Changelog
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.
