Hello, I got the Mosquitto and paho-mqtt testing on my BBBW and BBGW. I can run a broker on each of them so far. I can also run some extra scripts in python to make them "almost work."
... Should I be using the BBGW/BBBW as a broker or should I use a larger computer as the broker? Seth P.S. I started to use this idea w/ websockets too.
