Xiaoling 1.2 69
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"}
