RAK7289: "Unsupported hwspec=sx1301/0" when attempting BasicsStation operation

LPWAN Industrial Gateways / Concentrators
1

I’ve successfully operated a new RAK7289 as a Network Server (very slick!) but now I’m attempting to configure the RAK7289 for Basics Station to a local ChirpStack server, but I see no connections from the RAK7289 to ChirpStack, and find these errors in system log:

Sat Jun 25 01:19:02 2022 user.err basicstation[24773]: [RAL:ERRO] Unsupported hwspec=sx1301/0
Sat Jun 25 01:19:02 2022 user.err basicstation[24773]: [any:ERRO] Closing connection to muxs - error in s2e_onMsg

IIRC, the 7289 uses SX1303s, so this error message seems wrong.

Also fishing around the filesystem on the 7289, I find the following, which may not be correct:

root@RAK7289:/usr/share/lora# grep 1301 *

Any pointers?

Here’s more error messages from the RAK7289:

I’m using ChirpStack on the server, which seems to be listening at port 3001 as expected, and connections occur. Is there some additional configuration I need to do on the server side?

Thanks -

Now I understand: I needed to configure the channels for the SX130x in the ChirpStack gateway configuration.

  [[backend.basic_station.concentrators]]
    [backend.basic_station.concentrators.multi_sf]
    # SB1
    frequencies=[
      902300000,
      902500000,
      902700000,
      902900000,
      903100000,
      903300000,
      903500000,
      903700000,
    ]

    [backend.basic_station.concentrators.lora_std]
    frequency=903000000
    bandwidth=500000
    spreading_factor=8

Once I configured for 8 + 1 channels, I have a working GW using Basics Station.
hwspec = sx1301/1, meaning 1 SX1301

So then I add a second concentrator definition and now ChirpStack has hwspec=sx1301/2:

  [[backend.basic_station.concentrators]]
    [backend.basic_station.concentrators.multi_sf]
    # SB1
    frequencies=[
      902300000,
      902500000,
      902700000,
      902900000,
      903100000,
      903300000,
      903500000,
      903700000,
    ]

    [backend.basic_station.concentrators.lora_std]
    frequency=903000000
    bandwidth=500000
    spreading_factor=8

  [[backend.basic_station.concentrators]]
    [backend.basic_station.concentrators.multi_sf]
    frequencies=[
      903900000,
      904100000,
      904300000,
      904500000,
      904700000,
      904900000,
      905100000,
      905300000,
    ]

    [backend.basic_station.concentrators.lora_std]
    frequency=904600000
    bandwidth=500000
    spreading_factor=8

Any suggestions how to configure this on ChirpStack so the RAK7289 will use Basics Station for 16 channels?
