CH9141 Datasheet 1 http://wch.cn BLE and UART Bidirectional Transparent Transmission chip CH9141 Datasheet Version: 2A http://wch.cn 1. Overview 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. The figures below are some application block diagrams of CH9141: Computer, mobile phone, etc. BLE host (virtual serial port driver) Serial port application or APP UART -BLE- CH9141 chip in BLE slave mode GPIO ADC MCU or other serial port devices Figure 1 Block Diagram of Serial Communication between BLE Host and Serial Port Devices through CH9141 MCU or other serial port devices UART GPIO Synchronous IO ADC CH9141 chip in BLE host mode -BLE- CH9141 chip in BLE slave mode UART GPIO Synchronous IO ADC MCU or other serial port devices Figure 2 Block Diagram of communication between MCUs or Serial Port Devices on Both Ends through CH9141 in BLE Host-slave mode 2. Features l l l l l l Support broadcast mode, master mode and slave mode. Support serial port AT configuration and BLE transmission configuration. Provide computer-end BLE virtual serial port driver. Compatible with existing serial port software and tools, and no secondary development is required. Support BLE host connection for Windows/Linux/Android/iOS and other systems. Provide general GPIO and synchronous GPIO functions, support BLE control. PDF
