Description:

JDY-08 Transparent module is based on the Bluetooth 4.0 protocol standard, the working frequency band is 2.4GHZ, the modulation mode is GFSK, the maximum transmission power is 0db, the maximum transmission distance is 80 meters, adopt the TICC2541 chip design, support the user through the AT command to modify the device name , Service UUID, transmit power, matching password and other instructions, convenient and quick to use flexible. Feature: 1: WeChat transmission (support AirSync protocol, used in WeChat H5 or factory server communications, including long packet data analysis transceiver) 2: APP transparent (support Android, IOS data transmission) 3: iBeacon mode (support WeChat shake agreement with Apple iBeacon protocol) 4: sensor mode (temperature, humidity and many other sensor data acquisition applications) 5: host transparent mode (between the application of data transmission between the module, the host and the slave communication) 6: host observer mode (application sensor, indoor positioning) 7: PWM mode (used in motor speed, LED light brightness adjustment) 8: IO mode (applied to mobile phone control relay or LED off) 9: indoor room application (application of iBeacon data to achieve the scope of positioning) Parameter: 1: Communication rate 3K Bytes / sec 2: APP through the serial port support 1024Bytes write 3: effective communication distance of 15 to 30 meters 4: Supports PWRC pin control sleep 5: support IO port control disconnect Two pin function description DISC pin: used to actively disconnect the Bluetooth connection (the default high, low disconnected) PWRC pin: used to wake up sleep (the default is in sleep state), the use of this pin ground can be issued AT command VCC pin: for the module's power supply pin, the supply voltage range between 3.6V and 6V GND pin: power ground TXD pin: serial output pin RXD pin: Serial input pin This figure shows the wiring when the transmission, the current DIS pin is not connected, if the user is using the MCU and JDY-08 module connection, the DIS pin can be connected to the MCU IO port. AT command JDY-08 for the multi-function module, AT command specific Please carefully read JDY-08 module standard manual Package Included: 1 x JDY-08 Bluetooth 4.0BLE Low Power CC2541 Support Airsync iBeacon Module
