NRF24L01+ ne communiquent pas

Bonjour dmlk

Si je suis dans ton cas, j'utilise un programme de monitoring qui me permet de voir si mon module radio est bien "vu" de l'Arduino:

#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
#include "printf.h"

//------------------------------------- Hardware configuration: Set up nRF24L01 radio on SPI bus plus pins 7 & 8 
RF24 radio(9, 10); //Nano IO Shield     https://wiki.iteadstudio.com/Arduino_Nano_IO_shield
//RF24 radio(7,8);  // CE CS
//RF24 radio(9, 10);  // Nano
//RF24 radio(9, 8); //ESP32 Rev1 M5stack

//------------------------------------- Topology
const uint64_t pipes[2] = { 0xABCDABCD71LL, 0x544d52687CLL };              // Radio pipe addresses for the 2 nodes to communicate.

void setup()
{
  Serial.begin(115200);
  printf_begin();

  //----------------------------------- Setup and configure rf radio

  radio.begin();
  radio.setAutoAck(1);                    // Ensure autoACK is enabled
  radio.enableAckPayload();               // Allow optional ack payloads
  radio.setRetries(0,15);                 // Smallest time between retries, max no. of retries
  radio.setPayloadSize(1);                // Here we are sending 1-byte payloads to test the call-response speed
  radio.openWritingPipe(pipes[1]);        // Both radios listen on the same pipes by default, and switch when writing
  radio.openReadingPipe(1,pipes[0]);
  radio.startListening();                 // Start listening
}

void loop(void) 
{
  Serial.println();
  radio.printDetails();                   // Dump the configuration of the rf unit for debugging
  delay(2000);
}

Dans le moniteur à 115200, si le module n'est pas vu:

SPI Speedz	= 10 Mhz
STATUS		= 0x00 RX_DR=0 TX_DS=0 TX_DF=0 RX_PIPE=0 TX_FULL=0
RX_ADDR_P0-1	= 0x0000000000 0x0000000000
RX_ADDR_P2-5	= 0x00 0x00 0x00 0x00
TX_ADDR		= 0x0000000000
RX_PW_P0-6	= 0x00 0x00 0x00 0x00 0x00 0x00
EN_AA		= 0x00
EN_RXADDR	= 0x00
RF_CH		= 0x00
RF_SETUP	= 0x00
CONFIG		= 0x00
DYNPD/FEATURE	= 0x00 0x00
Data Rate	= 1 MBPS
Model		= nRF24L01+
CRC Length	= Disabled
PA Power	= PA_MIN
ARC		= 0

s'il est vu:

SPI Speedz	= 10 Mhz
STATUS		= 0x0e RX_DR=0 TX_DS=0 TX_DF=0 RX_PIPE=7 TX_FULL=0
RX_ADDR_P0-1	= 0x544d52687c 0xabcdabcd71
RX_ADDR_P2-5	= 0xc3 0xc4 0xc5 0xc6
TX_ADDR		= 0x544d52687c
RX_PW_P0-6	= 0x01 0x01 0x01 0x01 0x01 0x01
EN_AA		= 0x3f
EN_RXADDR	= 0x02
RF_CH		= 0x4c
RF_SETUP	= 0x07
CONFIG		= 0x0f
DYNPD/FEATURE	= 0x03 0x06
Data Rate	= 1 MBPS
Model		= nRF24L01+
CRC Length	= 16 bits
