57 | Configure the Radio channel with the match radio settings frequency as the LoRa End Node | ||
58 | |||
59 | |||
60 | === 3.3.3 Configure TCP Server Info === | ||
61 | |||
62 | Note: Gateway may receive many LoRa packets, it will only transfer the packet with the same ID as specify in the channel. | ||

69 | === 3.3.4 About uplink data format from End Node === | ||
70 | |||
71 | The LoRa end node should upload the data with below format: | ||
72 | |||
73 | (% class="box" %) | ||
74 | ((( | ||
75 | Uplink Format:** (% style="color:#4f81bd" %)<Channel_ID>data(%%)** | ||
76 | For example, if we have configured 2 channels 12345 and 34567. | ||
77 | And there is are three LoRa End nodes sending: 12345,34567,78 | ||
78 | The LG02 will accept the data from 12345 and 34567, it will ignore the data from Node 78 | ||
79 | **Case 1**: | ||
80 | Node 12345 send <12345>field1=0.0&field2=1102.0 | ||
81 | Node 34567 doesn’t send anyting | ||
82 | The TCP/IP server will get {"12345":"field1=0.0&field2=1102.0"} | ||
83 | **Case 2**: | ||
84 | Node 12345 send <12345>field1=0.0&field2=1102.0 | ||
85 | Node 34567 send <34567>temp=34 | ||
86 | The TCP/IP server will get {"34567":"temp=34","12345":"field1=0.0&field2=1102.0"} | ||
