| 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: <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"} | ||
