The above topology indicates that Gateways G2 and G3 communicate with G1 via LAN/WAN.
WHat are components on the Gateways that are specifically involved?
Do I assume correctly that it is MQTT Broker on G1?
Are G2 and G3 have to run MQTT Clients or if they run MQTT Brokers as well the latter once will communicate the positioning data to MQTT Broker on G1?
So G1 MQTT Broker need to subscribe to G2 and G3 MQTT Topics?
Anyway, it would be great to read somewhere how all this interaction between Gateways works…
