Model: JDY-33 Working frequency band: 2.4GHZ Communication interface: UART Working voltage: 3.6-6V (recommended 5V) Working temperature: -40℃ - 80℃ Antenna: Built-in PCB antenna Transmission distance: 30 meters Master-Slave Support: Slave Bluetooth version: Bluetooth 3.0 SPP +BLE4.2 SMT soldering temperature: Working current: 6.5mA Deep sleep current: Transmit power: 6db (maximum) Receive sensitivity: -96dbm SPP maximum throughput: 16K bytes/s (android, windows) When connected with android and computer Bluetooth, the communication speed can reach 16k bytes per second, and no packet loss (support serial port to send and receive data continuously) BLE: 4K bytes/s (android, IOS) When BLE is connected to I0S or Android, the communication speed is 4K per second (supports 38400 baud rate to send and receive data continuously, higher than 38400 baud rate cannot be sent continuously, and a delay needs to be added in the middle) Pin Description: PWRC: Sleep wakeup pin VCC: Power pin (5V power supply is recommended for power supply) GND: power ground TXD: Serial output pin TXD: Serial input pin STAT: connection status pin (The default is not connected to low level, after connection is high level, the state can be set by AT+STTS command) The general application of JDY-33 only needs to connect 4 pins of VCC, GND, RXD, TXD. The connection state needs to be disconnected, and AT+DISC\r\n is sent. In the unconnected state, it needs to be deep sleep to send AT+SLEEP\r \n, After deep sleep, you can wake up through the falling edge of the EN pin, or through serial data. Generally, it is recommended to use the serial port to send the AT+VERSION\r\n command to wake up
