	70	The LoRa end node should upload the data with below format:
	71
	72	{{{Uplink Format: <Channel_ID>data
	73	For example, if we have configured 2 channels 12345 and 34567.
	74	And there is are three LoRa End nodes sending: 12345,34567,78
	75	The LG02 will accept the data from 12345 and 34567, it will ignore the data from Node 78
	76	Case 1:
	77	Node 12345 send <12345>field1=0.0&field2=1102.0
	78	Node 34567 doesn’t send anyting
	79	The TCP/IP server will get {"12345":"field1=0.0&field2=1102.0"}
	80	Case 2:
	81	Node 12345 send <12345>field1=0.0&field2=1102.0
	82	Node 34567 send <34567>temp=34
	83	The TCP/IP server will get {"34567":"temp=34","12345":"field1=0.0&field2=1102.0"}
