I have used the NRF24L01 many times but I never noticed this issue because I have been
automatically adding electrolytic caps to my power lines since I started in electronics 40
years ago so I would never have tried to use it before going through this routine ritual
when setting up the breadboard. I typically use 10uF for the Reset pin and 47uF or
greater for power rails. (100uF is a good round number that is usually enough). You
can never have too much capacitance on your power rails.

So you suggest the best choice is to use 100uF between VCC and GND ?
