LG02 LoRa Gateway User Manual

23 / 63

Check Result

After above settings, the LG02 should be able to connect to TTN, below is the result seen from

TTN:

4.2.2

Configure LG02’s RX frequency

Now we should configure LG02 to act receive the LoRaWAN packets. This is in Channel 1, we

configure is to use 868.1Mhz (868100000 Hz) as below.

Users only need to configure the RX Radio settings. In LoRaWAN protocol, the downlink packet

from LoRaWAN server will specify the downlink frequency and SF (Spreading Factor), the gateway

will use these parameters to send out Downlink LoRaWAN packets.
