Hi
I wanted to ask this in the forum, but I couldn't find that anywhere.
I've built a simple GPS nodule by connecting an Adafruit Ultimate GPS to an Arduino MKR1000. That should connect over WiFi to a Raspberry Pi 3 running OpenPlotter 0.8.0.
So far, I have the Arduino connecting to the Pi 3 with the wifi access point started from the OpenPlotter configuration panel. There, it is also indicated that there is an MQTT broker that I might connect to, with the IP addresses indicated on the right. There is no information on what (if any) access credentials would be required.
However, trying to connect, nothing happens. I manually started a mosquitto broker via the terminal, and that works fine (so it looks like the port numbers for MQTT are not reserved by another process).
So is it true that the MQTT broker needs to be started manually, that there is no configuration preset for that? Secondly, do I need to subscribe to that same MQTT server via the "MQTT" tab on the OpenPlotter configuration panel, to get any SignalK messages to OpenPlotter?.
Cheers,
