Building a Java ME Bluetooth chat in 12 minutes...

Posted by brunogh on April 2, 2008 at 8:05 PM PDT

As it was announced before, Marge 0.5 is out. In this post, I am going to demonstrate an interesting new feature called AutoConnect. AutoConnect is indeed to automatically connect Bluetooth devices. It has some limitations due to some bad implementations and has some scenarios that maybe it is not the best option, but still very interesting and is definitely awesome to make something with a few lines of code! For more information about the new release and this feature, please check

So, nothing better than show a video... [sometimes I think I should have done cinema :) ]... Anyway, if you have not seen any Marge videos yet, try "Project Marge Interview", "My laptop is detecting my presence" and "Giant Blue Pong (my Bluetooth Atari)". Too much talk, take a look at the new "Building a Java ME Bluetooth chat in 12 minutes..." too. Could you not understand what happened in Netbeans code editor? Neither do I!!! It is better to download the full video (30MB). Hope you enjoy!

Go ahead! Marge your Bluetooth app!

Hi, could you make a tutorial on how to use the normal one, not the automatic? I can't seem to get it to work, and the BlueChat gives an error on my netbeans, so i can't see how that one is done.. Thanks for having this project, its really amazing the apparent difference between this programs and the regular ones without Marge =D Marge FTW

Hello ricardo, thanks for the words. Have you checked Cheers,Bruno
