Arduino and RF24 library: communication stops after short amount of time I am using two Arduino Unos, NRF24L01+ transceivers, and a few components as per this site on which I am following the second tutorial on this page: Arduino Wireless Communication – NRF24L01 Tutorial.

I am using the exact code from the page as well - and have set everything up as per the diagrams, however everything stops working after a short amount of time. Usually between 15 and 30 seconds, everything stays powered but it seems like the transceivers stop communicating. A reset of the Transmitting board (the one with the potentiometer) will fix the problem until it again stops 15 or 30 seconds later.

Any idea what might be going on?
Your question does not provide much information to go on.  Setting up as given in the tutorial is a good start, but does not guarantee that there will be no problems.  It can still either be a problem due to hardware or firmware.  

Firmware problems:


The radio data may be getting corrupted after some time, which shows up as a failed radio transaction
You inadvertently change the register settings of the radio


Hardware problems:


There is noise interference on the radio channel you are using due to the urban environment (wifi, etc).  Does the system work any better on a different channel?
The radio drains too much power and browns out, then will revert to default settings on the IC rather than the ones set by your Arduino sketch.
