According to the MQTT-SN spec, if a client goes to sleep by sending DISCONNECT with a timeout, and it reconnects within that period, the broker should remember all the registered topics for that client so it doesn't have to re-register. Mosquitto/RSMB doesn't do that as can be seen in MQTTSProtocol.c:442

Yes. Sleeping clients is one of the two functions not yet implemented. The other being the ability to pre-register topics. I'll leave this bug open pending the addition of the function to support sleeping clients.
