Just stumbled into this product on segelflug.de to interconnect various devices, including PDAs and Android.
Profits support the XCSoar program.

We have developed low-cost electronics to
connect FLARM devices, variometers and
loggers with PDAs and Android phones
running soaring computer software like
XCSoar, Winpilot etc. This is a non-
commercial project of glider pilots and
electronics hobbyists, and the original
idea was to support XCSoar development
team.
