A new setting "Send GPS (SkyDemon only)" has been added. If you want to use AvTraffic with SkyDemon, switch this on.
It's always been an issue with some EFBs that when connecting to a GDL90 device, you need to start AvTraffic before you start your EFB. Now, if AvTraffic has a problem connecting to the device it will warn you.
A new GDL90 help page has been added to clarify why this can happen and what to do about it.
