I have pondered around the google trough and settled on trying the mosquitto broker. Mostly, because I have a Linux box that has it as a standard package. In the Opto22 videos, as far as I can tell, it is assumed that an MQTT broker is available.
I am setting up a development environment that will use multiple EPIC and RIO devices. We do need to use the “untrusted” ports and TLS with certificates. Certificates are another learning curve for me. In a nut shell I will have about 6 publishers and about 4 subscribers.
My understanding is I need to generate a certificate on each EPIC/RIO device and copy these over to the broker server and install them on the broker so that the broker can communicate via encrypted messages to/from each publisher/subscriber device.
Is this correct?
