Tech Log #023: AR Marker MQTT messages
AR markers triggering messages to send to the alternate (secure) MQTT server is working. The preliminary topic structure was chosen, which gives each marker type its own topic, and sends the state when it enters the view, still in the view, and exits the view. Next step is to make sure the device can receive these messages, and have the device send its sensor data – only when the marker is in view (as to not overload this MQTT server (since it isn’t running on our AWS)). As well, next step is sending a marker state heartbeat when it is in view.
