硬件快联设置网络

微信搜索“乐鑫信息科技”，关注，然后在商铺的Arikiss 设备，输入WiFi名称和密码，将WiFi名称和密码传到设备中

arduino代码如下

#include "Arduino.h"
#include "WiFi.h"
#include <HTTPClient.h>
#include <ArduinoJson.h>
#include <Preferences.h>Preferences preferences; 
String PrefSSID, PrefPassword; void smartConfigWIFI()
{WiFi.mode(WIFI_AP_STA);WiFi.beginSmartConfig();//Wait for SmartConfig packet from mobileSerial.println("Waiting for SmartConfig.");while (!WiFi.smartConfigDone()) {delay(500);Serial.print(".");}while (WiFi.status() != WL_CONNECTED) {delay(500);Serial.print(".");}preferences.begin("wifi", false);preferences.putString( "ssid"         , WiFi.SSID());preferences.putString( "password", WiFi.psk());preferences.end();Serial.println("SmartConfig done, restarting..");delay(2000);ESP.restart();
}void initWifi()
{Serial.println();Serial.print("Try to connection original wifi...");//read wifi in NVSpreferences.begin("wifi", false);PrefSSID          =  preferences.getString("ssid", "none");PrefPassword      =  preferences.getString("password", "none");preferences.end();int count = 0;if( PrefSSID == "none" ){smartConfigWIFI();}WiFi.begin(PrefSSID.c_str(), PrefPassword.c_str());//Try to connection 5 secondswhile (WiFi.status() != WL_CONNECTED) {if(count==10) ESP.restart();delay(500);count++;Serial.print(".");}Serial.print("Connected! IP address: ");Serial.println(WiFi.localIP());  
}void setup() {Serial.begin(9600);initWifi();// Serial.print('start\n');// //Init WiFi as Station, start SmartConfig// WiFi.mode(WIFI_AP_STA);// WiFi.beginSmartConfig();// //Wait for SmartConfig packet from mobile// Serial.println("Waiting for SmartConfig.");// while (!WiFi.smartConfigDone()) {//   delay(500);//   Serial.print(".");// }// Serial.println("");// Serial.println("SmartConfig received.");// //Wait for WiFi to connect to AP// Serial.println("Waiting for WiFi");// while (WiFi.status() != WL_CONNECTED) {//   delay(500);//   Serial.print(".");// }// Serial.println("WiFi Connected.");// Serial.print("IP Address: ");// Serial.println(WiFi.localIP());
}String getUrl = "https://v1.hitokoto.cn/";DynamicJsonDocument doc(1024);void getData()
{HTTPClient http;http.begin(getUrl); //HTTP beginint httpCode = http.GET();if (httpCode > 0){// httpCode will be negative on errorSerial.printf("HTTP Get Code: %d\r\n", httpCode);if (httpCode == HTTP_CODE_OK) // 收到正确的内容{String resBuff = http.getString();Serial.println(resBuff);deserializeJson(doc, resBuff); //开始使用Json解析String uuid = doc["uuid"];Serial.print(uuid);}}else{Serial.printf("HTTP Get Error: %s\n", http.errorToString(httpCode).c_str());}http.end();
}
void loop() {// put your main code here, to run repeatedly:getData();delay(5000);
}

连接WiFi并且保存密码
