RS232 → Bluetooth 3.0 wireless bridge (plug-and-play, no firmware change required)

Short Introduction

A high-performance long-range Bluetooth 3.0 RS232 adapter for stable wireless serial communication up to 100 meters, ideal for industrial equipment, instruments, and smart devices.

Product Description

This Bluetooth 3.0 RS232 adapter provides a reliable cable replacement solution for wired serial connections. It can be directly connected to microcontrollers and processors, enabling transparent wireless data transmission between devices with simple plug-and-play operation.
The adapter supports master-slave working mode. After correct wiring and power-on, the master and slave units automatically connect, identify, and memorize each other. Once paired, it operates just like a standard serial cable for seamless device communication.
In addition to master-slave pairing, the module can work independently. When connected to user equipment, it can be detected by other Bluetooth devices such as PDAs, PCs, and mobile terminals to establish secure communication and provide stable serial data services.
Equipped with LED indicators for power, working status, and connection status, this adapter ensures clear operation monitoring. It supports encrypted transmission to guarantee data integrity and confidentiality. Widely used in digital weighing, surveying and mapping, industrial control, medical instruments, and various electronic information products.
