My IoT node based on SX1276 is sending the Join Request to my Gateway based on SX1301 and SX1257 (RAK2245 board). I see the Class A IoT node spitting the message saying that it is sending the Join request. However I am not seeing the Join request at the concentrator. Is there some special debug I need to enable to see the packets received by the concentrator?
Which LoRa Server are you using? Is it loraserver.io or other LoRa Server?
If your own LoRa Server is loraserver.io, you can have a look at the document which @Hobo has mentioned. In that document, the 6.2.2 section has introduced how to configure your LoRa Gateway to connect with a loraserver.
In the picture 3, you should fill it with your own LoRa Server’s IP address.
If your own LoRa Server is other LoRa Server, you can do as follow:
Choose the item 3 to open the configuration file, then you can see some contents as follow:
I have run a radio calibration test provided by libloragw library. Below is the output. Something seems to be wrong in my RF settings. Can someone help …

Below is calibration log which report problem with radio A for image rejection and radio B for TX imbalance.
Can RAK experts comment on this? Is my concentrator bad?

Hi @sgodey
What are you using, Basic Station or RAK “station” .
Please download and install RAK software for RAK2245 from here RAK Git . Or download SD image from here RAK2245 SD.
And make the same tests.
