70 Note: Gateway may receive many LoRa packets, it will only transfer the packet with the same ID as specify in the channel.

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

136 LG01/LG02 will uplink 12345:Hello From Sensor1 and usr can use logread -f to check the log.
