Hi!

I have exactly same problem. If I’m using the NEMEA events, it keeps logging empty positions. Like this:

The point is, if I’m using the PositionReceived event, it never gets fired, since seems that the positions are not fixed on the module.

So, Seeed. We are having same problem.

Is there any solution for this? We need a replacement or even a refund for this modules if it don’t work.

Waiting to hear from you ASAP…
