GPIO definitions
// set GPIO0 to RX DATA
SpiRfWriteAddressData((REG_WRITE | GPIO0Configuration), 0x14);
// set GPIO1 to TX State & GPIO2 to RX State
SpiRfWriteAddressData((REG_WRITE | GPIO1Configuration), 0x12);
SpiRfWriteAddressData((REG_WRITE | GPIO2Configuration), 0x15);
Next, define your RF parameters based on application specific data rate,
deviation, receive baseband bandwidth etc.,
// set modem and RF parameters according to the selected DATA rate
RFSetRfParameters(data_rate);
return RF_OK;
