Introduction

CH9140 is a Bluetooth low energy (BLE) to UART bridge controller, which supports BLE host- slave mode or slave mode and supports BLE4.2. The baud rate is up to 1Mbps. It supports MODEM contact signal, and supports automatic connection or binding in BLE host- slave mode. The virtual serial port driver on the computer end is provided for BLE interface to directly use serial port debugging tool. It is compatible with the serial port application program, and it can communicate with UART without secondary development, easily realizing the exemption of wire plugging and not being limited by the cable distance.
