I so desperately want an app that lets me send and retrieve data from the Arduiono. As a version 1.0 app I expect more than this has to offer. Random crashes are frequent; the program restarts after the iPhone sleeps, losing the server address and ports number; there is no way to set a default ip and port so each time you start the program you have to re-enter your ip and port. This is certainly better than I could have written, so I commend the developer for his efforts. Hopefully the developer can work out the bugs so we will have a useful app.
