Using my uP connected via SPI to the CC1120 demo board I can set up and calibrate using demo register values. However, unlike the demo system, I cannot see a carrier in transmit mode or see packets received in receive mode. In receive mode there is carrier detect and RSSI using another demo board to transmit repeated packets, but no decoded packets. I am using the same repeated command sequence as the demo board software, as revealed by a Beagle SPI sniffer.
I would like to see the transmitter working first. How do I set up conditions to generate a CW carrier? This would be a great first step.
I can worry about the receive mode later, since getting the transmitter carrier on the spectrum analyzer is fundamental!
