Connecting Kerlink IFemtoCell to LoraServer gateway Bridge

Hello everyone,

I have a LoraServer deployed on an external server which is working well and connected to several gateways. I don’t want to take the risk to upgrade it to the last ChirpStack version because I’m afraid to loose data if there is any problem.

I have a new Kerlink IFemtoCell gateway, and I’m trying to connect it to this LoraServer. I installed on it a lora-gateway-bridge. My first question is : would it be possible to install a chirpstack gateway bridge and to connect it to the LoraServer ? Are they compatible ? If so, how should I do it ?

An additionnal issue is that I can’t run the lora-server-bridge. It worked once but now I have the error :
ERRO[0000] mqtt: connection error error="Network Error : dial tcp 5.83.233.149:8883: connect: connection refused"

I configured :

  • the gwmp section of the lorafwd.toml file to send datas to 127.0.0.1 on port 1700
  • the lora-gateway-bridge.toml to receive data on port 1700.
    I noticed that the adress in the lorafwd.toml changed twice I don’t understand why/how.
    Is there something wrong in this setting ? Did I forget something ?

The last point is about start the lora-gateway-bridge automatically. As it’s an old version, there is no documentation available anymore. I don’t know how to configure the gateway in order to launch the bridge when the gateway starts. How can I do that ?

Please let me know if you need any other information, thanks in advance for your help
