LG02 LoRa Gateway User Manual

Step3: Configure TCP Server Info
Note: Gateway may receive many LoRa packets, it will only transfer the packet with the same ID as specify in the
channel.
Step4: About uplink data format
The LoRa end node should upload the data with below format:
Uplink Format: <Channel_ID>data
For example, if we have configured 2 channels 12345 and 34567.
And there is are three LoRa End nodes sending: 12345,34567,78
The LG02 will accept the data from 12345 and 34567, it will ignore the data from Node 78
Case 1:
Node 12345 send <12345>field1=0.0&field2=1102.0
Node 34567 doesn’t send anyting
The TCP/IP server will get {"12345":"field1=0.0&field2=1102.0"}
Case 2:
Node 12345 send <12345>field1=0.0&field2=1102.0
Node 34567 send <34567>temp=34
The TCP/IP server will get {“34567”:”temp=34”,"12345":"field1=0.0&field2=1102.0"}
