Im using an arduino and an hc-06 to communicate with an android. I'm trying to send int values over, but the android says it's receiving empty strings. This is my code:

```
#include <SoftwareSerial.h>
#define rxPin 11                     // define SoftwareSerial rx data pin  
#define txPin 10                     // define SoftwareSerial tx data pin  

#define trigPin 5
#define echoPin 6
SoftwareSerial blueTooth(rxPin, txPin); 

void setup() {
  Serial.begin (9600);
  blueTooth.begin(9600); 
  pinMode(trigPin, OUTPUT);
  pinMode(echoPin, INPUT);

}

void loop() {
  int duration, distance;
  digitalWrite(trigPin, LOW);  // Added this line
  delayMicroseconds(2); // Added this line
  digitalWrite(trigPin, HIGH);

  delayMicroseconds(10); // Added this line
  digitalWrite(trigPin, LOW);
  duration = pulseIn(echoPin, HIGH);
  distance = (duration/2) / 29;

   Serial.println(distance);                     
   blueTooth.print ((int)(Serial.read()));          

  delay(200);
}

```
