Function introduction
Jdy-41 is developed with 2.4G technology, with a visual distance of 160m, serial port transparent transmission, switch control, low-power remote control, learning remote control. In particular, jdy-41 and jdy-40 are only compatible with PCB packaging, and the communication protocol is completely different. Jdy-41 long-distance transparent communication, each packet of data is checked, and the receiving end will not receive random code data. The communication distance has been greatly improved The signal distance is measured to be 160m, the transparent transmission does not lose packets. It supports the serial port to send instructions to control the high and low level of GPIO pin at the receiving end, serial communication supports transparent serial communication, and communicates with the sending command serial port. The serial port transparent communication means that there is no format for the communication between the receiving and sending serial ports. What is sent by the transmitting end The receiving end will receive all the data input from the serial port of the transmitting end, and the instruction serial port communication supports adding targets in front of the data Address designated device communication, transparent transmission communication supports ack response communication, the transmitting end transmits data to the receiving end, and the transmitting end will know whether the receiving end has received it or not. The learning remote controller supports the receiver to learn the ID code of the transmitter. After the learning is successful, the receiver of the remote control will only accept the specified remote control
Application scenarios
2.4g remote control
2.4g wireless serial port transparent transmission
Bluetooth to 2.4G or WiFi to 2.4G serial communication
IO switch control
2.4g toy control
Smart home control applications
It is suggested that the application of IO control, switch value and remote control does not need external MCU
