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.
Function Introduction:
- 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)
- 8: IO mode (applies to mobile phone control relay or LED light off)
- 9: indoor room application (application to collect iBeacon data to Realization range positioning)
Technical Parameters:
- 1: communication rate 3K Bytes / second
- 2: APP transparent transmission when the serial port supports 1024Bytes write
- 3: effective communication distance 15 to 30 meters
- 4: support PWRC pin control sleep
- 5: support IO port control Open connection
Two Pin Function Description:
DISC pin: used to actively disconnect the Bluetooth connection (default high level, low level disconnect)
PWRC pin: used to wake sleep (default It is in sleep state. When this pin is grounded, it can send AT command
- VCC pin: it is the power supply pin of the module, the power supply voltage range is 3.6V to 6V.
- GND pin: power ground
- TXD pin: serial output pin
- RXD pin: serial input pin
- three wiring method
This figure shows the wiring method during transparent transmission. Currently, the DIS pin is not connected. If the user is connected to the JDY-08 module by using the MCU, the DIS pin can be connected to the IO port of the MCU.
Four: AT command
JDY-08 is a multi-function module, AT command, please read the JDY-08 module standard manual carefully.
