> A feature of MQTT-SN is the QoS -1 publish, which does not require an MQTT connection to the server.  The publish packet is sent to a multicast or broadcast address, to use UDP as an example, and the server could be listening on that address.  Obviously, there are no guarantees that any server will receive the message.
