61 === 3.3.3 Configure TCP Server Info ===
62
63 Note: Gateway may receive many LoRa packets, it will only transfer the packet with the same ID as specify in the channel.

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

121 Uplink Format: (% style="color:#4f81bd" %)**<Channel_ID>data**(%%)
122 And there is a LoRa End node sending below packets:

124 )))
125
126
127 (% class="box" %)
128 (((
129 LG01/LG02 will uplink 12345:Hello From Sensor1 and usr can use logread -f to check the log.
