MQTT data manipulation

[PaddyB]

Hi again ...

I wrote a quick python program to give me simulated data and send it over UDP to my openplotter RPI, the Pi receives the data at the selected port (nc -lu). But the data does not show up in SK diagnostic.

Sounds like maybe signalk hasn't a connection set to that udp port? 

I get
"pi@openplotter:~ $ nc -lu 55561

nc: Address already in use"  with signalk listening on that port .
