huskylens can`t work

Hello
I'm studying Husky Lens
After a certain period of time
Husky lens doesn't seem to be able to call data values
So the digital Write output doesn't change
How do I solve this?
 

Here's the source code here

#include "HUSKYLENS.h"

HUSKYLENS huskylens;

//HUSKYLENS green line >> Pin 10; blue line >> Pin
void printResult(HUSKYLENSResult result);
int out = 9;
bool flag_led = 0;
int led_cnt = 0;

void setup() {
 Serial.begin(9600);
 pinMode(out, OUTPUT);
 pinMode(13, OUTPUT);
 Wire.begin();

 Serial.println("system start");
  while (!huskylens.begin(Wire))
   {
       Serial.println(F("Begin failed!"));
       Serial.println(F("1.Please recheck the \"Protocol Type\" in HUSKYLENS (General Settings>>Protocol Type>>I2C)"));
       Serial.println(F("2.Please recheck the connection."));
       delay(100);
   }

}

void loop() {
 if (!huskylens.request()) Serial.println(F("Fail to request data from HUSKYLENS, recheck the connection!"));
 else if (!huskylens.isLearned()) Serial.println(F("Nothing learned, press learn button on HUSKYLENS to learn one!"));
 else if (!huskylens.available()) Serial.println(F("No block or arrow appears on the screen!"));
  while (huskylens.available())
       {
           HUSKYLENSResult result = huskylens.read();
           printResult(result);
       }    

   led_cnt++;
   if(led_cnt >= 50)
   {
     led_cnt = 0;
     flag_led ^= 0x01;

     digitalWrite(13, flag_led);
   }
   Serial.print(led_cnt);
   Serial.print("  ");

  delay(100);
  printResult(result);
 }

void printResult(HUSKYLENSResult result) {

 if (result.command == COMMAND_RETURN_BLOCK) {
   if(result.ID == 1) {
     digitalWrite(out, HIGH);
     Serial.println("on");
   }
   if (result.ID == 2){
     digitalWrite(out, LOW); 
     Serial.println("off");
   }
  
 }
}
