Starting the GPS on Vivoactive in an App

Hi.

i'm bit lost about this. When the app starts i call the following:

Position.enableLocationEvents(Position.GPS_CONTINUOUS, method(:onPosition));

then where i need to pull the current Lat/Long i pull it from the current Info object.

this works fine in the sim (once you have set the data example going) but on the actual device it never seems to try and start the GPS when the application starts so it never records any location.

am i missing a command somewhere to get the GPS to start up when the app opens? (i have got activity recording working as well for this app and this jsut saves duration without any location info.)

No, that's all I do in my app, however, do you check for the GPS status to make sure it's established? I use this:

var gpsinfo = Pos.getInfo();
var gpsIsOkay = ( gpsinfo.accuracy == Pos.QUALITY_GOOD || gpsinfo.accuracy == Pos.QUALITY_USABLE );

Did you enable the positioning permission in the app properties -> connectIQ? If this permission is not enabled, it might work on the simulator, but not the watch.

It should throw an exception and crash the app if the appropriate permissions are not set.

Yes permissions were set in the app properties.

I loaded the positioning example from the SDK onto the device and it had the same issue. It was unable to turn onthe GPS and get a position.

I must be missing something to turn it on.

I have a compass widget in the app store that uses GPS when the magnetic compass is not available and the above call is all I do to enable GPS. I verified this during testing on a 920XT w/ 3.20 firmware.

What firmware version are you using on your Vivoactive? Have you somehow disabled GPS in the device settings?

v2.60 that was released on the 25th of march

How long are you waiting for a position on the real device? On a VA, I've seen it take a bit of time - maybe 10-20 seconds at times. The simulator gets the position as soon as you simulate the data with no real delay.

is this actually a widget and not an app? Seems that if you have GPS off in the va settings, you can use GPS from an app, but not from a widget.

I see 2.70 was released today. will update later and see if that helps things.

If the example from the SDK isn't working, then it's not likely to be something your missing. So it will either be your GPS can't find a signal, or maybe you've got a faulty device?
