Modul Bluetooth BT SPPC SPP-C JDY08 JDY 08 Arduino Serial Module HC05

Introduction to features: 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) JDY-08 transparent transmission module is based on the Bluetooth 4.0 protocol standard, the working frequency of 2.4GHZ range, modulation scheme is GFSK, the maximum transmit power of 0db, maximum transmission distance of 80 meters, the use TICC2541 chip design, allowing users to modify the device name through AT commands service UUID, transmit power, pairing password instructions, convenient to use and flexible. Description: 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 The new V508 firmware upgrade to support seria
