Arduino RF24 library Delay after write function causes no byte availability
In my situation the issue was with the Transmitter not continuing to transmit after a delay. I was able to resolve the issue using the powerDown (http://maniacbug.github.io/RF24/classRF24.html#aa0a51923a09ba4f3478aba9be0f8a6a1) and powerUp (http://maniacbug.github.io/RF24/classRF24.html#a5cdaf47aa0edd6dca1b9a8bb7972a1a3) functions. Here is a snipet of my code. "radioTx" is the name assigned to my transmitter.

//standard code setup for arduino uno board examples
radioTx.begin();
radioTx.setChannel(108);
radioTx.openWritingPipe(pipe);

}

void loop() {

  int dist_cm = sonar.ping_cm();


  Serial.println(dist_cm);
  radioTx.write(&amp;dist_cm,sizeof(dist_cm));
  radioTx.powerDown();
  delay(5000);
  radioTx.powerUp();

  }
