302 vs clearnav vario with XCSoar

Ramy,

It works. Wind from the CNv is displayed on the XCSoar device. I
haven't configured XCSoar to display head/tail wind, so I can't verify
that that works. I'll likely fly tomorrow and I'll try to remember to
check that for you. In the mean time, you might go to clearnav.net and
peruse the forum. You might find the answer there.

I've used the CNvXC for two years with a Streak/XCSoar and a 302 for 3

and two Bluetooth converters so my wife gets to use XCSoar when we fly.
XCSoar displays calculated winds, position, etc., from the CNv just
fine. XCSoar doesn't "support" ClearNav because ClearNav didn't or
wouldn't give them one to use for testing, but the CNv uses the 302
protocol.

The option to use externally calculated wind was removed in one of the recent XCSoar versions. So it also won't be available with a 302.

There were some issues with CNv serial communication but they were solved with software updates. It works well with XCSoar although it is officially not supported.

I'm also using CNv with digital display, linked to an Oudie Lite running XC Soar with the Cumulus cable. Works well.

Thanks Folks. The XCSoar external wind is still available in current release. I hope they will keep it as the 302 wind calculation was more accurate and updated faster than XCSoar internal wind calculation. This was true when I compared between the two few years ago, perhaps it was improved since. But since CN wind calculation suppose to be even better than 302, I want to make sure it is working with XCSoar external wind option. Another important parameter that 302 provides to xcsoar is true airspeed which is then used to calculate instant headwind/tailwind component. I want to make sure this is working as well before I decide to switch to CN Vario.
