Introduction

The CH9141 is a chip realizing bidirectional transparent transmission between Bluetooth low energy (BLE) and UART, supporting broadcast mode, host mode and slave mode, BLE4.2. It supports serial AT configuration and BLE communication configuration in slave mode and MODEM contact signal. The chip provides universal GPIO, synchronous GPIO and ADC acquisition functions, with the baud rate of UART up to 1Mbps. In the BLE slave mode, parameters such as BLE name and manufacturer information can be set, which can be easily configured through APP or serial port commands, which is convenient and fast. The virtual serial port driver on the computer is provided to directly use serial port debugging tool for the BLE interface. It is compatible with the serial port application program, so it can communicate with the serial port without secondary development, easily realizing the exemption of wire plugging and not being limited by the cable distance.
