First Commit of MQTT-SN Gateway
Add new SensorNetwork XBee Add a sensor network type in a start message. Update MQTTSNClient to avoid build warning. Update WiringPi's functions to my original ones. BugFix check msgId before adding waitdTopicId table. BugFix Process termination procedures Update print curent time in millseconds. update move currentDateTime() to linux directory. Bugfix: blink blue lightiIndicator. Bugfix: Register returns wrong id. change a status of the client to Disconnected. change client status procedure Update README BugFix: change Network Disconnect procedures.
