m Group: Forum Members Posts: 158, Visits: 1	I was wondering if you can help - I'm being bounced between various people to find the answer! I have SD using PilotAware as GPS source all running on Ipad Mini ios12 If i minimise skydemon (switch apps or go to home screen) after about 5 mins (reproducible consistently and even at home when not flying) it will lose the GPS/Wifi from PaW. It comes up with the "no signal received for some time..." message I'm pretty sure its a PaW problem, as when i use the IPAD internal GPS and switch SD to background, SD still works fine, so I think its something to do with the wifi connection to PaW. Is there any logging in SD i can get it to prove if this is the case?

Hi TimT (and TimD) I don't think there is anything that can be done on our side - this may be a 'feature' of iOS that the Apps are put to sleep when the iPad is locked, and hence the timer in SD stops listening after not receiving data for some period thx Lee

Hi TimT (and TimD) I don't think there is anything that can be done on our side - this may be a 'feature' of iOS that the Apps are put to sleep when the iPad is locked, and hence the timer in SD stops listening after not receiving data for some period thx Lee Hi Lee Thanks for giving it some thought! I'd like to respond as follows: - What is the "timer in SD" set to? In my experience, this happens immediately, < 5 sec: Even if the iPad is locked, and then unlocked again within 3 sec, SD would have gone back to planning. If your timer was set to anything > 10 sec, I'd argue that the 'loss of listening'; is not related to the timer. - Why then is it so different, and so much more stable, if the GPS information is coming to SD via the inbuilt GPS of a cellular iOS devise, or via Bluetooth from an external GPS receiver? Wouldn't according to your initial analysis this (the device locking putting the app to sleep) cause the same problems regardless of how the GPS information to sent to the app? I can confirm that only in the PAW scenario SD loses track of where it is and reverts to planning mode if the iPad gets locked for a second.
