jfitch. When the iPhone disconnected from the wifi stick, was the IGC file in either the iPhone or vario corrupt?

Not corrupt in the Vario. I didn't check the one in the phone on those occasions, as I rarely use the one in the phone. It is not secure for contests or records (I don't think?), and I already have one in the Vario and one in the Flarm. The WiFi connection is an additional source of faults not present in a wired serial setup (iGlide only does WiFi). Overall it has been pretty reliable for me, with occasional issues. Normally, if something goes wrong it happens right from the beginning when you turn everything on, and reconnecting fixes it. Once working for the flight, it normally stays working for the flight. When I was having the issues in flight, I attempted several things including power cycling the vario. Even in that instance, as long as you turn it back on within a few seconds, the IGC file is intact. In a race, you are allowed a maximum of 60 seconds between fixes, and a power cycle might push that.
