chirpstack-network-server

Features:

• Add configuration option to log all uplink / downlink frames into a database
  (--log-node-frames / LOG_NODE_FRAMES).

Bugfixes:

• Do not reset downlink frame-counter in case of relax frame-counter mode as
  this would also reset the downlink counter on a re-transmit.

Features:

• TTL of node-sessions in Redis is now configurable through
  --node-session-ttl / NODE_SESSION_TTL config flag.
  This makes it possible to configure the time after which a node-session
  expires after no activity (#100).
• Relax frame-counter mode has been changed to disable frame-counter check mode
  to deal with different devices (#133).

Features:

• Add --extra-frequencies / EXTRA_FREQUENCIES config option to configure
  additional channels (in case supported by the selected ISM band).
• Add --enable-uplink-channels / ENABLE_UPLINK_CHANNELS config option to
  configure the uplink channels active on the network.
• Make adaptive data-rate (ADR) available to every ISM band.

Bugfixes:

• Fix getting gateway stats when start timestamp is in an other timezone than
  end timestamp (eg. in case of Europe/Amsterdam when changing from CET to
  CEST).

Note: LoRa Server now requires a PostgreSQL (9.5+) database to persist the
gateway data. See getting started for more information.

Features:

• Gateway management and gateway stats:
  • API methods have been added to manage gateways (including GPS location).
  • GPS location of receiving gateways is added to uplink frames published
    to the application-server.
  • Gateway stats (rx / tx) are aggregated on intervals specified in
    --gw-stats-aggregation-intervals (make sure to set the correct
    --timezone!).
  • When --gw-create-on-stats is set, then gateways will be automatically
    created when receiving gateway stats.
• LoRa Server will retry to connect to the MQTT broker when it isn't available
  (yet) on startup, instead of failing.

Bugfixes:

• Fix error handling for creating a node-session that already exists
• Fix delete node-session regression introduced in 0.15.0

Features:

• Node-sessions are now stored by DevEUI. Before the node-sessions were stored
  by DevAddr. In case a single DevAddr is used by multiple nodes, the
  NwkSKey is used for retrieving the corresponding node-session.

Note: Data will be automatically migrated into the new format. As this process
is not reversible it is recommended to make a backup of the Redis database before
upgrading.

Bugfixes:

• Add mac-commands (if any) to LoRaWAN frame for Class-C transmissions.

Features:

• Class C support. When a node is configured as Class-C device, downlink data
  can be pushed to it using the NetworkServer.PushDataDown API method.

Changes:

• RU 864 - 869 band configuration has been updated (see #113)

Features:

• The following band configurations have been added:
  • AS 923
  • CN 779 - 787
  • EU 433
  • KR 920 - 923
  • RU 864 - 869
• Flags for repeater compatibility configuration and dwell-time limitation
  (400ms) have been added (see configuration)

Features:

• De-duplication delay can be configured with --deduplication-delay or
  DEDUPLICATION_DELAY environment variable (default 200ms)
• Get downlink data delay (delay between uplink delivery and getting the
  downlink data from the application server) can be configured with
  --get-downlink-data-delay or GET_DOWNLINK_DATA_DELAY environment variable

Bugfixes:

• Fix duplicated gateway MAC in application-server and network-controller API
  call

Bugfixes:

• Fix crash when node has ADR enabled, but it is disabled in LoRa Server

Features:

• Adaptive data-rate support. See features for information about
  ADR. Note:
  • LoRa App Server 0.2.0 or
    higher is required
  • ADR is currently only implemented for the EU 863-870 ISM band
  • This is an experimental feature

Fixes:

• Validate RX2 data-rate (this was causing a panic)

This release decouples the "inventory" part from LoRa Server and introduces LoRa App Server.
