I have gone thro hell and back again trying to get Ocpn/o plotter and pypilot to come together...literally lost weeks trying everything I could find on you tube video's the docs section etc. They all basically say different ways. and none sort of brings it all together. Also the programs have been updated and the documentation and on- line stuff is frequently no longer valid.....very very fraustrating. The end result for me using a gps usb puck antena was actually the simplest howevr to get there was horrible. For another type antenna you may have to do something different but the jist should be the same.
Basically, there are a whole bunch of protocols and setups that can get data into the end user, however what I wanted is to get the verification that good data gets into ocpn and into pypilot. This verification is the yellow bars that show the connections made in signal K and match your device name etc, and importantly that the bebugger in ocpn shows a continuous nmea stream. In some setups this doesl not show at all ( setup via signal k for instance) and the messages column is misleading if you dont look carefully to see that the time stamp is actually posting. And finally the big ticket is that the little boat in ocpn goes red and the top rightbox shows Gps strength bars. .
The following is the only way I found:
Serial 2.2.3 invoke devices - shows usb port give alias and device = ttyusb0 . Device should be found automatically and shows as manu name etc.
check nmea 0183
Apply..... line goes green to confirm
Click line and add to GPSD baud = auto
Valiidate:
pull plug and line goes red indicating it is disconnected - replug = green
Next = OpenCpn 5.6.2:
options - go to connections box :
"add connection"
device should show with your alias automatically - if not go back and check everything previous
network input GPSD address ...should default to 0.0.0.0 port 2947 priority 1
...these should load by default so leave everything as is
add user comment - this is an ID for the connection
Apply
Ocpn should now completes the process via signal k automatically
Overview:
no signal k screwabout needed - just serial and ocpn
Use GPSD option. This is a protocol/system that is used in most cell phones etc.
End Result:
red boat
gps bars
debugger shows 0183 stream
yellow bars in signal k
