Rak831 with Gateway OS concentratord failing

ChirpStack Gateway OS
1

Hi,
I am pretty new to the ChirpStack server and I thought the easiest way to get started would be plugging in the rak831 and install the full image, but I see the following errors:

The concentratord keeps trying to Initializing. Should it be supported out of the box? Is there any manual I can follow to configure the full ChirpStack (using the OS provided, not Raspbian + packages) with Rak831.

I am using the following board to connect it to a Pi v3

Thanks.

it would be better if you posted the concentrator configuration file.
I had an error like this when I was using the wrong configuration.

as I understand it the files should look something like this

Concentratord configuration.

Hi,
It turned that I needed to reset the GW and it just started working. Now I am debuging why I can’t receive data from the node to the GW, but that is another story

Thanks.
