How can I store the received data from nRF24l01+ module in an array (code in description)?
I would suggest to send 2 bytes to this module
the first byte is the pipe number (0xE1,0xE2,0xE3,0xE4)
and in the second byte Data

void loop()
{
  if (radio.available())
 {
  radio.read(&amp;text, sizeof(text));
  for (int i=0; i &lt; 4 ; i ++)
   {
     if( text[0] == ((unsigned char *)(&amp;pipes[i]))[0] 
        recArray[i] = text[1];
   }
  Serial.println(text[1]);
 }
}
