Bonjour J-M-L

Le pire est que, il y a longtemps, j'ai étudié tout ça :woozy_face:, je refais une version TCP.

Concernant ESP-NOW, j'ai des soucis de compilation:

   62 |   esp_now_register_recv_cb(OnDataRecv);
      |                            ^~~~~~~~~~
      |                            |
      |                            void (*)(const uint8_t*, const uint8_t*, int) {aka void (*)(const unsigned char*, const unsigned char*, int)}

Compilation error: invalid conversion from 'void (*)(const uint8_t*, const uint8_t*, int)' {aka 'void (*)(const unsigned char*, const unsigned char*, int)'} to 'esp_now_recv_cb_t' {aka 'void (*)(const esp_now_recv_info*, const unsigned char*, int)'} [-fpermissive]```

Le programme:

#include <esp_now.h>
#include <WiFi.h>
const char nom[10]="Master"; 
uint8_t broadcastAddress[2][6] = {
  {0x2C, 0xF4, 0x32, 0x15, 0x52, 0x22}, //station0
  {0xA0, 0x20, 0xA6, 0x08, 0x20, 0xD9}  //station1
};// REPLACE WITH RECEIVER MAC ADDRESS

// Structure example to send data
// Must match the receiver structure
typedef struct struct_message {
  char a[32];
  int b;
  float c;
  String d;
  bool e;
} struct_message;
struct_message myData;
struct_message dataRcv;

unsigned long previousTime=0;


// callbacks for sending and receiving data
void OnDataSent(const uint8_t *mac_addr, esp_now_send_status_t status) {
  Serial.print(F("\r\nMaster packet sent:\t"));
  Serial.println(status == ESP_NOW_SEND_SUCCESS ? "Delivery Success" : "Delivery Fail");
}

void OnDataRecv(const uint8_t * mac, const uint8_t *incomingData, int len) {
  memcpy(&dataRcv, incomingData, sizeof(dataRcv));
  Serial.print("\r\nBytes received: ");
  Serial.println(len);
  Serial.print("From slave: ");
  Serial.println(dataRcv.a);
  Serial.println();
}
void setup() {
  // Init Serial Monitor
  Serial.begin(115200);

  // Set device as a Wi-Fi Station
  WiFi.mode(WIFI_STA);

  // Init ESP-NOW
  if (esp_now_init() != ESP_OK) {
    Serial.println(F("Error initializing ESP-NOW"));
    return;
  }
  Serial.print(F("Reciever initilized : "));
  Serial.println(WiFi.macAddress());
  
  // Define callback functions
  esp_now_register_send_cb(OnDataSent);
  esp_now_register_recv_cb(OnDataRecv);

  // Register peer
  esp_now_peer_info_t peerInfo;
  peerInfo.channel = 0;
  peerInfo.encrypt = false;
    
  memcpy(peerInfo.peer_addr, broadcastAddress[0], 6);
  if (esp_now_add_peer(&peerInfo) != ESP_OK){
    Serial.println("Failed to add peer");
    return;
  }

  memcpy(peerInfo.peer_addr, broadcastAddress[1], 6);
  if (esp_now_add_peer(&peerInfo) != ESP_OK){
    Serial.println("Failed to add peer");
    return;
  }
  
}

void loop() {
  if((millis() -previousTime)>5000){ 
    // Set values to send
    strcpy(myData.a, nom);
    myData.b = random(1, 20);
    myData.c = 1.2;
    
    myData.e = false;
  
    // Send message via ESP-NOW
    myData.d = "Slave0";
    esp_err_t result0 = esp_now_send(broadcastAddress[0], (uint8_t *) &myData, sizeof(myData));
    

    myData.d = "Slave1";
    esp_err_t result1 = esp_now_send(broadcastAddress[1], (uint8_t *) &myData, sizeof(myData));
    previousTime=millis();
  }
}

La solution que j'ai trouvé sur le net est de faire un downgrade de la carte ESP32, or le downgrade ne se termine pas :woozy_face:
J'ai vu ici que vos aviez réussi à compiler sans erreur, avec quelle version?

Merci par avance.
