I am not a technical specialist. But you can check in the SafeSky preferences that GDL90 is enabled and that Automatic Device Discovery is also enabled. Then, in SkyDemon, click on Go Flying and choose Use GDL90 Compatible Device. I am not sure, because I don’t use IOS, but I think you have to be on version 13 of IOS. Have nice flights ---

“But you can check in the SafeSky preferences that GDL90 is enabled and that Automatic Device Discovery is also enabled” i cant find these options, do i need to have a full subscription to access this? ---

For SafeSky to show traffic on SkyDemon you need subscription ---

Yes I have. Worked it out. On Skydemon it was just waiting for a connection. Turns out it’s because I had set it up to merge traffic from skyecho into the safesky signal, but skywcho wasn’t connected. It waits till both sources are available before it connects. Now it seems to be great 👍. Thanks for replying… ---
