5.4. Message Format
The modem demo uses the following message format:
Table 5. Packet Structure
Preamble
Synchron Pattern
Packet Length
Payload
(4 bytes)
(2 bytes)
(1 byte)
(up to 40 bytes)
0xAA 0xAA 0xAA 0xAA
0x2D 0xD4
0x01
0x00
1. The Preamble is designed to synchronize the PLL of the transmitter and receiver together.
2. The Synchron byte is a pattern field designed the receiver recognize the beginning of the data.
3. The Packet length defines how many bytes make up the payload.
4. The Payload is the physical data which needs to be sent through the RF link.
If the PB1 (LINK) button is pressed while PC Mode is in the command state, the node sends a message with the
following payload: "Link ??". If the second board receives the message, it sends back an acknowledgement
message with the following payload: "Link OK".
