Conectando ao Wi-Fi...

my code is this

#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>
#include <WiFiUdp.h>
#include "cert.h"

const char* ssid = "ssid";             // SSID da rede Wi-Fi
const char* password = "pass";  // Senha da rede Wi-Fi
const char* server = "site.com.br";
const char* idEquipamento = "id";
const int numSensor = 1;
const double valorMedido = 28;
const int grandeza = 1;

const long utcOffsetInSeconds = 0;  // Ajuste de fuso horário em segundos

WiFiClientSecure client;

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Conectando ao Wi-Fi...");
  }
  
  Serial.println("Conectado ao Wi-Fi");

  // Inicializa o cliente NTP
  configTime(utcOffsetInSeconds, 0, "pool.ntp.org");
  
  BearSSL::X509List certRootCACert(cert_Cloudflare_Inc_ECC_CA_3);
  BearSSL::PublicKey publicKey(pubkey_sni_cloudflaressl_com);

  client.setTrustAnchors(&certRootCACert);
  client.setKnownKey(&publicKey);

  sendDataToServer();
}

void sendDataToServer() {
  if (WiFi.status() == WL_CONNECTED) {

    // Construct the URL with query parameters
    String url = "/target.php?var1=" + String(var1) + "&var2=" + String(var2) + "&var3=" + String(var3) + "&var4=" + String(var4);

    if (client.connect(server, 443)) {

well it is using the usb adapter to go direct on pc, and before i put the trust anchor and the knownkey it was working, but is was using "client.setInsecure()"

Error 28 is an addressing error. Usually some sort of bad pointer (including going outside an array bound).
Run the exception decoder to get the source lines on the call stack and see if that gives a clue where things went wrong.

5

how can i run the exception decoder, i googled about but i did not found anything about (probably i searched in the wrong way but ok)

6

I don't know if it works with V2 versions of the IDE. You may have to install version 1.8.19.

7

There's also an online decoder I stumbled across. I've never used it myself but it might be worth a try.

try adding some println statements to identify the code with the problem, e.g.

 // Inicializa o cliente NTP
  configTime(utcOffsetInSeconds, 0, "pool.ntp.org");
   Serial.println("configTime done");
  BearSSL::X509List certRootCACert(cert_Cloudflare_Inc_ECC_CA_3);
 Serial.println("BearSSL::X509List certRootCACert done");

i think i fixed it by redoing all the code, now it is connecting normally, i think ive put the wrong cert and it just crashed everything
