Fun/Send PC screen to SU2 Here a java code snipped that takes a screenshot of your PC desktop and sends it to a Nokia SU-2 (or any other bluetooth JPEG viewer ...) {code} package scr2su2; import de.avetana.javax.obex.ClientSession; import de.avetana.javax.obex.HeaderSet; import de.avetana.javax.obex.Operation; import de.avetana.obexsolo.OBEXConnector; import java.awt.Rectangle; import java.awt.image.BufferedImage; import java.io.ByteArrayOutputStream; import javax.imageio.ImageIO; public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here try{ for(int j=0;j<100;j++){ // 100 times change this java.awt.Robot roby = new java.awt.Robot(); Rectangle screenRect = new Rectangle(0,0,640,480); // SU2 can only handle images up to VGA resolution BufferedImage img = roby.createScreenCapture(screenRect); ByteArrayOutputStream baos = new ByteArrayOutputStream(); ImageIO.write(img, "jpeg", baos ); // change the address to the bluetooth address of your SU2 String adr = "btgoep://0002EE9340ED:13;authenticate=false;encrypt=false;master=false"; ClientSession cs = (ClientSession) OBEXConnector.open(adr); HeaderSet hs = cs.connect(cs.createHeaderSet()); byte[] text = baos.toByteArray(); hs.setHeader(HeaderSet.NAME, "test.jpg"); hs.setHeader(HeaderSet.TYPE, "image/jpeg"); //hs.setHeader(0x49, text); // if everything fits inside a packet, the data can be packed in the PUT command hs.setHeader(HeaderSet.LENGTH, new Long(text.length) ); Operation po = cs.put(hs); System.out.println("put...."); java.io.OutputStream os = po.openOutputStream(); int of=0; do{ int le = 64; if(le+of>text.length) le=text.length-of; os.write(text,of,le ); os.flush(); of+=le; }while(of<text.length); po.close(); cs.disconnect(null); cs.close(); // you should add a Thread.sleep(..) here because SU2 can't handle that otherwise } } catch (Throwable e) { e.printStackTrace(); } } } {code} The code above needs BlueCove and AvetanaOBEX in your classpath to work. You should change the bluetooth address to the address of your SU-2. Now you can watch your PCs desktop on your TV. Sending stuff to your SU-2 you should send the bytes in small chunks and set the type to image/jpeg. 2005-08-06 10:42:41.524 2005-08-06 10:42:41.524
