[SOLVED] Raspberry 4 + moitessier hat / signalk -> opencpn: freeze

[luchin0]

OK, I think I have something.

If I cover the antenna with a metallic plate to force a signal lost then signal k data for position becomes:

{
 "longitude": null,
 "latitude": null
}

but OpenCPN is not managing this ok. The expected behavior is to keep the last know position before signal lost but currently opencpn is placing the boat in lat 0, lon 0 or any erratic position.

Is this the issue all of you are experimenting?

In my case the position jump every second till when there's an input like 4333256 2233355 (or number like that) and at this point opencpn freeze.
