XCSoar With LNAV?

Hi Paul,

I don't have the time to develop the C+ skills to work on getting communication working between the L-NAV and XCSoar right now so I probably don't need the comm spec. I do know a pilot that has sent me something of the sentence structure that the L-NAV uses when communicating with the GPS Nav. I think that could possibly be used for getting data into XCSoar, but I haven't seen what all it can support.

I actually am quite happy leaving them disconnected from each other at this point. It allows me to leave XCSoar at a higher MC value or at least with a larger polar degradation buffer and experiment with the L-Nav MC value for more aggressive flying.

I do miss XCSoar having real-time wind info on a long glide though.

Hi Morgan,



By "L-NAV" do you mean an L-NAV and GPS-NAV combination? The L-NAV does not

send any data out to soaring flight software. It can send data to a

GPS-NAV. The GPS-NAV then sends the vario and GPS data out to the soaring

flight software.



I have the L-NAV and GPS-NAV dataport specification if you need it.

I have XCSoar running on a Dell Streak 5 and wanted to look into connecting

to the L-Nav in my glider. I have an IOIO board, but I believe the real

problem is that the L-Nav doesn't use the same protocol as the 302. XCSoar

essentially doesn't have the right driver for the L-Nav and so far none of

the developers have a need to configure a driver for the L-Nav or the

hardware to actually do it.



I suspect there are many potential users of that configuration, but it will

take a user with the drive and the skillset to augment the XCSoar code with

the necessary pieces to support the L-Nav.



Hans has some useful info on his website about connecting GPS data to an

L-Nav.

I have never used any of these products, but usually K6Bt and IOIO works



just like a cable would.

Can't you read the wind from the LNAV/GPSNAV and manually input it into
XCSoar? Not realtime, but pretty close.

Dan,

Yes, this is what I do if the situation warrants it, like wave or significant winds. Since I have the full L-NAV, GPS-NAV setup I can rely on that for final glide type info.

With 6+ of XCSoar, they really improved the easy of manual wind entry so you are correct, it's pretty trivial.
