BM78
General Description
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 con-
nectivity 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.
