RN4678-V/RM100 More Semiconductors - ICs by Microchip Technology
Bluetooth Dual Mode Module
The RN4678 is a fully certified Bluetooth Dual Mode (BR/EDR/LE) 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.
The Microchip Bluetooth Data (MBD) mobile app is available to speed up development for both Android and iOS.
