OpenCPN v3.0.2 and Raymarine SmartPilot X-5 Wheel integration problem

Hello

When I select Track my SmartPilot X-5 Wheel displays “NO DATA”.

The SmartPilot has successfully been calibrated.
The SmartPilot is connected to my OpenCPN 3.0.2 through the NMEA Interface on the back of the course computer.
OpenCPN is sending RMB and RMC sentences (verified with Portmon).
The SmartPilot controller correctly displays XTE, BTW, DTW, COG and SOG as sent by OpenCPN on the data pages.

Is there additional configuration that is needed on the SmartPilot?

Thanks in advance
Gordon

Hi Gordon

The SmartPilot also requires magnetic variation before going into track mode. If the RMC message does not contain a magnetic variation value, such as from a BU-353 gps receiver, no track mode is possible.

The next version of opencpn will provide a calculated mag variation if none is available from nmea input.

Hi Chuck

Thanks for the quick reply.

Any hope of a short term fix? Perhaps a hardcoded variation value that could be read from the .ini file and inserted into the RMC sentence.

Thanks again
Gordon

Any quick fix would involve you compiling your own OCPN version. So, that alternative is already open to you since both the code for the current stable version and the patch that implements getting variation from the WMM plugin are posted in our Github repository.

Consult the developer manual for more info
