RN4678

The RN4678 is a fully certified Bluetooth version 4.2 (BR/EDR/LE) Dual Mode module, which enables the designer to easily add classic Bluetooth and Bluetooth Smart capability to their products. Delivering local connectivity for the Internet of Things (IoT), the RN4678 bridges the product to Smart Phones and Tablets for convenient data transfer, control and access to cloud applications.

This Bluetooth SIG certified module provides a complete wireless solution with Bluetooth stack on-board, integrated antenna, and worldwide radio certifications in a compact surface mount package, 22 x 12 x 2.4 mm. It supports GAP, SDP, SPP, and GATT profiles. Data is transferred over the Bluetooth link by sending/receiving data via transparent UART mode, making it easy to integrate with any processor or microcontroller with a UART interface. Configuration is made easy through ASCII commands via UART.

Available iOS Applications for the RN4678:


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