	74	(((
6.3	75	Uplink Format: (% style="color:#4f81bd" %)<Channel_ID>data(%%)
1.5	76	For example, if we have configured 2 channels 12345 and 34567.
1.2	77	And there is are three LoRa End nodes sending: 12345,34567,78
	78	The LG02 will accept the data from 12345 and 34567, it will ignore the data from Node 78
1.5	79	Case 1:
1.2	80	Node 12345 send <12345>field1=0.0&field2=1102.0
	81	Node 34567 doesn’t send anyting
1.5	82	The TCP/IP server will get {"12345":"field1=0.0&field2=1102.0"}
	83	Case 2:
1.2	84	Node 12345 send <12345>field1=0.0&field2=1102.0
	85	Node 34567 send <34567>temp=34
1.5	86	The TCP/IP server will get {"34567":"temp=34","12345":"field1=0.0&field2=1102.0"}
