Configuration

ChirpStack Concentratord provides different binaries in order to target different hardware platforms.

ChirpStack Concentratord makes it possible to use multiple configuration files, by repeating the -c argument. For example:

  • concentratord.toml for generic configuration
  • region.toml for region specific settings (e.g. Class-B beacon configuration)
  • channels.toml to configure the channels

When using ChirpStack Concentratord within a region supporting multiple sub-bands, this means that only the channels.toml file needs to be updated when changing the sub-band, avoiding duplication.

chirpstack-concentratord-sx1301

The chirpstack-concentratord-sx1301 binary has the following command-line flags:

concentratord 4.3.5
Orne Brocaar <info@brocaar.com>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -c, --config <FILE>...    Path to configuration file

SUBCOMMANDS:
    configfile    Print the configuration template
    help          Prints this message or the help of the given subcommand(s)
