[solved] Getting the last known position from GPS
I need the last known position from my GPS even if it is not turned on.
Viewranger is a program in which I can see my last known position even if the GPS receiver is turned off.
How to do so in QML, maybe with the PositionSource element ?
Your idea is, I think, the easiest and the one which is the least complicated.
I am not sure but I really think that these positions are already stored on my device.
In the example, I used Viewranger to see where I was when I turned off GPS but I don’t remeber having run Viewranger when I turned GPS off.
Ok, but then, with your solution, I always have to keep my program running in the background with a timer to cyclically write the GPS coordinates in the file if they are !==NaN.
Then I think of adding my program to the system startup, but how to do so ?
Maybe a new topic would be appropiate to ask this.
My idea was running my app always in the background and saving the GPS’s coordinates in a text file if they are valid (that’s what I meant with “!== NaN”).
This app should work as a “helper” app.
Then when my actual program is run and not GPS is turned on, it checks the file and gets the position.
But I think you are right that running the program in the background might harm the battery.
