Xiaoling 1.5 70 (% class="box" %)
71 (((
72 Uplink Format: <Channel_ID>data
73 For example, if we have configured 2 channels 12345 and 34567.
Xiaoling 1.2 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
Xiaoling 1.5 76 **Case 1**:
Xiaoling 1.2 77 Node 12345 send <12345>field1=0.0&field2=1102.0
78 Node 34567 doesn’t send anyting
Xiaoling 1.5 79 The TCP/IP server will get {"12345":"field1=0.0&field2=1102.0"}
80 **Case 2**:
Xiaoling 1.2 81 Node 12345 send <12345>field1=0.0&field2=1102.0
82 Node 34567 send <34567>temp=34
Xiaoling 1.5 83 The TCP/IP server will get {"34567":"temp=34","12345":"field1=0.0&field2=1102.0"}
