Kerlink iFemtocell TTI Stack registration issue

Hello everybody!

I bought a Kerlink Wirnet iFemtocell Gateway 868 MHz and I’m trying to register it on the The Things Industries Stack, but I am unable to do it.
All the instructions I found from the manufacturer, as well as on the TTN site, are out of date. The instructions are written for iFemtocell firmware version 4.3.3 or 5.11 (https://wikikerlink.fr/wirnet-productline/doku.php?id=wiki:lora:basic_station_forwarder#ttn_lns_configuration_tool). Today, the current firmware version is 6 (KerOS 6). So the first thing I did upon purchase was to update the gateway to the latest version.
Likewise, TTN documentation only exists for The Things Network V2, which is no longer maintained. (https://www.thethingsnetwork.org/docs/gateways/kerlink/keros/). Today the current stack is V3.

There is manufacturer documentation on how to register a gateway to TTI on firmware version 6 (https://keros.docs.kerlink.com/en/lora/use-cases). But that documentation also uses the same 2 commands as for version 4.3.3
and they are:

  1. klk_ttn_config -u https://tenant.eu1.cloud.thethings.industries -t NNSXS.R6D3ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHI.ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIABCDEFGHIJKLMNOPQ -f EU_863_870
  2. klk_bs_config --enable

I added the gateway to the TTI Stack GUI (Web page) and created API keys for it. Now I’m trying to register it on TTI using LoRaWAN Basic Stations protocol, but every time I type the above two commands, I get the following error:

Adapting base URL for Cloud Addressing to https://tenant.eu1.cloud.thethings.industries
could not retrieve user of organization id

  • Of course, “tenant” in my case is my actual tenant, so the URL is slightly different, but the error is the same.

Unfortunately, the TTN documentation for the V3 stack does not contain the iFemtocell gateway, but only the iStation (https://www.thethingsindustries.com/docs/gateways/models/kerlinkwirnetistation/) and I cannot use the same instructions.

Has anyone managed to register an iFemtocell on Stack V3 using KerOS6 firmware?
