Hi there,
I searched and found Tracking/lines , but I still seem to be having some issues. I am able to perform line tracking with the screen off most of the time, but sometimes there are interruptions to the vertex collection, and sometimes (maybe if I lock it too quickly after starting the track?) there are no vertices taken at all.
Has anyone else experienced this? If so, any solutions? I have the erroneous distance protection on, and recently tried turning on the time requirement. I’m not confident that will have any affect but I will keep testing and see if I can reproduce the no-tracking issue.
Thanks, happy to be here 
Is this on iphone, android…? I haven’t had problems with tracking on android, leaving the phone locked in my pocket while I walk for a couple of hours. I do enable bot time and distance filtering (something like 5 minutes and 10-20 meters).
Does the tracking vertex count increase considerably if you disable the distance protection?
Sorry, I should have specified this was on Android. I was experiencing some terrible pings in my first testing, which was without a proper Bluetooth GNSS receiver. I should test tracking without it (with the receiver in use) to see how the vertices change.
My use case requires more vertex collection, I limit it to every 2sec. I will go for a walk around the block with the dog and try to recreate my issue.
Edit: to confirm, I do have success most of the time. It is inconsistent when it happens, which is why I want to see if anyone else notices it.
Ah I see! Much more demanding scenario than what I use (I just use the phone’s gnss), so your walk with the dog should recreate something more similar to what I know.
Regarding the intermittence, maybe you can check the logs of the received data to help diagnose what might be happening. Check this page of the documentation regarding how to create a “vertex log layer” for example.
very good suggestion. My track on the dog walk worked perfectly, I will have to keep trying to reproduce it. I will try setting up the vertex log for tracking as well so I am ready for the next occurrence.
