Welcome in the forum.
Sorry to say, but there is no special magic to bring your PRoC to life. It must be a hardware problem.
Since you were able to program the chip, you should be able to debug it using the Miniprog3 or the Kitprog. this should usually help.
Thank you for the quick reply !
You're right. In fact, I got an hardware issue with the 24 MHz crystal which was badly connected.
Now it seems to work really better .. but still no radio link. So, I continue to investigate on antenna side.
