CC1101 running a PIC controller or building a peer-to-peer network for a radio engineer (part 2)

They say that the promised 3 years are waiting ...

I did this publication , with the promise to lay out libraries suitable for use by radio engineers who are not programming gurus.

For many reasons, I had to postpone that project. Last year I returned to him.

In this case, additional solutions were used, which may also be interesting.

But! During this time, new chips, new solutions, etc. appeared.

Is the chip CC1101 relevant now? Is the theme of simple peer-to-peer networks without frills relevant?

If this is relevant, then I will develop the topic.
