Really Small Message Broker (RSMB) has support for MQTT-SN over UDP. Source is available from git on http://git.eclipse.org/c/mosquitto/org.eclipse.mosquitto.rsmb.git. To build it use MS Visual Studio and make from Cygwin.

trace_output protocol

# normal MQTT listener
listener 1884 INADDR_ANY

# MQTT-S outgoing multicast bridge (QoS -1)
connection Bridge_2_Mosquito
address mosquito_host_name:1883
# publish all messages
