RF24 library wont work without scanner program upload.

Hi all,

I’ve been trying to get the RF24 library to work without success until today. I wrote the scanner program to the arduino which showed an output, so then I decided to write the getting started program to the arduino again. This time it works. I removed the capacitor and put it back, and restarted the arduino which continued to fail to send (it says sending … failed). Repeating the process of writing the scanner program first makes the getting started program to work.

I’ve tried this on 2 arduinos, and seems the only way to get the getting started program to work is to first write the scanner program. Any ideas why this would be the case?

Thanks in advance.

It is impossible to know what the problem might be without seeing your code.

I got my nRF24s to work with this Tutorial. I suggest using the TMRh20 RF24 library
