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.
DESCRIPTION
CHIP
Highlights
GATT and SPP profiles inside; Communicate with external MCU by UART.
Baud rate up to 4Mbps; Default baud rate 115.2kbps; UART I/F (H4 supported); Hardware flow control supported.
Full-featured dashboard SDK, with supporting mobile phone APP engineering, which greatly reduces customer's development workload and accelerates the implementation of project.
