JDY‑25M BLE5.0 Bluetooth Module 80m Long Transmission Distance 1.9‑3.6V Serial Port Wireless Communication Board For Arduino IoT Project

JDY‑25M BLE5.0 Bluetooth Module

📌 Product Overview

JDY‑25M is a high‑performance BLE5.0 Bluetooth module supporting master‑slave transparent transmission, iBeacon, BLE probe and powerful MESH networking function. It supports up to 65280 network‑connected devices, adopting multi‑hop wireless anti‑collision technology. The module can be set as routing node or end node freely. Routing nodes realize data relay while end nodes maintain ultra‑low‑power sleep mode with wake‑up trigger. Users only need to configure NETID and short address for automatic networking. Serial data transmission is transparent for mobile APP development, compatible with legacy APP programs. It works at 1.9‑3.6V wide voltage, built‑in PCB antenna with 80m communication distance, widely used in smart home, remote control, LED lighting and sensor acquisition projects.

✨ Core Features

1. Direct data communication with iOS and Android mobile APP, working current approx 1mA.
2. High‑speed data transmission between master and slave modules.
3. Built‑in iBeacon ultra‑low‑power broadcast function.
4. Support iBeacon probe and BLE Bluetooth scanning function.
5. Multi‑slave connection mode, multiple slaves connect to multiple mobile phones for simultaneous data transmission.
6. Bluetooth MESH networking for serial transparent transmission, IO output control and button input control.
7. MESH transmission supports acknowledged and unacknowledged two‑way communication.
8. Support network remote control function.
9. Mixed master‑multi‑slave working mode, master connects slaves while slaves connect mobile phones synchronously.
10. Ultra‑low‑power sleep, deep sleep current as low as 3uA.
11. UART serial port communication, configurable parameters via AT commands.
