I am developping an application that represents meassurements by a sensor on an android OS. The sensor contains the meassurements taken by moving. The sensor has a connection with Android through bluetooth. I switched the bluetooth on both the android phone and sensor on, and the phone recognized the sensor through its MAC address (this is the option of the phone itself). So the 'connection' is there, but how do I start from scratch with obtaining the data from that sensor? Does someone has an step by step example of how to do this? (I really don't have any experience in it, only basic Java).
