Device Overview

Summary

The BM78 is a fully-certified Bluetooth® dual-mode (BR/EDR/LE) module for designers who want to easily add dual mode Bluetooth wireless capability to their products.  Delivering local connectivity for the Internet of Things (IoT), the BM78 bridges your 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 mode over UART, making it easy to integrate with any processor or Microcontroller with a UART interface.  Configuration is made easy using a Windows® based GUI or directly via UART by a microcontroller.

The Microchip Bluetooth Data (MBD) mobile app is available to speed up development for both Android and iOS.

Microchip's complimentary and confidential Wireless Check online design review service is available for customers who have selected our products for their application design-in*.
*The online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
