Re: "Gap" in GPS fixes with Racebox Mini
That’s probably the noise one needs to expect from a sensor not filtering data a lot. Consumer level GPSes (like those in smartphones) are heavily filtered / smoothed to show “nice” data. Devices like VBOX sport (and probably Racebox) do almost no filtering / smoothing but deliver raw data. Instead ...

Re: "Gap" in GPS fixes with Racebox Mini
In case it is 0.5 to 1s, this is a bandwidth problem. They may occur in case you have BT devices around adverting. You can look for nearby BT devices by using apps like LightBlue. In case the gap is bigger and LapTimer is falling back to the internal sensor (1 Hz rate for at least 3 or 4 seconds), t...

Re: Kiwi 3 OBD Refresh Issue with BMW
Mfi is basically Bluetooth SPP with some overhead. But I really can't answer this. I know that an OBD adapter running at 8 Hz plus a 20 Hz GPS device usually play together on track. In the pits it might bot because you have so many devices around.

Re: Kiwi 3 OBD Refresh Issue with BMW
Bandwidth used for GPS multiplies with update rate. A device with 25 Hz will use a lot of bandwidth. OBD will get slower when bandwidth is low. Can't say for the GoPro.

Re: Kiwi 3 OBD Refresh Issue with BMW
Bluetooth devices can “advertise” their services, usually after setting them to be ready for pairing or (for BT LE), simply broadcasting availability of services. Both operations reduce the bandwidth available, the former considerable. I recall I have seen in car stereos advertising constantly and c...

Re: GoPro 10 supported?
Any external action cam will require you to transfer footage to your smartphone. The benefit from integration (opposed to simply adding any external video) is that LapTimer triggers the cam in sync with sessions driven.

Re: Selected verify data, app crashed and now won't reopen
Hello, The upgrade is not related to the crash. This is most probably a database problem Verify Data revealed. To get the app up and running again, the current (corrupted) database needs to be inactivated. The procedure to do this is described here: http://forum.gps-laptimer.de/viewtopic.php?t=6176 ...

Re: Kiwi 3 OBD Refresh Issue with BMW
OBDLink CX or MX+. But I doubt it is a problem with LapTimer and the Kiwi 3. Try without Racebox please, it may use up all bandwidth.

Re: Data is out of sync with video
Yes, future recordings only.
With reference lap I meant one which can serve as a typical example of laps you record.

Re: GLP Unexpected Timer Stop
The timer is 3 minutes. A "stand still" is defined as a speed below 1.5 km/h. Both values are hard coded currently.
