Why since LV 8.1 the GPS acquisition is more longer ?

[Ludovic THEBAULT]

Hello,

Why since Livecode 8.1, GPS acquisition is more longer than Livecode < 8 on mobile ?

On the same place, my mobile  get coordinates within few seconds with the app compiled with LV < 8.1 but get coordinates after more than 15 seconds (more than one cycle on my script) if the app is compiled with LV > 8.1

Any ideas ?

Thanks

Here my script : 

################################

on opencard :
if the environment is "mobile" and mobileCanTrackLocation() is "true » then

	if "iphone" is in the platform then

		get mobileLocationAuthorizationStatus()

		if "denied" is in it or "restricted" is in it then ...

	end if

	mobileStartTrackingSensor "location"

	wait 10 milliseconds with messages

	put getcoord() into old « coordinates »

	 mobileStopTrackingSensor « location »

end if
	
end opencard

################################

on locationChanged pLatitude, pLongitude, pAltitude

	set the coordonnees of this stack to pLatitude & tab & pLongitude & tab & pAltitude

end locationChanged


################################

function getCoord
	get the coordonnees of this stack

	put mobileCurrentLocation() into tLocation    

	if tLocation is an array and tLocation["latitude"] <> "" and tLocation["longitude"] <> "" then

		return tlocation

	else	

		if the coordonnees of this stack <> it then 

			return the coordonnees of this stack

		else
			put the seconds into timeout
			repeat forever
				if the seconds - timeout > 15 then 
				answer « Is too long, Retry ? » with « Yes » or « No"
				if it is « No » then
					 mobileStopTrackingSensor « location"
					exit repeat
				else
					 mobileStopTrackingSensor « location »
					wait 200 milliseconds with messages
					mobileStartTrackingSensor "location"
					put the seconds into timeout ### new cycle
				end if	
				put mobileCurrentLocation() into tLocation    
				if tLocation is an array and tLocation["latitude"] <> "" and tLocation["longitude"] <> "" then  
					exit repeat
				else
					put mobileSensorReading("location",true) into tlocation
					if tLocation is an array and tLocation["latitude"] <> "" and tLocation["longitude"] <> " » then exit repeat

				end if	
			end repeat
			if tLocation is an array and tLocation["latitude"] <> "" and tLocation["longitude"] <> " » then 
				return location
			else return the coordonnees of this stack ### old coordinates
		end if
	end if
end getCoord
