any of the Bluetooth "services" which the @boardname@ has, it must first be [paired with the @boardname@](/reference/bluetooth/bluetooth-pairing). Once paired, the other device may connect to the @boardname@ and exchange data relating to many of the @boardname@'s features.
