Introduction

ChirpStack MQTT Forwarder is a MQTT packet forwarder for LoRa gateways. By default it forwards packets in Protobuf binary format, optionally it can be configured to use JSON encoding for debugging. In contrast to the ChirpStack Gateway Bridge, this component must always be installed on the gateway.
