Location: Order of enter and leave events unreliable

[Triangulix]

Hi

I'm using the Periodic Location Update trigger with several locations which do not overlap. In addition to the locations I need an "On Transit" state that is active when I'm outside of the known locations.

For example I want to switch between 3 states: Location A, On Transit and Location B.

When I move from location A to location B my phone sometimes ends up in the On Transit state because the event "enter location B" is triggered before the event "leave location A".

How could I ensure a clean transition betwen my states and a correct behavior of the On Transit state?

Hi,

Could you share the flow(s) you are using? Is the state "On Transit" only active for a very short amount of time or does this state persist for a few minutes until the trigger detects the next location?
Does your device return extremely coarse grained locations at times? Maybe you could mitigate the problem by using the minimum accuracy in the trigger.

I could send you the file in private but I cannot make it publicly available since it contains the positions of everything in my daily life.

There are transitions that can happen in less than 5 minutes and there are also transitions with several hours of on-transit time.

Yes, I already do that. The minimum precision filter is a great tool to reduce the location jumping when the location service has its occational drop-out but the reversing order of the events is a different problem.

Please send the flow(s) to info@automagic4android.com so I can take a look. Could you please also turn on Debug Log and Log to SD card until the problem occurs the next time so I can check the locations that the device detects.

Done.
