EchoBox is a simple client-server application demonstrating audio transfer over Wi-Fi from desktop to J2ME phone.
It was written just to test out J2SE-J2ME interaction. You'll need a Wi-Fi phone to use it because it looks like phone networks block open ports over-the-air.
First start both client (double-click EchoBoxApp.jar) and server applications, then type the phone's IP address into "Phone IP" on the desktop application. Click record and record something, then send to the phone. You should hear the recording that was sent from the desktop application. Don't record for too long because the audio file is raw PCM, so just do about 10 seconds.
Requirements:
· A Wifi J2ME phone (or a Wireless Toolkit such as Sun's WTK) and the Java Runtime Environment installed on the computer
