ChirpStack Network Server v3.10.0
Multi-downlink commands and ACKs
With this feature, ChirpStack Network Server will send all downlink opportunities (e.g. RX1 and RX2) at once to the gateway, reducing the number of roundtrip in case of failures. Previously ChirpStack Network Server would send the next downlink opportunity on a received nACK. In case of a retry, this saves one roundtrip reducing the risk of a failed downlink due to network latency. The gateway will always send at most one downlink.
Note: This feature requires ChirpStack Gateway Bridge v3.9 or later, but is backwards compatible with previous versions, in which case ChirpStack Network Server will fallback into the old behavior. This backwards compatibility has some overhead, which can be controlled by the
multi_downlink_feature configuration variable.
This feature makes it possible to (temporarily) disable a device, in which case uplinks are ignored.
Join Server integration
The Join Server integration has been updated, so that it is no longer required to rely on DNS resolving of the Join Server. It is now possible to configure a per JoinEUI endpoint of the Join Server.
This removes the Geolocation Server integration (relying on LoRa Cloud) from ChirpStack Network Server. The reason for this is that there are various options for geolocation, some of them relying on the decrypted FRMPayload, e.g. in case of Wifi and GNSS sniffing. To provide one unified integration, this integration has been moved to ChirpStack Application Server.
Note: This will deprecate ChirpStack Geolocation Server as v3.11 will provide a per-application configurable LoRa Cloud integration.
This makes it possible to generate per-gateway client-certificates which can be used to implement gateway authentication and authorization. For example a MQTT broker can be configured to validate the client-certificate against a pre-configured CA certificate and if valid it can use the CommonName of the certificate (which contains the gateway ID) to authorize publish / subscribe to certain topics.
- Expose to Application Server if received uplink was confirmed or unconfirmed.
- Improve error handling and ignore uplink when uplink is received through unknown gateway.
- Avoid downlink mac-commands for ABP devices when factory frequencies have been correctly setup and are in sync with network channels.
- Support multiple Redis addresses for clustering. (#491)
This version improves the error handling when an uplink is received through an unknown gateway. Previously this was logged as an error, this has changed to a warning. Uplinks received through unknown gateways will be ignored. Make sure that all gateways in your network are configured in ChirpStack!
