GPS catching in "Pause" mode

KAC

Hi, aol.
I did not find option when racechrono could open GPS port but dont start session.
As I understood it only opens GPS port meaning catching sattelites when I start new session or resume old one.
I thing it is not good.
It would be nice to make possible catching GPS in "Pause" mode. Nobody wants to add points into track with bad DOP.

What is the use case for this, are you using RaceChrono for mapping or land surveying? For motor racing the these low quality points do not matter much at start-up. And you're going to get them anyways when going hard at corners etc.

Example:
I come to kartodrom to drive 10 laps on kart (about 10 minutes). But I know that before I need to "warm up" my GPS system at least for 10-15 minutes for good quality.

OK. I will think of something like this for the next version. A screen to monitor the GPS quality before actually starting recording.

I think that it would be better if racechrono should catch GPS signal always!
And save track only when you press resume session.

Of course I find solution for my situation.
I use GPSgate to catch GPS and redirect data to another serial port.
I start racechrono exactle before my race on kart. So racechrono gets very good signal immediatly.

But you know that gpsgate is not freeware, so I need to use crack version)

I remember early versions of RC were always connected to the GPS, but I changed that because Bluetooth drains the phone battery quite quickly. But yes I see that there is a problem. You could also keep the session running, but of course you'd get some useless plots.

There is also feature request about not logging plots when stopped, I think that would be good solution to your problem too. So you wouldn't need to pause/resume if you don't want to.

KAC

You are right!
Stop logging when speed equal 0. more then 5-10 points!

I can start the session and get GPS link within 10 - 15 seconds. I then lock the keypad on the phone and ride my session on the motorcycle.
When I am done I unlock the keypad and pause the session, none of the sessions take up that much space on the data card

I had this concern also. My solution is to start/resume session while in pre-grid. I just let the timer roll for a few minutes prior to start. Once I cross start/finish the useful lap timing begins. I then just ignore the first grid/lap info.
