I had the Sky Echo 2 in use the first time at the 1st May for 3 flights.
At the first flight (1:15h) it worked great, perfect GPS position accuracy and showed me ADS-B traffic.
On the second flight (0:30h) the GPS connection of the SkyEcho 2 couldn't be established, so I flew with the iPad's GPS and without any traffic information.
On the third flight home (1:20h) again, the GPS connection of the SkyEcho2 was not working, so I began the flight with the iPad's GPS and tried to restart the SkyEcho2 several times inflight. after 30min the SkyEcho2 GPS connection began to work and so I switched in SD to fly with the SkyEcho, which then worked great on the GPS side and also on the traffic side.
I already wrote the uAvionix support regarding the GPS failures, but I am still waiting for an answer.
This day with the SkyEcho 2 was very disappointing for me, but WHEN it worked, it worked great! Even the Callsign is shown in SD.
In the moments, in which the SkyEcho2 GPS was not working, the GPS connection of the iPad was fine the whole time!
