PlainProtocol write 通过蓝牙发送 接收端数据时而为null

#include <PlainProtocol.h>

PlainProtocol mytest(Serial, 57600);

const int waterPin = 10;

void setup() {
  mytest.init();
  pinMode(waterPin,INPUT);
}

void loop() {
  int t_analogValue;//analog
  t_analogValue = analogRead(0);   //connect Steam sensors to Analog 0
  int t_digitalValue = LOW; //default digital low
  t_digitalValue = digitalRead(waterPin);

  //low is sending
  if(t_digitalValue == LOW){
    mytest.write("T_A|T_D",t_analogValue,t_digitalValue);//send analogValue and digitalValue
  }
  delay(1000);
}

有时为乱码   我获取的16进制的

e01866fe 66000606 66fe6660 f818781e 18188600

mytest.sendFrame("T_A|T_D",2,t_analogValue,t_digitalValue);//send analogValue and digitalValue
