Did you add capacitors?? When things are flakey:work, quit, work ... that may be what's happening..
Yes terryking228, I added capacitors as you suggested and it worked perfectly.
IF you add a 10uf to 100uf capacitor in parallel with a .1uf capacitor across the radio module's GND and 3.3V pins it will probably work.
So I need 2 capacitors for the nrf to work on 3.3V? I mentioned in another topic that with my 1uf capacitor i can only use the nrf on the 5V pin and not the 3.3V pin.
