title: Possible to read sensor values of phone just by bluetooth?
body: <p>When you connect bluetooth speakers or an external device you are connecting them using the Android/iPhones bluetooth settings. The android OS is doing this. Example:<a href="https://i.stack.imgur.com/6gfqi.jpg" rel="nofollow noreferrer">iPhone Bluetooth Menu</a></p>
  
  <p>These bluetooth speakers do not need an additional app that is required to download to work with the speakers. The phone seems to recognize the bluetooth device's profile as a headset/speaker and automatically gives any audio output to the speaker. </p>
  
  <p>Is it possible to replace the bluetooth speakers with a device that could read sensor values (GPS,Gyro,etc). For example, could you pair a device through the phone's bluetooth settings menu and then have sensor values of the phone given to that device.</p>
  
  <p>From my reading the device would have to have a "Health Device Profile" in order to read sensor information, but I have no idea what kind of chip to use, or if this is even possible.</p>
  
  <p>Any insight, suggestions, or knowledge would help a million. Thank you!</p>
