CH9140 Datasheet 1 http://wch.cn BLE to UART Bridge Controller CH9140 Datasheet Version: 1B http://wch.cn 1. Overview 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. The figures below are some application block diagrams of CH9140: Computer, mobile phone, etc. BLE host (virtual serial port driver) Serial port application or APP -BLE- CH9140 chip in BLE UART MCU or other serial port host-slave devices mode or slave mode Figure 1 Block Diagram of Serial Communication between BLE Host and Serial Port Device through CH9140 BLE MCU or other serial port devices CH9140 chip in BLE UART host-slave mode or slave mode -BLE- CH9140 chip in BLE host-slave mode UART MCU or other serial port devices Figure 2 Block diagram of communication between MCUs or Serial Port Devices on Both Ends through CH9140 in BLE Host-slave mode 2. Features l l l l l l l l l l Provide computer-end BLE virtual serial port driver. Compatible with existing serial port software and tools, without secondary development. Support BLE host connection for Windows/Linux/Android/iOS and other systems. Support BLE host-slave mode and slave mode. Support automatic connection or binding in BLE host-slave mode. Support hardware configuration parameters. Transmission distance: 100 meters. Support adjustable 8 positions of transmission power. The power-off sleep current is 0.3uA. Support 3.3V and 2.5V working voltage. PDF
