Hi guys, I got an error while configuring RAK5205 to LoraServer. The command is at+join. Any help will be appreciated

Is device EUI and App EUI same?

hello！
We need to gradually find out what the problem is,
First you need to check that your loraserver is working properly on other nodes
Then you need to check that the three parameters you configured are the same as those on loraserver.
Did you follow the 6 chapters in the document?
6. How to connect with LoRaServer?

In the loraserver of raspberry pie, APP_EUI is configured arbitrarily, as long as it is properly formatted and does not affect the connection.
What version number is your RAK5205 using? Check it out with the command: at+version
When you send data, will you receive any response data in the gateway?

5

I am using 3.0.0.3.H version. But as per the above pictures is it configured correctly? .

6

Yes, your configuration is correct.
Can you tell me what frequency band your gateway and nodes are using? EU868, US915…

7

Gateway is configured with AU915

8

So you use the command

at+get_config=lora:channel

to check your configuration and send me the screenshot. Thank you

10

When you connect to the gateway and send the data, does it receive anything?

It is only loading, nothing happens

You need to join with RAK5205 and make sure your devices are equipped with antennas

13

The antennas are attached

Do I need to check this box?

15

at+get_config=lora:status

at+get_config=device:status
You try sending these two commands and see what response he gets.

You try to restart the gateway and wait a minute to restart the node again.

Edit: got it working by changing to EU868 at+set_config=lora:region:EU868 and back to AU915 at+set_config=lora:region:AU915 :unamused:

Hi,
I have the same issue, the 5205 does not want to connect to my chirpstack (loraserver), I have other nodes (LoPy4) joining the server.

I don’t see anything in the logs of the packet forwarder when sending a at+join command. it’s almost like its not transmitting?

>>at+get_config=lora:status
OK.

Can you tell me what gateway you are using?

Hey @Nicholas,
I’m using a DYI gateway with a rak2247 concentrator and running chripstack.

The gateway hardware EU868 of RAK2247 is different from that of US915. If you use the same hardware without switching, I guess this is the problem.
