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.

That's a trap. It sounds like "buy ClearNav, and it will work with XCSoar", but it will not. Without cooperation, there _will_ be problems[*].

([*] = it will work only if you emulate all CAI302 firmware bugs, bit by bit, and all timings are identical. The thing is, the CAI302 does not follow its own dataport communication standard. Not a big deal for XCSoar, we have workarounds, but a standards-compliant device will not work.)

We already know that ClearNav is not interested in XCSoar, and therefore I am mutually not interested in ClearNav. Connecting a ClearNav vario to XCSoar is explicitly not supported.

Though I hope ClearNav changes their minds. (It's up to their customers to highlight the importance of connectivity to them, or to choose a vendor that is open enough for one's personal taste.)
