title: Microsoft Bluetooth Stack RSSI Workaround
body: <p>I finished an implementation of a bluetooth application for a robot. Server sided I used Windows 7 as OS with the MS-BT-Stack as well as C# as language with the "In the hand"-bluetooth library.<br />
  The target was to connect the robot via bluetooth when it's in range.<br /></p>
  
  <p>Just as extension I tried to read the signal strength to determine how far away the robot is (estimated). Okay, while googling (and searching on stackoverflow too^^), I found out that you can't do that with my used BT-stack. Since that I tried to figure out a workaround to calculate or estimate the signal strength (or the distance).<br />
  Something like sending a byte over bluetooth and see how long is the answer-time. Although I haven't implemented it due to a lack of time but does anybody think that this is a good idea? Or has some other thoughts about the problem?<br /></p>
  
  <p>I really appreciate any input.<br /></p>
  
  <p>Thanks!<br /></p>
