JDY-41 2.4G module

Function Introduction:

JDY-41 is developed using 2.4G technology, with a line of sight of 160 meters. It is equipped with serial port transparent transmission, switch quantity control, low-power remote control, and learning type remote control. It is particularly noted that JDY-41 and JDY-40 are only compatible with PCB packaging, and the communication protocol is completely different. JDY-41 has long-distance transparent communication, and each packet of data has a verification function. The receiving end will not receive garbled data, and the communication distance has been greatly improved. The measured communication distance is 160 meters, and transparent transmission does not lose packets. It supports serial port command control of the receiving end GPIO pin high and low levels, and serial port communication supports transparent serial port communication. It also supports communication with the sending command serial port. Serial port transparent communication means that the transmitting and receiving serial port communication has no format, and what the transmitting end sends and the receiving end have no format. All data input from the transmitting end serial port will be received, and instruction serial port communication supports specifying device communication by adding a target address before the data, Transparent communication supports ACK response communication. The transmitting end transmits data to the receiving end, and the transmitting end can know whether the receiving end has received it. The learning remote control supports the receiving end to learn the transmitting end ID code. After successful learning, the receiving end of the remote control will only accept the specified remote control control

Application scenario:

1: 2.4G remote control

2: 2.4G wireless serial port transparent transmission

3: Bluetooth to 2.4G or WIFI to 2.4G serial communication
