Hi Leif, those are most probably some measurements that could be or should be filtered out.
But they are not; and we are working on a better solution (sending PGNs out from Venus OS); so not fixing issues like this anymore in that cable.
What you should do is make sure that all firmware is uptodate: I have not heard this complaint before; so with a bit of luck its fixed somewhere.
But then again; you’ve already done that before reaching out; right? ;o)
