Customer Issues Solved
Issue Description ID
Bug with rules engine/Resource Collection. Adding a Location to a Resource Collection incorrectly listed Devices of child Locations. DDM-16213
GUI improvement needed – Resource Collection. Choosing Location can be difficult if you have several Locations with the same or similar name. Added parent Location in parentheses in the Resource Collection window to make it easier to differentiate Locations with similar names. DDM-16215
Filter in endpoint /events is not working correctly. Whenever the filter contained the ”active” key, the response listed all active events, regardless of whether the key value was set to ”true” or ”false”. This has been changed to correctly select events based on the key value in the request. DDM-16378
SynchronizeAllResourceCollections causes CPU spikes and queue buildups. Improved performance of the synchronize Resource Collections job. DDM-51588
When importing a Device Type, Setting Category is not imported. Export of Device Type included Setting Categories, but import did not handle Setting Categories. DDM-87346
Wrong write command sent after registration. Fixed an issue where a Resource could be linked to a template belonging to the wrong SmartObjectType. DDM-87524

Known Limitations

Known Limitations
LwM2M Gateway restart will restore all previously existing connections to Devices, but there is no guarantee that all Devices will be able to use restored connections. Some Devices may not be able to send notifications over restored connections.
It is not possible to import hardware types and templates that were exported from a version earlier than AppIoT_2018_35.
The Resource Attributes and their values on the Smart Object Template cannot be exported/imported between Device Networks.

Known Issues

Known Issue
TransformerDevice does not transform.
Auto observe trigger takes more than half a minute to complete after registration of a Device, but only first observation is impacted by this delay, following observation messages are on time.
Issue with paging of Firmware packages when a Device Type has more than 20 Firmware packages.
