I. Introduction to functions
Jdy-41 adopts 2.4g technology development, visual distance 160 meters, serial port transparent transmission, switching quantity control, low power consumption remote control, learning remote control, especially jDY-41 and JDY-40 only PCB package compatibility, communication protocol is completely different, JDY-41 remote transparent transmission communication, each packet of data has verification, The receiver will not receive the code data, have improved a lot in terms of communication distance, communication distance measured 160 meters passthrough not packet loss, support the receiver of a serial port to send command control GPIO pin high and low level, support passthrough serial communication, serial communication, serial communication and sending passthrough serial port communication said no format, serial communication to send and receive transmitter to send what, The receiver the sender will receive all serial input data, support serial communication instruction target address specified device before data communication, passthrough communications support ACK response communication, the sender to the receiver passthrough data, transmitting terminal will be able to know if the receiver have received, a learning remote control study support the receiver transmitter ID code, after the success of the learning, The remote control receiver will only accept the specified remote control
Ii. Application Scenarios
2.1:2.4g remote control
2.2:2.4g wireless serial port transparent transmission
2.3: Bluetooth to 2.4g or WIFI to 2.4G serial communication
2.4: I/O switch quantity control
2.5:2.4g toy control
2.6: Smart home control applications
Tip: IO control, switching, remote control and other applications without external MCU
