I've made a bluetooth game for the 6230 which works reasonably well.
However, I'm trying to get the two phones to disconnect at the end of the game..
I know this is possible, because Beach Rally II - the preloaded game on the 6230 can do this. You get the phone message '<other phone name> Disconnected'.
In my game, I don't get this message until the other phone shuts down the app.
As recommended in the nokia doc, I'm doing this when the game ends..
