This keeps the logs intact (as far as possible) 2) when maximised check if previously connected to a WiFi hotspot and revert to that. Is there no way to do a “keep alive” or ping?

m Group: Forum Members Posts: 158, Visits: 1	My last post I've linked to a few developers pages showing use of wifi when in background mode. Can you get Tim to have a look at these and post back on the forum either way? I've still not seen a comment on whey SD does not show up as an App that supports IOS Background Application Refresh - can you confirm why not?? (ps l do love your product so please don't take my constant badgering as an annoyance. I am a member of PPL/IR and am wanting to get to the bottom of this so i can convince everyone that SD can be used alongside IFR apps inflight )

Thanks, after several pages, of confirming BAR doesn’t work on WiFi! Hannah tells me that you’ve kindly worked on a patch to get it to resume when the app Is brought into foreground - is that correct? Could I ask for an additional tweak? Have an option (user selected in configuration or timed) that automatically switches to location services if in background mode?

Group: Forum Members Posts: 8K, Visits: 9.1K	We have removed the code which eventually gave up on a UDP connection to PilotAware for the next version of SkyDemon. In future, SkyDemon will sit there waiting for data to be received forever. It's not clear whether Apple would allow dynamic switching to their location services when the app is being put to sleep, an action which would itself trigger their special background mode to keep the app awake. It would be more of a fundamental architecture change for SkyDemon than the "tweak" you optimistically describe, so I'm afraid it's not on the cards regardless.
