Linkit 7697 cannot connect to blynk

Hi Blynkers
I come from Taiwan
My English is not very good, but I still want to ask everyone.

I originally used linkit 7688. Unfortunately, he is malfunctioning.
soI bought linkit 7697
Currently I want him to upload temperature and humidity to blynk.
But I don’t know how to get him to connect to blynk
At the moment, I can only let him connect to wifi.
Have you tried to let him connect with blynk?
Or which one should I choose in the template?
https://examples.blynk.cc/?board=ESP8266&shield=ESP8266%20WiFi&example=More%2FDHT11
Or can I provide any reference materials for me to study?
thanks

Attach the program I modified from 7688

#define BLYNK_PRINT Serial
#include "DHT.h"
#include <LWiFi.h>
#include <BlynkSimpleYun.h>
#define DHTPIN A1     // what digital pin we're connected to
#define DHTTYPE DHT11   // DHT 11
DHT dht(DHTPIN, DHTTYPE);
BlynkTimer timer;

char _lwifi_ssid[] = "Xiaomi_6AA3";
char _lwifi_pass[] = "59902146";
char auth[] = "8320b6af67fd49f4b6f5a6b727f5d573";

void setup() {
  Serial.begin(9600);
  Serial.println("DHTxx test!");
  while (WiFi.begin(_lwifi_ssid, _lwifi_pass) != WL_CONNECTED) { delay(1000); }
  Serial.println("連線成功");
  dht.begin();
}

void loop() {
  // Wait a few seconds between measurements.
  delay(2000);

  float h = dht.readHumidity();
  float t = dht.readTemperature();
  // Check if any reads failed and exit early (to try again).
  if (isnan(h) || isnan(t)) {
    Serial.println("Failed to read from DHT sensor!");
    return;
  }

  Serial.print("Humidity: ");
  Serial.print(h);
  Serial.print(" %\t");
  Serial.print("Temperature: ");
  Serial.print(t);
  Serial.println(" *C ");
  Blynk.virtualWrite(V5, h);
  Blynk.virtualWrite(V6, t);
  Blynk.run();
  timer.run();

}
