I observe a strange behavior when using your application, under wifi coverage.
1/ Configured Traccar only NETWORK, my android does NOT turn on the GPS, and the positions are sent.
2/ Now configure Traccar MIXED mode. The App turns ON the android GPS, and positions are also sent.
3/ We are in (2), now if I turn off the android GPS, Traccar stops sending positions. I believe that it should work there as in (1)
How do you turn it off? If the same as before, you are turning all location providers, not only GPS.
Does or does not?
