Note that the integration events will contain the application +
device-profile + device tags. Integration events will NOT contain the
tenant tags. Most likely tenant tags will be used to store information
about the tenant, data that is unrelated to the integration events.
Fixes#211.
The gw_time defines the RX time by the gateway, the ns_time defines when
it was received by the NS. The latter could for example help to debug
latency between the GW <> NS.
The JSON encoding should only be used for debugging purposes! However
this change avoids showing errors in case there are unknown fields in the
JSON payload. This would happen when for example the MQTT Forwarder
and ChirpStack uses a different API version (which in case of Protobuf
would be fine, as long as the major version remains the same).
Historically, the tx power was defined as ERP. The Semtech UDP Packet
Forwarder protocol was never explicit if the "powe" field was in ERP or
EIRP. However, as the antenna gain in the Semtech UDP Packet Forwarder
is documented as dBi and is deducted from the "powe" field, this means
that "powe" is in EIRP.
This commit corrects all values to EIRP, to make sure that if the
antenna gain is properly configured (which should be), that the correct
rf_power is used by the gateway.
This implements end-to-end encryption between the end-device and
end-application. The encrypted AppSKey or SessionKeyID is forwarded to
the end-application which should be able to decrypt or request the
AppSKey to decrypt the uplink payload. As well the end-application will
be able to enqueue encrypted application payloads.
Using this mechanism, ChirpStack will never have access to the uplink
and downlink application-payloads.
This reduces the amount of dependencies in case not all features are
being used. E.g. tonic is only needed if using gRPC and pbjson,
pbjson-types and serde are only needed if using the JSON serialization.
This makes it possible to add gateways to a multicast-group, which in
case configured will always be used for transmitting the multicast
downlinks.
This also moves the multicast class-c scheduling to the multicast-group
configuration. Options are delay between multiple gateways, or GPS time
synchronized transmission.
The device might not always send its periodicity to the network-server
(using mac-commands). As well there is some ambiguity about the default
ping-slot data-rates. While the Regional Parameters Specification
defines the default beacon data-rates, it only defines the default
ping-slot frequency for Class-B.
This also changes the API field from class_b_ping_slot_period to
class_b_ping_slot_nb_k, where ..._k must be between 0 - 7 as defined by
the LoRaWAN Specification. This removes some ambiguity as 'period' could
mean different things in different contexts.
By selecting a region configuration, devices using the device-profile
will only stick to the selected region configuration, rather than the
configurations provided by the selected region common-name.
This change also renames the region 'name' option to 'id' in the region
configuration, as well it adds a 'description' to provide a human
readable description, which is used in the drop-down in the UI.
This also fixes the JS API generation. In a previous commit the the
protobuf package was updated, but the latest protobuf compiler no longer
supports generating JS code (this now requires an external plugin). This
has been fixed.
Please note that if you have implemented custom ADR algorithms that are
referring to the 'regionName' key, that you must change this to
'regionConfigId' (see the ADR code example).
This makes it possible for external services to subscribe (through
Redis) for realtime events. E.g. a create, update or delete device event
could trigger an external synchronization.
In case the decoded payload contains random keys the auto-detect
measurements feature will add new measurements for each uplink. With
this option it is possible to turn auto-detection off to avoid
polluting the database with many measurements.
Closes#42.
