• On startup, validate that Gateway ID is 8-bytes. (#65)
• Update internal dependencies.

v4.3.1

Features

• Implement handling of ChirpStack Gateway Mesh heartbeat messages.

Improvements

• Update internal dependencies.

Bugfixes

• Spawn message-callback to not block MQTT eventloop. (#57)

v4.3.0

Features

v4.2.3

Improvements

v4.2.0

Features

paho-mqtt to rumqttc refactor

This refactors the code to use rumqttc instead of paho-mqtt as MQTT client library. As rumqttc is a pure-Rust MQTT client, which uses rustls for TLS, it is no longer needed to statically link against OpenSSL.

Improvements

• Add AMD64 build. (#46)
• Reconnect ZeroMQ REQ socket on error.
• Update dependencies.

Bugfixes

• Fix extending meta-data in Concentratord backend.
• Fix udp_bind > bind error in config examples. (#49)
• Fix corrupted payloads on mips / mipsel platforms. (#50, #52)

v4.1.3

Improvements

• Update RAK packaging for WisGateOS2 v2.2+.
• Implement preamble and no_crc fields.
• Update internal dependencies.

v4.1.2

Features

• Provide package for Multitech Conduit AP3.

Improvements

• Update internal dependencies.

v4.1.1

Improvements

• Add packaging for RAK ramips_24kec based gateways.
• Update internal dependencies.

Bugfixes

• Fix setting empty username and password in MQTT. (#257)

v4.1.0

Features

Improvements

DevAddr and JoinEUI filters

This adds a [backend.filters] configuration section under which it is possible to configure the prefix-filters for DevAddr (data uplink) and JoinEUIs (join-requests).

Time fallback

This adds a time_fallback_enabled configuration option to the semtech_udp section. If enabled and no RX time is provided by the packet-forwarder, then the ChirpStack MQTT Forwarder server-time will be used as fallback.

Build improvements

The provided pre-compiled binaries are fully static and based on musl libc. This removes the need to compile against a very old verion of glibc to stay compatible with old gateway firmwares.

Other improvements

• Update dependencies.

Bugfixes

• Fix bootstript for Dragino .ipk package.

v4.0.0

This marks the initial release of the ChirpStack MQTT Forwarder.

The ChirpStack MQTT Forwarder is a re-implementation of the ChirpStack Gateway Bridge for gateway installations only. The aim of this component is to provide a more lightweight solution, that also can be installed on gateways with a limited amount of memory (for example Dragino OpenWRT based gateways).
