The VBOX Sport exhibits the same behavior as the QStarz- consistently reads "Not available". I went ahead and reinstalled SoloStorm and it was able to properly connect to either device. There appears to be something wrong with HLT's connection to BT on the Samsung Galazy Tab 4.

I really work hard to find reasons for whatever configuration my valued customers run, but I start to run out of ideas. ;-) Maybe anyone else with a Galaxy Tab 4 can jump in. Sorry to repeat, but it is most probably some configuration / conflict or general BT stack issue for the Galaxy Tab 4. Pleas...

The persistent problem is it either shows "Not available" in the Sensor List or "Connected @ 5 Hz" but 0Hz in the GPS view when the screen is not locked. The issue is about the same whether SoloStorm is installed or not. Losing GPS after a screen lock is a problem, but if I can't...

SS has now been entirely removed from the system to aid troubleshooting. For nearly 10 minutes, launching, closing, backgrounding and foregrounding, HLT was reading "Not available" on the QStarz. Randomly, I check and it is showing "Connected @ 5 Hz". Screen goes into power savin...

It has to be a conflict between the two softwares. I have been able to get it work through this sequence of events: Switch SS to Internal GPS and turn Logging on. Launch HLT and go in Sensor List. If "Not available", go back to SS, go back to HLT and check again. If still "Not availab...

You may recheck the basics: unpair the device, make sure no other device is accessing the Qstarz, remove the sensor entry in LapTimer, reboot the smartphone. Remove / kill any other app accessing It (helpers in particular). Harry Already did that multiple times. I have a vanilla install of a Samsun...

And what about a failure to actually connect to the Qstarz within HLT? HLT is never going to the background, never crashing.

I have one log from my prior track day that showed 10Hz data, all the others were 1Hz. I cannot be 100% sure, but I don't think I could achieve 10Hz with anything but the QStarz.

The Insecure connection did not help.

I used SS on my 818XT yesterday without issue. I rebooted the device and launched HLT to continue troubleshooting- it would not connect to the 818XT at all! There are no running apps, no GPS Helpers, and HLT always shows "Not Available" for the 818XT. Removing and re-adding doesn't change ...

This is a vanilla Samsung OS. The only items installed are SoloStorm and Harry's Laptimer; no GPS helpers unless Samsung installed them.
