1. Overview
The BLE to UART module (BLE-SER) is developed based on CH9140, which supports BLE4.2. The baud
rate is up to 1Mbps. The module supports
Bluetooth
®
Low Energy (BLE) master-slave mode and slave mode,
and it supports automatic connection and binding in master-slave mode.
Providing PC-side virtual serial driver can directly call Bluetooth interface through the serial port, which is
compatible with serial debug applications, so it can communicate with UART with no secondary
development required, easily implementing the exemption of wire plugging and not being limited by cable
distance.
