BLE/UART/USB Transceiver Module BLE2U
Manual
Version: 1C
1. Overview
The BLE/UART/USB transceiver module (BLE2U) is developed based on CH9143 to implement data
transmission between BLE, USB interface and UART. The BLE supports master mode, slave mode and
master-slave mode. BLE communication and parameters can be configured in slave mode and master-slave
mode, and BLE4.2 is supported. The UART supports AT command configuration and MODEM signals. The
baud rate can be up to 1Mbps. It can implement online debug or data monitor between computer USB
interface, serial port and Bluetooth at the same time.
USB and BLE virtual serial port technology. A virtual serial port driver is provided on the computer,
shielding the underlying technical details of BLE and USB, with no secondary development required. It is
compatible with common serial port applications and serial debug tools, easy to implement transmission
between 3 "serial ports".
