Bluetooth Low Energy PICtail / PICtail Plus Daughter Board

The RN-4870-SNSR is a development board based on the ultra-compact Bluetooth 4.2 Low Energy RN4870 module. The RN4870 uses a simple ASCII command interface over the UART. The board enables evaluation of the RN4870 and development of Bluetooth low Energy applications in two different ways:

1) Out of the box: When plugged into the USB port of a PC, the board will enumerate as a Communication Device Class (CDC) Serial device. Through a terminal program, users can configure and control the module and transfer data using the easy to use provided command set.

2) As a PICtail/PICtail Plus, the board interfaces to Explorer 8 or Explorer 16 Development Board. The Explorer 8/16 modular development system works with one of hundreds of available PIC 8, 16, 32 bit Microcontrollers PIM (Plug-In-Modules). The PICtail bridges the host MCU UART to the RN4870's UART interface for data transfer or configuration using the straight-forward, easy-to-use ASCII style command set.

Available iOS Applications for the RN4870:

Bluetooth Smart Discover

Microchip’s Smart Discover for iPhone or iPad provides the ability to scan and connect to nearby Microchip Bluetooth Low Energy (BLE) peripherals, listen to BLE broadcasters and more.

Bluetooth Sensor App

The Bluetooth Smart Sensor app is used to showcase the capabilities of Microchip's Bluetooth Low Energy (BLE) module with the plug-in sensor board included in the RN4870 development kit.
