Roger,
We've not received a Wi-Fi enabled ADS-600B test unit from NavWorx to test and confirm this. They had us scheduled for a loaner, but that was postponed. I beleive they only have one test unit they send around so we are in line for it. It is working with the wired Serial connection and should work with the Wi-Fi, provided the Wi-Fi receivers make the handshack without issue.
I'll see if I can fly over to thier area and test, the issue it the ADS-600B is not a portable so it needs to be powered and semi-set up in plane. It's not just a simple charge or plug-in and test scenario. I'll circle back with NavWorx today and urge it's importance once again.
