RN 42 Bluetooth
This module provides a very simple way to replace a serial cable connection with a Bluetooth Serial Port Profile (SPP) connection.
As well has having a good set of features accessible via an AT-style command set, one great feature is that out of the box, it is configured to be a serial port host listening for an incoming serial port request. This means that immediately, without any configuration, you can pair the RN42 with a Bluetooth enabled computer, and have a 115200-8-N-1 serial connection
