you can use the phone bluetooth.. what you need is the bluetooth libraries.. i believe, by default when you download the android sdk, the libraries will be in the app developmet tool.. what you need to do just use the "import" command and you ready to use bluetooth function on your phone. at the hardware side you need the blutooth module.. phone bluetooth will be act as virtual serial port. so at the hardware side coding, u need to use UART..
