Introduction

BLE-SER Bluetooth-to-Serial module is developed based on the CH9140 chip, supporting Bluetooth BLE4.2 with a maximum serial baud rate of 1Mbps. The module supports master-slave integrated mode or slave-only mode, with automatic connection or bonding available in master-slave mode. A PC-side virtual COM port driver is provided, enabling the Bluetooth interface to work directly with serial debugging tools and compatible serial applications — no secondary development required for serial interface communication, making it easy to achieve cable-free serial connectivity without distance limitations.
