Hello,
I have developed a board integrating the CC2538 with an integrated SMD antenna.
The problem that I have is that in order to communicate properly between devices I have to initialize some registers like FSCAL0/1/2/3 with specific values different from the default values. If I use these values with another board it didn't communicate properly so I have to change the values again.
It seems like I have to perform a calibration in every single board to get a proper RF communication. Is that normal ? Is their a kind of procedure to follow in order to solve this behavior ? Am I doing something wrong ?
Thanks in advance
