This tutorial will help you transmit and recieve to a serial device using your Liquidware Android kit and Ambrosia Card

This could be useful to interface Android applications to serial devices like Arduinos, Accelerometers, and other sensors.

 

 

  • In your Skeleton app add this code to begin serial:
import android.serial.*;
....

SerialManager Serial; 


Serial = (SerialManager) getSystemService(Context.SERIAL_SERVICE);

 

  • In your Skeleton app add this code to receive serial:
/* Handle Serial messages */
SerialStatus.SerialMsgListener sl = new SerialStatus.SerialMsgListener() {
 public void onSerialMsgReceived(String sMsg) {
  /* Handle the message.. */ 

  Log.v("SkeletonSerial", sMsg);
 }
};
Serial.addSerialMsgListener(sl);

 

  • Add this code to begin serial
Serial.begin("ttyUSB0", 9600);

 

  • In your skeleton app add this code to transmit serial: 
Serial.print("U");

 

  • Upload your code

  • Plug in your Serial device.  I am using an Arduino.

   

 

  • On the Arduino I used this sketch which will blink an LED when I send a "U":
