here is the code that im using.

#include "HUSKYLENS.h"
#include "SoftwareSerial.h"

// Create HuskyLens object
HUSKYLENS huskylens;
SoftwareSerial mySerial(12, 11); // RX, TX
//HUSKYLENS green line >> Pin 10; blue line >> Pin 11
void printResult(HUSKYLENSResult result);

void setNewName (String newname, uint8_t ID) {
while (!huskylens.setCustomName(newname, ID))
{
Serial.println(F("Custom name failed!"));
delay(100);
}

}
void setup()
{
Serial.begin(115200);
mySerial.begin(9600);
while (!huskylens.begin(mySerial))
{
Serial.println(F("Begin failed!"));
Serial.println(F("1.Please recheck the \"Protocol Type\" in HUSKYLENS (General Settings>>Protocol Type>>Serial 9600)"));
Serial.println(F("2.Please recheck the connection."));
delay(100);
}
// Short delay to let HuskyLens stabilize
delay(100);

// Change detected face names
setNewName ("John", 1);

}

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!"));
else
{
Serial.println(F("###########"));
while (huskylens.available())
{
HUSKYLENSResult result = huskylens.read();
printResult(result);
}
}
}

void printResult(HUSKYLENSResult result){
if (result.command == COMMAND_RETURN_BLOCK){
Serial.println(String()+F("Block:xCenter=")+result.xCenter+F(",yCenter=")+result.yCenter+F(",width=")+result.width+F(",height=")+result.height+F(",ID=")+result.ID);
