Settings used with the GPS Connector app for USB connection: generic chip, 115200 baud

I use OruxMaps to navigate when boating. Some of the paths I take have many turns. I have been getting by with my phone's 1Hz update rate, but the latency is annoying when making turns and the map orientation lags. I decided to try faster data from the Bad Elf Pro+, which has to be configured for 600 data points per minute.

I use the Android app "GPS Connector" by PilaBlu (Markus Hoffman) to provide mock location data. It can read both Bluetooth and USB data from the Pro+ and it has a window that lets one see NMEA strings. I started with Bluetooth and saw position fixes at 0.9s intervals, I think Bluetooth is throttling somehow, perhaps due to limited bandwidth? I switched over to USB and now see them at 0.1s intervals.

Some settings need to be changed to get the benefit of 10Hz data:

    Global Settings -> User Interface -> Miscellaneous UI -> Move the map instantly
    Global Settings -> User Interface -> Miscellaneous UI -> Maximum render speed
    Global Settings -> Sensor -> GPS ->  Minimum Time = 0
Global Settings -> Sensor -> GPS ->  Minimum Distance = 0

The display has a little more jitter to it but that beats an additional second of latency when you're following a complex path and need to know what's next.

Because of the high data rate I do not try to record a track, just observe location and TMG relative to the kml overlay that shows my planned route.

If anyone knows how to get 10Hz data using a Bluetooth connection I would like to know how you did it. Thanks!

I use the empty map to display routes and tracks when I go fishing. The empty map works offline and lets me view my routes at all zoom levels. I would like to display a white track on a black background for best viewing in full sunlight (and maybe less battery use). Is there a way to change the color of the empty map? Thanks!

Yes, that's it, exactly what I was looking for. As a bonus I also learned that I can organize my maps directory. Thanks!

I have two sets of layered maps that cover the same area. I get a prompt every time I change zoom asking me which I want to use. Is there a way to switch to one of the layered maps and not get prompted when I change zoom levels? Thanks!

I hope to give it a real workout this weekend.

Works great, just what I was hoping for. Thanks, Orux!

you can try that option in the new beta10 version (select the color in settings--user interface colors and the stroke in settings--user interface--tracks).

Works great, thanks! I hope to give it a real workout this weekend.

I will add an option to change color/stroke to the TMG line in next version

Thank you very much!

A possible workaround is to run with offline maps and a custom map that does not cover the area you are navigating. This displays a light blue background which lets one clearly see their track and the TMG line. You can display a KML route to support basic navigation. Kind of drastic, but it works for me until I have something better.

I'm using OruxMaps version 6 and would like to change the color of the TMG line so that it shows up better on my custom maps (which have a lot of black). How do I change the color of the TMG line? Thanks!
