Another vario that works extremely well with XCSoar is the CAI302. Cambridge has published extensive and excellent protocol documentation before they (unfortunately) disappeared.



Its declared successor from ClearNav has no XCSoar support, and I suppose there will never be. ClearNav did not publish protocol documentation. I asked for documentation, but Richard Kellerman (who I'm not related to) rejected, saying his business is not interested in interoperability with XCSoar. Don't buy if you want to connect it to XCSoar (or any other free software)..



Cambridge is still around, although they are no longer doingany product development that I know of. I had my 302 repaired a couple of weeks ago.

While it is true that ClearNav is not interested in working with XCSoar, we will, as previously mentioned, support the CAI dataport communications standard for our upcoming CNv XC, so the XCSoar community, as well as everybody else already has our protocol. All CNvs sold to date may be software upgraded to XC version with dataport capability. See our website for more information or for more questions, please join our forum.
