Select Traffic sharing

 

Enable GDL90 Traffic sharing, set EasyVFR as EFB application

Note the vertical limitations the SafeSky app imposes! This overrules the vertical proximity settings in EasyVFR 4 

 

Start EasyVFR4, no additional settings are required provided EasyVFR 4 runs on the same device as the SafeSky app, or the device running EasyVFR 4 is using the same WiFi network as the device that has the SafeSky app running :

 

on Apple iOS and iPadOS you can tell the correct functioning of SafeSky and EasyVFR 4 by the blue background of the time at the system bar, and the number of traffic items EasyVFR4 has received over the last 30 seconds.
