RTL87x3BFR Series

Introduction

The RTL87x3BFR series chips can be applied to Realtek dual-mode Bluetooth data transfer solution, the Bluetooth chip integrates a complete Bluetooth protocol stack and rich application instructions. The main MCU is connected to the Bluetooth chip through UART, and uses application instructions to configure the basic connection parameters of the Bluetooth chip to expand the Bluetooth transparent transmission interface.
