JDY-08 BLE 4.0 Module

Product Description

JDY-08 transparent transmission module is based on Bluetooth 4.0 protocol standard, the working frequency band is 2.4GHZ range, the modulation mode is GFSK , the maximum transmission power is 0db , the maximum transmission distance is 80 meters, and the TICC2541 chip design is adopted, which allows users to modify the device name through AT command, service UUID, transmission power, pairing password and other instructions, convenient and fast to use flexible.

Bluetooth Main Chip Model: CC2541

Product Function

1. WeChat transparent transmission (support AirSync protocol, applied to WeChat H5 or manufacturer server communication, including long packet data parsing and receiving).

2. APP transparent transmission (support Android, IOS data transparent transmission).

3. iBeacon mode (support WeChat shake One-shake protocol and Apple iBeacon protocol).

4. Sensor mode (temperature, humidity, and many other sensor data acquisition applications).

5. Host transparent transmission mode (data transmission between application modules, host and slave communication).

6. Host observer mode ( Application sensor, indoor positioning).

7. PWM mode (applicable to motor speed regulation, LED light level adjustment).
