Introduction

Low-power Bluetooth (BLE) RF module for short-range wireless communication applications. Features low power consumption, compact form factor, extended transmission range, and strong anti-interference capability. The module is equipped with a high-performance meandering antenna and adopts a stamp-hole (castellated) hardware interface design. This module supports the development of Bluetooth 4.2 (BLE) based consumer electronics and mobile peripheral products, delivering improved operational reliability, enhanced signal transmission range and interference immunity, interoperability between different electronic devices, and significantly extended battery life. Provides a rapid BLE solution for communication between customer products and smart mobile devices.

The module operates in either Bridge Mode (transparent transmission mode) or Direct Drive Mode. In Bridge Mode, the host CPU can perform bidirectional communication with mobile devices via the module's general-purpose UART interface, and manage specific communication parameters through AT commands. In Direct Drive Mode, users add minimal peripheral components to the module, and an app drives the module directly via the BLE protocol, enabling monitoring and control of the module from smart mobile devices.
