69
70 The LoRa end node should upload the data with below format:
71
72 (% class="box" %)
73 (((
74 Uplink Format: <Channel_ID>data
75 For example, if we have configured 2 channels 12345 and 34567.
76 And there is are three LoRa End nodes sending: 12345,34567,78
77 The LG02 will accept the data from 12345 and 34567, it will ignore the data from Node 78
78 **Case 1**:
79 Node 12345 send <12345>field1=0.0&field2=1102.0
80 Node 34567 doesn’t send anyting
81 The TCP/IP server will get {"12345":"field1=0.0&field2=1102.0"}
82 **Case 2**:
83 Node 12345 send <12345>field1=0.0&field2=1102.0
84 Node 34567 send <34567>temp=34
85 The TCP/IP server will get {"34567":"temp=34","12345":"field1=0.0&field2=1102.0"}
