Factory-Preset Frequencies and Gateway-Profile

ChirpStack Application Server
1

Hey all,

I am currently trying on the settings of the application server and I have two questions:

  1. can someone tell me the correct values for the factory-preset frequencies in the EU-band?
    Is it 868100000, 868300000 and 868500000?
    I use a Nucleo-Board with an external Radio.

  2. When do I have to create a “gateway profile”?
    Should not every gateway be able to receive all channels between 867.1 MHz - 868.5 MHz?

Thanks and

Best regards

Does nobody have a tip, an idea or the solution?

This is for ABP only, in which case you could already provision the device with additional frequencies besides the default LoRaWAN channels.

  • When do I have to create a “gateway profile”?

It allows you to re-configure your gateways, if you’re not planning to use this leave it blank.

Thank you for your answer!

So I could provision the frequencies for the devices either via the GUI or in the firmware? That sounds great!

In which case, I would re-configure my gateway?

No, the list of frequencies must match the frequencies in the firmware of your device. The device-profile should contain the initial state of your device (when it turns on), not the desired state. The desired state is configured by the loraserver.toml configuration file.

In which case, I would re-configure my gateway?

Please see gateway re-configuration Gateway management - ChirpStack open-source LoRaWAN<sup>®</sup> Network Server.

Is it possible that it works despite inconsistent frequency lists? I have 8 channels configured in my firmware, but only the 3 default channels in the GUI. Nevertheless, I receive over all 8 channels. I ask because you said, that it must match.

Does anyone have an explanation for this?
