Features
Redis Cluster and Sentinel
This release introduces the support for Redis Cluster and Redis Sentinel.
Rejected uplink callback to Network Controller
A new API method has been added to the (optional) Network Controller called HandleRejectedUplinkFrameSet. When ChirpStack Network Server rejects an uplink (e.g. when the device is not known to the network, or the activation is missing), it will call this method (when the Network Controller is configured).
Improvements
- Change ISM band names to their common name. (#477)

Features
Downlink gateway randomization
When sending a downlink response, ChirpStack Network Server will select from the list of gateways with a given (configurable) margin, a random gateway for the downlink. This should result in a better downlink distribution across gateways. In case non of the gateways are within the configured margin, the best gateway is selected (old behavior).
Monitoring
The monitoring configuration has been updated so that it is possible to configure both a Prometheus endpoint at /metrics and healthcheck endpoint at /health. This change is backwards compatible, but to use the /health endpoint you must update your configuration.
Forward gateway metadata to AS
By forwarding gateway metadata to the (ChirpStack) Application Server, information like serial number, temperature, ... could be stored by the Application Server for various use-cases. The configuration of metadata is covered by the ChirpStack Gateway Bridge.
Improvements
Downlink LoRaWAN frame logging
Previously the first downlink scheduling attempt was logged (visible in the ChirpStack Application Server under the Gateway / Device LoRaWAN frames). This has been changed so that the scheduling attempt acknowledged by the gateway is logged. E.g. when RX1 fails, but RX2 succeeds this will log the RX2 attempt.
Bugfixes
- Update gRPC dependency to fix 'DNS name does not exist' error. (#426)
v3.7.0
v3.7.0
Features
Improve frame-counter validation
The refactored frame-counter validation makes it possible to report different types of errors to the Application Server which will make it easier to debug frame-counter related issues.
OTAA error event
OTAA related errors will now be pushed to the Application Server to make it easier to debug OTAA related issues.
Downlink tx acknowledgements
Downlink TX acknowledgements (by the gateway) are now forwarded to the Application Server. Please note that this is the TX acknowledgement by the gateway, indicating that it was enqueued for transmission.
Syslog output
When log_to_syslog is enabled in the configuration file, the log output will be written to syslog.
Improvements
- Implement setting max reconnect interval for MQTT gateway backend.
- Implement getting the device queue size only (instead of fetching the complete queue).
- Implement DNS round-robin load-balancing for gRPC.
- Cleanup old
apipackage (the API definitions have been moved to chirpstack-api). - Add uplink IDs to geolocation events for correlation.
- Remove legacy (and broken) device-session migration code.
- Cleanup (unused) gateway statistics code.
- Include 500KHz channels in US915 config examples. (#462)

v3.7.0-test.1
v3.6.0
v3.5.0
v3.5.0
Features
RX1 / RX2 selection logic
New configuration options have been added for RX1 / RX2 selection for downlink. (#429)
- Using
rx2_prefer_on_rx1_dr_ltit is possible to prefer RX2 for downlink, when the RX1 data-rate is less than the configured value. - Using
rx2_prefer_on_link_budgetit is possible to prefer RX2 for downlink when RX2 provides a better link budget than RX1.
Mac-command error handling
A new configuration option has been added to limit the number of mac-command errors (per device). This resolves the issue where the Network Server keeps trying to send a downlink mac-command to a malfunctioning device.
RPM packaging
This is the first release providing .rpm packages for CentOS and RedHat. (#454)
Improvements
Update lorawan package
The updated version contains logic for the EU868 band to either use 14 dBm or 27 dBm based on used frequency.
gRPC / Protobuf cleanup
All definitions are now imported from github.com/brocaar/chirpstack-api/go. When using the gRPC API, you must update your imports.
Environment variable configuration
Deprecate use of dots (.) in environment variable names, use double understore (__) instead. (#451)
Antenna diversity
Update lock key of MQTT gateway backend for handling of antenna diversity.
Internal improvements
The (re)usage of Redis connections has been improved.
