Problem Statement: Following this PilotAware (PAW) major software update, when "Go Flying" and" Use PilotAware" PAW often didn't want to connect. When "Go Flying", SkyDemon would initially produce a green bar with “Connecting to Device”, then after 5 to 10 sec SkyDemon comes with another white window, stating “No data has been received from your GPS devise for some time …” and reverts to Planning Mode.
This happened most of the time, but not always. When it didn't want to connect, there was not systematic way (such aw rebooting PAW, SD, and/or iPad) to convince it otherwise.
This may be a iOS specific problem, and it may not happen, or may not present itself the same way, on Android devices.
Solution: In the PAW configuration screen, there is a new setting "Device Connect Setting". This is by default set to "Auto".
-> Change this setting to "PilotAware (UDP)" and click "Save". This solved the problem for me.
