DM182017-1 is a wireless security remote control development platform for wireless security remote control applications with transmit frequency of 433.92MHz. The pre programmed demo is used to demonstrate the basic operation of Remote Keyless Entry (RKE) solutions. The demo highlights capabilities of transmitting and receiving data that is secured over the air. The kit demos two security protocols, KEELOQ Classic and KEELOQ AES. Pressing any one of four buttons on the red key fob, the information about the pressed button will be encrypted and transmitted. When data is being transmitted, the LED on the key fob will flash. When button 1 or 2 is pressed, the information is secured with KEELOQ Classic before the transmission; when button 3 or 4 is pressed, the information is secured with KEELOQ AES before the transmission. When the SX1239 Receiver PICtail Daughter Board receives a secured packet, the content of the packet is acquired by the target application microcontroller.
