1. INTRODUCTION
FSC-BT816S is a fully integrated Bluetooth module that complies with Bluetooth 4.2 dual
mode protocols(BR/EDR/LE). It provides several interfaces such as UART, I
2
C, PCM, AIO,
PIO, etc,which can customized different applications.
FSC-BT816S supports various profiles. It integrates MCU, Baseband controller, RF, etc. in a
small package, so the designers can have better flexibilities for the product shapes.
FSC-BT816S can be controlled by UART port or other interfaces. Please refer to Feasycom
software design guide for the interfacing protocol.
