Hi Doug,
What version of PilotAware Software are you running? and on what device? The ‘current’ version of PilotAware is 20180520, but Lee has done a considerable amount of work since last May - in part to address disconnects, particularly (though not exclusively) with SkyDemon on Android devices.
The new software is due for release shortly, so it might be worth your while waiting for the release unless you are running an older version than 20180520, but if you could answer the above questions that will help.
Regards
Peter
