Description: JDY-40 is developed with 2.4G technology, the sight distance is 120 meters, using serial port communication interface, using simple and fast, only need to understand the serial knowledge of the JDY-40 can be applied to the product. Pin function description: Pin The name of the discipline Function 1 GPI01 Input-output IO, which can be configured by AT+CLSS 2 GPI02 Input-output IO, which can be configured by AT+CLSS 3 GPI03 Input-output IO, which can be configured by AT+CLSS 4 GPI04 Input-output IO, which can be configured by AT+CLSS 5 GPI05 Input-output IO, which can be configured by AT+CLSS 6 GPI06 Input-output IO, which can be configured by AT+CLSS 7 GPI07 Input-output IO, which can be configured by AT+CLSS 8 GPI08 Input-output IO, which can be configured by AT+CLSS 9 VCC Power supply (2.2-3.6) 10 RXD Serial port input pin 11 TXD Serial port output pin 12 SET AT command switching pin (low level AT instruction, high level transparent transmission) 13 CS Transmission or push button mode: CS pin (low level wake-up, high level sleep). IO receive mode:the CS pin needs to be suspended or pulled up 14 GND Power supply Application scene: 1:2.4G panel switch 2:2.4G remote control 3:2.4G transmission 4: one to many control of mobile phone 5:IO switching control 6:2.4G toys 7: smart home control application Technical parameter: Model JDY-40 Working band 2.4G Emissive power Maximum 12dB working temperature -40 C - 80 C Reception sensitivity -97db transmission distance 120 meters working voltage 2.2V-3.6V TX current 40mA RX current 24mA Sleep current 5uA communication interface Standard TTL serial port Default configuration: sequence function parameter instructions 1 baud rate 9600 AT+BAUD 2 wireless ID 8899 AT+RFID8899 3 device ID 1122 AT+DVID1122 4 channel 001 AT+RFC001 5 emissive power 12db AT+POWE9 6 equipment type A0 AT+CLSSA0 Communication: it is necessary to configure the RFC, DVID, and RFID that need the communication module to be the same. The module and the module can communicate. When the module comes out, the parameters are all unified, and the user can configure it according to its own needs. AT instruction instructions: Specifically, the JDY-40 module needs to add the ending symbol rn to send the AT instruction.

C 1: remote control or IO button without indicator (transmitter). C 2:IO normally high level, after receiving the signal, low level, delay. High level after 30mS C 3:IO is usually low level, after receiving the signal, the high level has been Recovery of low level after delayed 30mS C 4:IO is usually low level, and receives the high level of the pressed signal. Receive raised signal low level The IO level is reversed when the C 5:IO receives the pressed signal.
