Major Traccar Client update
The log doesn't seem to show anything unusual. There are just no entries until I use the phone again. This is one example from a walk (with my notes). On iPhone, probably Testpilot build 140. Settings were: Highest, 10m, 20sec, no angle, 300heartbeat, offline buff, no stop detect.

I also tried the latest Apple Store version yesterday (10.0.6). I notice it had the permission for 'Motion and Fitness' applied.
That worked fine for a walk of 90 minutes which is promising.
The one of App Store is the latest version if there are some issues with it, please report. I would recommend using a separate thread though. At this point the app is officially released.
Thanks for the answer. I'm calling a php file with it, in which the data has been sent in json format with a POST request so far. What protocol is it sending now?
Ok, I see. It became a query string instead of json. Then I'll switch my server to that.
But why isn't it sending speed data?
Also, a previously resolved bug has returned: if the application goes into the background, it becomes passive and does not send data.
Please create a separate thread if you want to continue the discussion.
I am experiencing a very similar issue on a Xiaomi phone with HyperOS.
Traccar Client works for some time, but after entering stationary mode it stops location updates and does not resume tracking correctly in the background. This creates long gaps and large straight-line jumps in the route history.
The server is working correctly and returns:
Upload response 200
The relevant client log is:
StationaryEnter: pausing
Wakelock released
Location updates stopped
Service destroyed
Later, when the application tries to restart tracking, Android blocks it:
Service start blocked:
android.app.BackgroundServiceStartNotAllowedException:
Not allowed to start service ... app is in background
Manually disabling and enabling Continuous Tracking restores tracking temporarily.
My settings:
- Location accuracy: Highest
- Distance: 50 m
- Interval: 30 s
- Stationary interval: 180 s
- Offline buffering: enabled
- Wake lock: enabled
- Location permission: Allow all the time
- Battery usage: unrestricted
This problem started recently after the application update. The server and Home Assistant configuration have not changed.
Could this be the same regression reported in this issue?
"Service destroyed" log is the key here. The system stopped the service for some reason. It shouldn't be doing it.
We have changed the protocol, so your server probably needs to be updated.
