按键回调函数相关求助

AILI

功能：在APP端设置了4个按键，按下每个按键端口输出不同的数组

问题：a,b,c,d四个按键对应输出A,B,C,D四个数组，但实际上按下b会输出AB两个数组的数，按下c会输出ABC三个数组的数，按下d会输出ABCD四个数组的数。求助。。。
代码：
#define BLINKER_WIFI

#include <Blinker.h>
#include <Arduino.h>
char DATA1[]={0x55,0xAA,0x11,0x02,0x01,0x10,0x24,0x02};
char DATA2[]={0x55,0xAA,0x11,0x02,0x01,0x20,0x34,0x32};
char DATA3[]={0x55,0xAA,0x22,0x02,0x01,0x10,0x35,0x31};
char DATA4[]={0x55,0xAA,0x22,0x02,0x01,0x20,0x45,0x01};
char auth[] = "5b05dc85109b";//Your Device Secret Key
char ssid[] = "keke";//Your WiFi network SSID or name
char pswd[] = "123456789";//Your WiFi network WPA password or WEP key

{
   digitalWrite(5,HIGH);
   Serial.print(DATA4);
   Blinker.delay(300);
}
void setup() {
  Serial.begin(14400);
  pinMode(5,OUTPUT);
  Blinker.begin(auth, ssid, pswd);
  Button1.attach(Button1_callback);
  Button2.attach(Button2_callback);
  Button3.attach(Button3_callback);
  Button4.attach(Button4_callback);
}

void loop() {

  digitalWrite(5,LOW);
