Descritpion:
JDY-33 is a classic Bluetooth + BLE dual-mode Bluetooth module, can communicate with Bluetooth-enabled computers (desktop, notebook), mobile, IOS. It can be applied to Bluetooth POS machine, Thermal printer, Smart home control, Automotive ODB testing equipment, Bluetooth various transparent product applications, Sharing charging treasure, sharing weight scale etc.
DY-33 general application only needs to connect 4 pins of VCC, GND, RXD, TXD, such as in the connection state. Disconnect, send AT+DISC\r\n, and send deep sleep to AT+SLEEP\r\n when not connected. After deep sleep, you can wake up by the falling edge of the EN pin, or you can wake up the data through the serial port. Use the serial port to send AT+VERSION\r\n command to wake up. When connected with android and computer Bluetooth, the communication speed can reach 16k byte per second, and no packet loss (supports serial port to continuously send and receive data).
