Erro compilando para a placa ESP32 Dev Module
Isso acontece quando coloco a biblioteca <WiFi.h>. Segue abaixo o código //-----WI_FI------
#include <WiFi.h>
const char* ssid = "meu_wifi"; const char* password = "12345";
// --- Bluetooth ---
#include <BLEDevice.h>
#include <BLEUtils.h>
#include <BLEScan.h>
#include <BLEAdvertisedDevice.h>
int scanTime = 5; //In seconds int nivelRSSI = -78; String dispositivosAutorizados = "10:39:17:0a:83:9c";
// --- Setup --- void setup() { Serial.begin(115200); conectarWifi(); Serial.println("Scanning..."); BLEDevice::init("");
}
Alguem sabe resolver?
Obrigado
