Introduction
The RTL87x3BFR series chips can be applied to Realtek dual-mode Bluetooth data transfer solution, the Bluetooth chip has a built-in complete Bluetooth protocol stack, supports SPP and GATT profile. The Bluetooth chip is connected to the external master through the UART and provides rich and flexible command. Allowing the device to easily support Bluetooth functions.
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.
