Send Custom NMEA2000 data

[JBO]

Hello,

Im currently writing my bachelor thesis about ways to sucessfully send NMEA2000 Format Messenges into an existing NMEA2000-network.
The endgoal is enabling control of the boads rudder with a simple Joystick. For this purpose im searching for an program, which is capable of sending custom NMEA2000 messages into the network. Im currently using a Raspberry PI 4 with openplotter installed and the NGT-1. To this point I have tried Canboat, which sends me back an EOF-Error whenever I try sending using the following code:

Code:

echo 2012-06-17-15:02:11.000,6,59904,0,255,3,14,f0,01 | actisense-serial /dev/ttyUSB0

In detail it starts reading the bus datastream for a few messages before giving me that error.
Every help and tips would be much appreciated,
best regards,
Jannis

you may want to take a look at the code of the signalK to NMEA2000 plugin for signalk and see if you can gain anything from that:
