Hi!
How can you filter incoming PGNs from s NMEA2000/ Sealtalk ng network?
Especially I want to block PGN 130577.
The reason I need to do this, is that my Seatalk ng network sends different PGNs, with the same information.
e.g. SOG is send in PGN
129026 with the correct value
and in
130577 with a vaulty value
Both PGNs are mixed in the same signalK key and lets the SOG reading jump between right and faulty values.
It is the same for COG.
I tried with actisense NMEA reader. The PGNs can only be filtered within this App. The filter does not persist in OP.
As I understood, the filter list must be activated by OP with a command.
I also got a suggestion here in the forum to filter in node red, but in node red, the PGN data is already mixed to a signalK key.
I also checked the Raymarine network, no option to block sending PGNs.
Without the possibilitiy to block PGN 130577 I can’t use the CAN-USB converter.
Any ideas?
