v2.5.0

v2.5.0

Upgrade notes

When using the v2_json marshaler (default), this version is fully compatible with previous versions of LoRa Server. When changing the marshaler to protobuf or json, you first need to upgrade to LoRa Server v2.1.0. When LoRa Server v2.1.0 is installed, it is recommended to use either the protobuf or json marshaler as it provides better compatibility (e.g. with the iBTS gateway).

Features

Protocol Buffer data serialization

To save on bandwith between the gateway and the MQTT broker (e.g. when the gateway uses a cellular connection), this update makes it possible to configure the marshaler for encoding / decoding the data (in lora-gateway-bridge.toml) using Protocol Buffers.

This will become the default option in LoRa Gateway Bridge v3.

New JSON format

The new JSON structure re-uses the messages defined for Protocol Buffers based serialization. For backwards compatibility, the default marshaler for LoRa Gateway Bridge v2.x will be v2_json.

Kerlink iBTS fine-timestamp

When using the protobuf or json marshaler, LoRa Gateway Bridge will expose the fine-timestamp fields when using Kerlink iBTS gateways.

Prometheus metrics

For monitoring the health and throughput of each LoRa Gateway Bridge instance, LoRa Gateway Bridge is able to expose various metrics that can be scraped by Prometheus.

Changes

Configuration structure of MQTT backend

The structure of the [backend.mqtt] configuration section has been updated. These changes are fully backwards compatible.

Improvements

All vendored dependencies have been updated.
