BLE

4K bytes/s(android.IOS)

BLE and IOS or Android connection communication speed 4K per second (supports 38400 baud rate continuous data transmission, higher than 38400 baud rate can not be sent continuously, the middle extension time)

Pin function and application 

JDY-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
