LK8000 supports V7 since march 17th, 2012.
LX (both LXnav and LXnavigation, as well as most of other manufacturers) are
always very helpful and provide docs, specs, support, and sometimes also the
hardware itself to test on.
Sometimes we discover together bugs, and they are promptly fixed.
We dont have butterfly cooperation yet, but I am sure they are kind people
too.

The only problem with these devices is that they are too many, too flexible,
and too good!!

How do the V7 and Butterfly rate in terms of being open and do
they work with XCSoar and K8000??

These new intelligent variometers have a lot options that can be

system, which is not open and fully documented. I have discussed
with some variometer manufacturers about their data
communication protocols, and some of them either do not disclose
information, or do not give correct information. Some of them did
not even answer to my emails.

IMHO the value of your variometer will go down faster if it is a
closed platform. If it is open, and can connect with XCSoar and
LK8000 and others, you will benefit of all the new innovations
these
soaring SW gurus will develop.
