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