LapTimer v19 announcement (iOS and Android)

[Harry]

I like the new accelerometer calibration. The internal camera setting worked like a charm. You might have a little too much yaw in the LHT and RHT presets, though. It looked like about 45 degrees. Using a forced calibration on the individual setting solved that problem, but a straight ahead portrait preset like the internal camera straight ahead landscape preset would be nice.

There are actually two transformations applied: 1) device rotation (rotate whatever portrait / landscape the user selects to one "standard internal" orientation) and 2) yaw/tilt/roll transformation - which is either a preset, or individual, or individual locked. So the presets do not work on different device orientations but after 1) has been applied. This makes the whole process a lot easier to understand when coding this stuff.

For the actual angles used for tilt and yaw, please check illustration #4 in LapTimer's new Quick Reference. It animates through RHT, LHT, video and motorbike presets. Like any "one size fits all" approach, the presets are finally always wrong. But they will be better than an individual calibration being off by accident... For advanced users with a fixed mount, a locked individual calibration is the best approach.

Hi Harry,

I just upgraded Petrol Head Edition on my Android to Grand Prix edition, seemed to upgrade OK and payment was fine, but the installed version still reflects the Petrol Head Edition... is this expected or should it have updated to the Grand Prix edition reflected this in the version description ?

Keep up the good work..

Steve

The info screen should give you GrandPrix. In case it doesn't, just repeat the upgrade from Add-ons. You will not be charged twice.

Thanks Harry, all sorted....

Hi Harry - update looks great.

Did the feature to only use an external cam (e.g. Hero 4) without the onboard video make it into this release? I've had a good dig through the settings but can't see it.

[Harry]

No, has been shifted to the next feature release.

Just playing about with the HR support, I've enabled it in the fitness on iOS to share with HLT - should it show in the sensors? It's a Wahoo TICKR. I restarted the app after connecting the HRM.

HR information is actually not yet treated as a "sensor". Instead, LapTimer accesses the data stored in Health app - just like a database. So if your sensor delivers HR to Heath app, it will be available in LapTimer automatically. You can see it in the Laps chart and it has its own page in Charts too. NB: supported in LapTimer GP only-so if you run Petrolhead, please upgrade in LapTimer ‣ Administration ‣ Add-ons ‣ GrandPrix Upgrade.

Thanks Harry - so the info is only available when looking at the data post lapping, nothing to worry about that I can't see anything now when setting up?

I've always been on the GP Version

Exactly, no real time information, just during analysis.
