Those seem like reasonable suggestions.
1) I was researching the E2E about frequency drift and PLL lock when I saw you answering a different question.
You said:
To ensure that you are going into compression on the LNA inputs of the CC1101 you should have a distance of at least 2 meters between the transmitter and the receiver.
I am often less then 2 meters could this be part of the problem? If so is there a work around?
2) For checking frequency drift I should read FREQEST?
3) For checking PLL lock I should read FSCAL1?
Thanks
