NRF24L01 issue, please check my code.

hi,

please can debug code? stuck on simple working code stoped working now. use library: https://github.com/maniacbug/rf24 nrf24l01 recevier , next 1 transmitter:

code: [select]

// http://www.bajdi.com
// sending struct nrf24l01 module
// data sent reading of 2 analog pins
// data received analog reading of 2 pins on other arduino

#include <spi.h>
#include "nrf24l01.h"
#include "rf24.h"

typedef struct{
  float humd;
  float temp;
  float pres_t;
  float pres_p;
  float volt;
}b_t;

b_t server;

rf24 radio(6,5);   // uint8_t _cepin, uint8_t _cspin
const uint64_t pipe  = 0xe8e8f0f0e1ll;

void setup()
{
  serial.begin(9600);
 
  radio.begin();
  radio.openreadingpipe(0,pipe);
  radio.startlistening();
  //radio.printdetails();
}

void loop(void) {
  if( radio.available()) {
    bool done = false;
    while (!done) {
      radio.read( &server, sizeof(server) );
    }
  }

  // serial print received data
  serial.print("server.humd = ");
  serial.println(server.humd);
  serial.print("server.temp = ");
  serial.println(server.temp);
  serial.print("server.volt = ");
  serial.println(server.volt);
  delay(5000);

void loop(void) {
  if( radio.available()) {
    bool done = false;
    while (!done) {
      radio.read( &server, sizeof(server) );
    }
  }
...


this while loop ends when "done" true. when "done" true? can't find in code, loop forever, reading nrf24, if there isn't data read.

try removing while() , "done".

here whole code receiver:
