I've got a problem on my k750 with TB 0.9.79 and Oncourse BT GPS

The problem occurs when I'm walking slowly -- TB does not update my position for few minutes, then it updates for some moment and again few minutes I don't have updated info. As soon as I start moving fast (in a car) I get updated position (very strange).
I haven't verified if it's my GPS or TB, I'll have to test with another app, I haven't got much time for this, but I will.

here I upload nmea log, and hope that somebody (Kruch?) can check if the problem is in nmea already or it happens while parsing it.

here I have walked to directions that were not visible on TB at all. and if the problem is in nmea does it mean that my GPS is buggy or there could be some other reason with bluetooth connection (???), though I had the green light which shows that BT and GPS have working connection.

It's just making me nervous, this means that I can't use my GPS while walking in areas that I don't know.

again I hope some response
thanks in advance

I have tried with another app (GpsJ) and I had similar problem, so this means that the reason is my GPS (what the heck!!!)
has anyone experienced such a problem?
like GPS doesn't work correclty when speed is low (very strange)
what could be the reason?

also I've noticed, when a going car stops my GPS shows 0 speed only after 3-5 secs, is this a common thing, or again only happens with my GPS? Sad

Have a Look in 'Setings' -> 'Navigation' -> 'GPX ds (m)'
This is the minimum distance you have to have moved in Meters before a new Waypoint is saved.

Also Walking speed seems to be quite a problem for most GPS devices. Maybe it is the walking movement or the inacuracy simply shows stronger at slow paces.
