v4.13.0

Features

Refactor Mesh heartbeat

This refactors the Gateway Mesh heartbeat payload into a more generic Mesh Event payload, which can be used by both “known” and “proprietary” event types. The first implemented “known” type is the heartbeat. While this refactor is not backwards compatible and requires ChirpStack MQTT Forwarder v4.4+, the backwards incompatibility does not affect the functioning of the Gateway Mesh itself.

Improvements

  • Store mac-command stats in device-session (instead of Redis key).
  • Update scheduler_run_after directly at devicve-session get (avoiding race-conditions between Class-A & Class-B & -C).
  • Rename m_type to f_type to align with LoRaWAN 1.0.4 specification naming.
  • Make it more clear if FUOTA job is running or if it is schedule.
  • Make AMQP integration exchange configurable. (#677)
  • Replace Redis GETDEL by pipelined GET and DEL commands. (#682)
  • Sort NULL values as smallest value (device and gateway last-seen sorting). (#683)

Bugfixes

  • Fix custom root CA certificates not taken into account. (#684)
  • Fix inconsistency in Class-B periodicity between backend and UI and align naming with LoRaWAN 1.0.4 specification naming. (#670)
