Default XCSoar and Wind

Thanks, I haven't done that many turns since trying this out. Next time...

If you have no airspeed information the only way to calculate the wind is
by measuring the drift of your circle in circling mode. In my experience
XCSOAR wants 4-5 thermalling turns before it calculates the wind.

Apparently my question is not understood by the developers or XCSoar
does not independently calculate and display wind.

I do not want to manually enter wind based upon a guess of what it is.
I want XCSoar, running on a Dell Streak 5, with no external device
connected, to calculate and display the wind.

Does XCSoar do that? How to I make it do that? I have tried all of the
suggestions and, without an external source, i.e., CAI-302/Bluetooth, I
get no wind.

OK, more speculation about how this works. Looking at the code.

In =6.8, if wind is set to Manual (not Auto), and External wind is

present then External is used. If you then set wind manually, that
overrides the External wind.
In the Modal, once you select wind manually, a "Clear" button appears

(it is not there before). Select 'Clear' once you are done with the

Manual
wind and it goes back to using External (if present).
Hope that's how it is.

I asked that question yesterday on the XCSoar forums and Max (one of

the
main developers) replied.
Question:
Is the Manual option the same as disabled if an external wind source is

available?
Max's answer:
Yes. Good commit message, but bad naming in user interface.
