1. Introduction
Part Name: RF-BHS < ISSC BM77SPP03MC2 Bluetooth module>
Part Number: BM77SPP03MC2-xxxxxx
The ISSC BM77SPP03MC2 Bluetooth module is design for Bluetooth standard SPP/ BLE electronic accessories
via Bluetooth connectivity. It is available in the 2.4GHz ISM band Class 2 Radio, compatible with Bluetooth Core
Specification Version 3.0/ 4.0 + EDR.
ISSC IS1677NM single chip solution combines transceiver and baseband function to decrease the
external components. It narrows down the module size and minimizes its cost.
The optimized power design minimize power consumption to keep low battery
