	82	(((
6.3	83	Uplink Format: (% style="color:#4f81bd" %)<Channel_ID>data(%%)
1.5	84	For example, if we have configured 2 channels 12345 and 34567.
1.2	85	And there is are three LoRa End nodes sending: 12345,34567,78
	86	The LG02 will accept the data from 12345 and 34567, it will ignore the data from Node 78
1.5	87	Case 1:
1.2	88	Node 12345 send <12345>field1=0.0&field2=1102.0
	89	Node 34567 doesn’t send anyting
1.5	90	The TCP/IP server will get {"12345":"field1=0.0&field2=1102.0"}
	91	Case 2:
1.2	92	Node 12345 send <12345>field1=0.0&field2=1102.0
	93	Node 34567 send <34567>temp=34
1.5	94	The TCP/IP server will get {"34567":"temp=34","12345":"field1=0.0&field2=1102.0"}
