The BM78 module is a fully-certified， Bluetooth version 4.2 module for customers to easily add dual-mode Bluetooth wireless capability to their products. The BM78 is built around Microchip‘s IS1678 Bluetooth dual-mode module， and it is available in ROM-based （BM78SPPx5NC2） and Flash-based （BM78SPPx- 5MC2） versions. Refer to Section 9.0 “Ordering Information” for additional information on the BM78 SKUs. The BM78 bridges the customer products to smart phones or tablets for convenient data transfer， control， and access to cloud applications delivering local connectivity for IoT. The BM78 supports GAP， SDP， SPP， and GATT profiles. Data transfer is achieved through the Bluetooth link by sending or receiving data through transparent UART mode， making it easy to integrate with any microprocessor or Microcontroller （MCU） with a UART interface. It also enables a easy configuration by using a UI tool， a Windows configuration utility， or directly through UART by MCUs.
