Next thing to do is to set the registers for continuous transmit of random characters. See if you get an output from the transmitter. At this point, don't worry about what comes out, just that something does. Next, I have smoked a number of cc1100s with only a slight overvoltage pulse. Is it possible to jumper the mfg board processor output to the CC1100 input? This will test the CC1100 in circuit and see if it is operating.I did this with the development kit and saved mucho time.
that's all for now,
