M5StickC(ESP32)にいちばん強いWifiに接続してほしい(WiFiMulti)

WiFiMultiというクラスがありましたとさ。

wifimulti.cpp

#include <Arduino.h>
#include <M5StickC.h>
#include <WiFi.h>
#include <WiFiMulti.h>

WiFiMulti wifiMulti;

#include "secret.h"

void setup() {
  M5.begin();
  wifiMulti.addAP(SSID1, PASSPHRASE1);
  wifiMulti.addAP(SSID2, PASSPHRASE2);
}

void loop() {
  M5.Lcd.setRotation(1);
  M5.Lcd.fillScreen(BLACK);
  M5.Lcd.setCursor(0, 0);
  M5.Lcd.setTextColor(WHITE);
  M5.Lcd.setTextSize(1);

  printf("WiFiMulti connecting...\n");
  M5.Lcd.printf("WiFiMulti connecting...\n");

  if(wifiMulti.run() == WL_CONNECTED) {
    printf("CONNECTED: ssid=%s localIP=%s\n", WiFi.SSID().c_str(), WiFi.localIP().toString().c_str());
    M5.Lcd.printf("ssid=%s\n", WiFi.SSID().c_str());

  }
  WiFi.disconnect();
  printf("disconnected.\n");
  M5.Lcd.printf("disconnected.\n");
  delay(1000);
