ChirpStack Gateway Bridge is a service which converts LoRa® Packet Forwarder protocols into a ChirpStack Network Server common data-format (JSON and Protobuf). This component is part of the ChirpStack open-source LoRaWAN® Network Server stack.

You will find additional information about the Bridge directly on the official ChirpStack documentation

The Bridge can run either on the gateway directly or on the infrastructure server side. The LORIX One is shipped with the Bridge.

Available backends

The Bridge back-end is a Packet Forwarder running on the gateway. The Bridge is compatible with two Bridges:

  • Semtech Packet Forwarder
  • Basic Station Packet Forwarder

On the LORIX One, the Bridge is used in combination with the UDP Packet Forwarder, who is based on the Semtech Packet Forwarder.
