Getting Started problem - NRF24L01 - Arduino Nano and Uno

Hi,
I have two NRF24L01 modules with soldered 63V47uF capacitors. They worked fine someday with exact same configuration - Uno and Nano.

So, I connected them like this

This is Nano, but I connected NRF to Uno same as to Nano.

I'm using GettingStarted example from the newest RF24 library. I'm using also newest Arduino IDE version.

I was strugling with them for a few days.
Yesterday I thought that NRF modules may be not working properly.
So I found somewhere way to test them.

/**
* First test
*
*/

#include <SPI.h>
#include <RF24.h>
#include "printf.h"

//
// Hardware configuration
//

// Configure nRF24L01 radio module on SPI bus plus pins 8 for CE & 9 for CS
// arguments are (ce, cs)

RF24 radio(9,10);

//
// Set transmit and receive addresses
//

const uint64_t pipes[2] = { 0xF0F0F0F0E1LL, 0xF0F0F0F0D2LL };

void setup(void)
{

  Serial.begin(9600);
  printf_begin();
  printf("\n\rTest connection to modules\n\r");

  //
  // Setup and configure rf radio
  //

  radio.begin();
  
  // Set the TX and RX addreses in the module
  
  radio.openWritingPipe(pipes[0]);
  radio.openReadingPipe(1,pipes[1]);
  

  // radio.setDataRate( RF24_2MBPS ) ;
  // radio.setPALevel( RF24_PA_MAX ) ;
  radio.enableDynamicPayloads() ;
  radio.setAutoAck( true ) ;
  radio.powerUp() ;
  radio.startListening();

  //
  // Print out the configuration of the rf unit for debugging
  //

  radio.printDetails();
}

void loop(void)
{
}

From the first NRF I have this result (Nano)

Test connection to modules

STATUS		 = 0xff RX_DR=1 TX_DS=1 MAX_RT=1 RX_P_NO=7 TX_FULL=1
RX_ADDR_P0-1	 = 0xe7e7e7e7e7 0xffffffffff
RX_ADDR_P2-5	 = 0x00 0xff 0x00 0xc6
TX_ADDR		 = 0xe7e7e7e7e7
RX_PW_P0-6	 = 0xff 0x7f 0x00 0x00 0xff 0x00
EN_AA		 = 0xff
EN_RXADDR	 = 0xff
RF_CH		 = 0xff
RF_SETUP	 = 0x00
CONFIG		 = 0x02
DYNPD/FEATURE	 = 0x7f 0xff
Data Rate	 = 2MBPS
Model		 = nRF24L01
CRC Length	 = 8 bits
PA Power	 = PA_MAX

and from the second one... (Uno)

Test connection to modules

STATUS		 = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0
RX_ADDR_P0-1	 = 0xffffffffff 0xceccceccce
RX_ADDR_P2-5	 = 0x00 0xc4 0x00 0xff
TX_ADDR		 = 0x0000000000
RX_PW_P0-6	 = 0x20 0x20 0x00 0x00 0x00 0x00
EN_AA		 = 0x3f
EN_RXADDR	 = 0x03
RF_CH		 = 0x00
RF_SETUP	 = 0x00
CONFIG		 = 0x00
DYNPD/FEATURE	 = 0x3f 0x3f
Data Rate	 = 1MBPS
Model		 = nRF24L01
CRC Length	 = 16 bits
PA Power	 = PA_MIN

So for start, could you tell me if this results are properly?
I think not so what should I change?

Thanks for answers and sorry for my english.

Have a look at this Simple nRF24L01+ Tutorial. I don't have a Nano but I can't see any reason why it won't work on one.

Wireless problems can be difficult to debug and it will be much easier to help if you start by using one pair of my examples exactly as I have posted them.
