RF Message Formats

Transmitting Messages With Header Field

Sending a message with a header field can easily be done. Simply place the sequence '0110' in the

message at the required position.

For example, to send a message with an ID of 0x55 (01010101 binary), data byte 0xff (11111111 binary),

and a header field (0110 binary), at data rate of 1000 bps with OOK modulation:

1. Set required baud rate with DATARATE 1000 <return>.

2. To select OOK modulation, set the MODE pin to 0 using command MODE 0 <return>.

3. To enable the Tango3 IC, set the Enable pin to 1 with command ENABLE 1 <return>.

4. Use command SEND P01010101011011111111E <return>.

5. To repeat the SEND command, press return repeatedly.
