How to forward IMU data to signalk/opencpn?

[volksbar]

Hello,

Do you know how to send the PyPilot data to signal/OpenCPN (e.g. compass heading, rudder, accelerometer)?

Some background information on where I am heading:
 
I am trying to setup the radar overlay in the radar_pi plugin of OpenCPN (using Navico Halo 20). It requires both the GPS and the compass heading as NMEA0138. (see the pic below).

   

The compass heading data comes from PyPilot but currently no data/measures that PyPilot collects is passed on to SignalK/OpenCPN. 

Any hints or suggestions are highly appreciated! Many thanks!

What do you mean the compass heading comes from pypilot but is not in opencpn??

There is more than one way to pass the data, typically

1. nmea0183    You can either use the pypilot plugin in opencpn which should auto-negotiate this if the option is checked in the plugin,  or else, make a nmea connection in opencpn on port 20220 to pypilot
   
2. signalk   You may need to grant pypilot read/write access in the signalk web configuration and create a signalk connection in opencpn
