ubisys Compact7B Stack Changes between 2.4.0 and 3.0.0
Added support for I2C TAP
Added support for a unified and fully configurable join/rejoin algorithm with back-offs and retries at the stack level
Reject trust center rejoin on a distributed security network (CSA incident no. 2021-ZP-0401)
Start TCLK exchange if an end device could not successfully finish TCLK exchange during its initial joining and has just rejoined
Improved sleep management: Checking both transmission and reception queues for pending packets, if necessary
Extended the advanced parent link maintenance mechanism by the new criterion “poor poll control reactivity”
More granular startup progress notifications, including kick-off of a Touch Link commissioning procedure
Stop ongoing join/rejoin retry attempts when Touch Link commissioning procedure is instigated
Encapsulated the All Hubs cluster’s dependency on the Touch Link server, IAS Zone server and Time client clusters, for better modularity
Added Enhancements to the Thermostat cluster
Made the hard limit for the scene table capacity configurable
Added support for the Relative Humidity Measurement cluster
Added framework support for initiating enroll request and IAS zone status change indication via the ZCL request queue
Added framework support for time query initiated by a Time client cluster
Prohibit automatic CIE detection by default; application is still able to instigate it though should legacy systems require it
Explicitly stop fast polling mode as soon as no more response frame is pending
Resume network activity if a router device just failed a rejoin attempt
Enhancement: PAN-ID and permit joining state changes are forwarded to application clusters
Bug-fix: Under rare circumstances, a frame might linger in the transmission queue without being actually sent
Bug-fix: Potential overflow of 64-bit timer values might occur when unsigned arithmetic is used for comparison of due times
Bug-fix: During MAC association, if an unrelated frame is being received via data polling, MAC association might be incorrectly terminated; account for this case and retry if permissible
Bug-fix: Periodical polling timer used to be unconditionally kept alive, even in case of data poll failure; temporarily cancel it to avoid interference with subsequent retry attempts. Once succeeded, the periodical polling timer will be reinstated for its normal usage.
Bug-fix: When assessing MAC capability changes for a rejoining device verify the “Device Type” and “Receiver on when Idle” bits only
Bug-fix: Skip route discovery table verification diagnostics in case of an end device
Bug-fix: Limit the use of incoming APS security material to few select cases only
Bug-fix: Periodical reporting on a cluster attribute could lead to undue delays of reports for other clusters
Bug-fix: Startup behavior of the OnOff cluster might be incorrect due to interactions with Level Control or Color Control clusters on the same application endpoint
Bug-fix: Brightness adjustment of the Level control cluster might be incorrect due to interactions with a Color Control cluster on the same application endpoint
Bug-fix: Under rare circumstances, neighbor table entries might be incorrect (caused by a typo)
Bug-fix: Under rare circumstances, out-of-sequence or truncated OTA data block could result in failed OTA download attempts
