DESCRIPTION
The RN42SM is a though hole, low power and highly flexible Bluetooth socket module. It supports SPP/DUN and HCI Bluetooth interface protocols, is simple to design in, and fully-certified. With its high performance on chip antenna and support for Bluetooth Enhanced Data Rate (EDR), the RN42SM delivers up to 3 Mbps data rate for distances to 30 meters. The RN42SM socket module is the perfect method for adding Bluetooth wireless capability to existing products without redesign, saving significant time and money.

Starting with firmware 6.10, Roving Networks RN41, RN42, RN41XV and RN42XV modules support both SPP and HID in the same module. By default, the bluetooth module powers up in SPP profile mode. It can be switched to HID by issuing S~,6 command in CMD mode or by pulling high GPIO11 (Pin 9 on XV modules) during power up.
