Specifications

The Microchip BM78 is a Bluetooth Version 4.2 Dual-Mode Module that supports BR/EDR and BLE communication. The module provides a fully certified Bluetooth solution that removes the hurdle of RF design regulatory and compliance testing, reducing development time.

The BM78 supports GAP, SDP, SPP, and GATT profiles. Data is transferred over the Bluetooth link via transparent UART mode, which when combined with the module’s UART interface simplifies the task of integrating the BM78 with a host MCU. Configuration of the module can be completed by using a Windows compatible Graphical User Interface (GUI) or directly by MCU.
Supports Bluetooth Classic (BR/EDR) and Bluetooth Low Energy (LE)
