10.6.1. Packet with Fixed Content
The payload has its pre-defined content, namely “BUTTONx” where x can be 1, 2, 3, or 4. The used packet can be
seen below:
10.6.2. Key Fob Packet (Type A)
The following development kits use also this type of packet:
Si4010 Key Fob Demo Kit with AES Capability 434 MHz
Si4010 Key Fob Demo Kit with AES Capability 868 MHz
Si4010 Simplified Key Fob Demo Kit 434 MHz
Si4010 Simplified Key Fob Demo Kit 868 MHz
The used packet is shown in Table 12.
OUT3/F1 sent out first, OUT0–OUT3 represent the four LED outputs, F0–F1 represents the function bits. Output
functions are controlled by the function bits. Function bits’ operations are shown on the following table:
