If the power amplifier is required to increase output power, set PA to 1 using command PA 1 <return>.
Transmitting an FSK message Without Header
Below is an example of sending an FSK modulated message consisting of a Preamble, an ID byte, eight
bits of data, and an EOM. The data rate is 1000 bits per second.
To send an FSK data frame with ID 0xA5 (10100101 binary), one data byte of 0xff (11111111 binary):
Freescale Semiconductor
1. Set required baud rate with data rate DATARATE 2400 <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 P0010101011110000E <return>.
5. To repeat SEND command, press return repeatedly.
