Using an iPad mini, Skyecho 2, Safesky and Skydemon. After connecting Safesky to the Skyecho Wifi and minimizing, when I select ‘Go Flying’ and GLD 90 device on Skydemon I get the error message “Address Already in Use”. I have tried every possible start up sequence and tried multiple iPad settings. Very occasionally it will work but when I shut down and restart I am back in the same loop.. Also ccasionally the Wifi link to Skyecho drops despite being on the ground. Things work if I use ‘location services’ for Safesky instead of Skyecho. I am trialing premium membership but this seems way to unreliable to risk flying with. ---

Hi Tristan - is there any update on this topic. Everything seems to work when I connect Safesky to Location Services on the iPad mini and traffic shows on Skydemon. If I try to use the Skyecho 2 I always get the “Address Already in Use” message. ---

Same problem here. The “Address already in use” message usually appears in SkyDemon after the first SafeSky “Take Off” after connecting to the SkyEcho 2. I then have to stop SafeSky and tap “Take Off” again. After that, SkyDemon can connect without any problems. Skydemon 4.3.2.453, Safesky 3.0.34, iPad mini (5th generation). iPad OS 26.5.2 ---

I can confirm DavidFlint message. Seeing this exact same issue ob iPad Mini 7 (IOS 26.6.1), SkyDemon (version 4.3.2) and SafeSky (version 3.0.35) with my SkyEcho II. ---

Dear SafeSky Support Team, I am experiencing the same problem when trying to use SafeSky together with SkyDemon and a SkyEcho 2 on the same iPad. My intended setup is: SkyEcho 2 → SafeSky → SkyDemon However, when I start SkyDemon and select “Go Flying → Use GDL90 Compatible Device”, SkyDemon reports: “Not connected. Address already in use.” I have carried out the following troubleshooting steps: 1. Tested SkyEcho 2 directly with SkyDemon, without SafeSky running. This works correctly. 2. Completely closed both SafeSky and SkyDemon and restarted them in the recommended order: Could you please advise whether this is a known issue with SafeSky/SkyDemon on iPadOS, or whether there is a setting or workaround required to prevent the apparent GDL90/UDP socket conflict? Thank you very much for your support. Kind regards, FrequentFlyer
