RAK7289V2 - 16 channels not usable in Basic Station mode

LPWAN Industrial Gateways / Concentrators
1

I’m currently trying to connect my RAK7289V2 Gateway (WisGateOS_2.2.11_RAK) to my ChirpStack LNS using Basic Station.
Unfortunately, I’m currently struggling with the configuration of the ChirpStack Gateway Bridge to use all 16 channels.

As soon as I configure an additional backend.basic_station.concentrators section, the RAK gateway refuses to work and logs the following error:
basicstation[10163]: [RAL:ERRO] Unsupported hwspec=sx1301/2

However, the device is definitely the 16-channel variant.
Is this a configuration error on my side or could this be a firmware bug?

My current ChirpStack Gateway Bridge configuration looks like this:

  # Region.
  region="EU868"

  # Minimal frequency (Hz).
  frequency_min=863000000

  # Maximum frequency (Hz).
  frequency_max=870000000

Did you ever figure this out? I am seeing the same thing with Basicstation but not with the packet forwarder. I can do 8 on any subband but once I go to 16 I get this error with basicstation.

I should say that I’m using the RAK7249 gateway but not on Chirpstack currently. The old semtech packet forwarder worked like a charm with Class B even. I’m hoping that there is something that I’m missing in the station.conf perhaps. :face_with_raised_eyebrow:

Hello,

So you are using RAK7249, is that correct?
This product is V1 and EOL, so no features will be added.

For the V2 gateway (like in the original post, RAK7289V2), we expect a fix for the 16ch BS mode soon.
