Thaks for the reply. Yes, I have the 4500 which does provide Wind Direction data.
Also, can you reply to these questions I posted earlier? I am coming from the iphone version of Shooter to the Android...........
I have been using your shooter app on my iphone and ipad. It is terrific. The calcualtions are spot on and the interface is very confortable.............

Just because your Kestrel shows the wind direction and just because you may be able to import it via your computer using their software doesn't mean its available to me over the serial BT connection. Kestrel has a very basic serial BT API and it doesn't include wind direction in it's output.

Sean, this is not correct. If you use <span style="font-weight: bold">S</span> command (Output a Full Data Snapshot), Kestrel 4500 <span style="text-decoration: underline">will</span> provide you with compass (and true) direction, wind speed - and crosswind and headwind components of the wind. Even if you use <span style="font-weight: bold">O</span> or <span style="font-weight: bold">P</span> there is wind data and Compass Direction (for Kestrel 4500)... <span style="font-style: italic">So use what gives you the most info - command <span style="font-weight: bold">S</span>.</span>
As a thought, you could use the heading/direction from the Kestrel for Coriolis heading.
The BT interface (which is exactly equivalent to serial/USB - those units that come with BT don't have USB, and vs versa) is pretty basic - but retrieving data snapshots is pretty basic too, complexity isn't needed. And whatever one can import (via BT) to a computer - is importable via BT to other BT hosts such as Android phones (which aren't distinguishable from a computer as far as Kestrel is concerned).

The Kestrel outputs a line of column headings, followed by a line of units, followed by lines of comma separated the data.
