73 (((
Xiaoling 6.3 74 Uplink Format:** (% style="color:#4f81bd" %)<Channel_ID>data(%%)**
Xiaoling 1.5 75 For example, if we have configured 2 channels 12345 and 34567.
Xiaoling 1.2 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
Xiaoling 1.5 78 **Case 1**:
Xiaoling 1.2 79 Node 12345 send <12345>field1=0.0&field2=1102.0
80 Node 34567 doesn’t send anyting
Xiaoling 1.5 81 The TCP/IP server will get {"12345":"field1=0.0&field2=1102.0"}
82 **Case 2**:
Xiaoling 1.2 83 Node 12345 send <12345>field1=0.0&field2=1102.0
84 Node 34567 send <34567>temp=34
Xiaoling 1.5 85 The TCP/IP server will get {"34567":"temp=34","12345":"field1=0.0&field2=1102.0"}
