Introduction

ChirpStack Concentratord is an open-source LoRa(WAN) concentrator daemon, part of the ChirpStack project. It exposes a ZeroMQ based API that can be used by one or multiple applications to interact with gateway hardware. By implementing and abstracting the the hardware specifics in a separate daemon and exposing this over a ZeroMQ based API, the packet forwarding application can be completely decoupled from the gateway hardware. It also allows for running multiple packet forwarding applications simultaniously.
