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

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

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