As written above, this is a bridging mechanism for any app not aware of the XGPS160. While using LapTimer, please disable it and let LapTimer access the XGPS160 directly. You can certainly use it but neither will LapTimer benefit from the direct integration nor can I say anything on the timing results.

In HLT/sensors I see motorola XT1049 GNSS (which is the phone).
Connected @ 10hz/9hz (alternating)
When I click on the BT icon HLT shows
Paired Bluetooth Devices:
XGPS160-3DED7E which is the Dual
I "think" HLT is seeing the DUAL "as if" it were the internal Motorola?
Do you agree?

Yes, that's exactly the effect from the bridging app. It shows up as internal GPS but feeds the XGPS160 into the location service (which in turn send 10 Hz). That's all fine except "You can certainly use it but neither will LapTimer benefit from the direct integration nor can I say anything on the timing results".

Under HLT gps/glonass sensors:
motorola xt1049 gnss
available
xgps160
connected
BUT the only way I got to this was to stop/start the helper app
The xgps160 shows 2 solid blue bars - two devices connected, after a few minutes (sitting on my desk) the xgps160 drops off and the motorola xt1049 gnss picks it up.
I think HLT sees the same device two ways, one as a mock location thru the android phone and the other direct?
Problem is the direct one is dropping after about 2 min. Any way to repair that?

In case it shows 2 blue LEDs, it has two connections. Most probably some other device you used for testing?

Nothing else at this time, just the phone & the Dual & HLT (and the internal gps of course).

Try scanning the environment using the Android Settings app / Scan Bluetooth... It is a question to Dual if one hardware can connect two times to the Dual. From my understanding that should not be possible. Even worse, in case it is possible, there are two services sitting on your smartphone accessing the external GPS. One is LapTimer. And the other?

I will ask Dual, could not find Android Settings app too many of them.
Thanks

From what I see is the Video behind acceleration - which in turn means you should increase the value by 0.5 or 1.0 seconds.
Overlay again afterwards to check the results.

I played a bit with the overlay sync settings respectively default setting, 0.5s, 0,0s:

0.0s looks the best. The GPS speed seems a little jerky to me. Why is that?
Btw. don't mind the car its a slow 120hp company car

Some short breakups in the GPS fixes, that must be it:
I think it might be the trees.
Another test, 0-120-0:
