Zigbee Subscribing attribute limitation

[Dhaval Dalvadi]

If we subscribe all attributes of cluster of device connects to coordinator will it make issue?
we have noticed its dropping many values if subscribed at same time. if values are changed it reflects but if no changes in value and it reaches at max interval set instead of getting all values which are not changed it just gets few values 

Is it normal or any settings needs to be done?

Hi, 

What NCS version are you using?

How and what do you set the maximum and minimum reporting interval?

[Dhaval Dalvadi]

NCS 2.7.0

minimum 0 and maximum 2 minutes for attribute subscription

is there any limitation or max recommended attributes for subscription ?

In coordinator I can have 5 router/end devices connected and it can have 10-20 attributes to subscribe for each

Hi, 

Which clusters and attributes are you subscribing to, and if the interval set up such that the attributes are supposed to be reported simultaneously, i.e., the max interval is reached simultaneously for all the attributes?

if values are changed it reflects but if no changes in value and it reaches at max interval set instead of getting all values which are not changed it just gets few values

Has there been a report (due to changes in values) before this that happened less than 2 minutes ago? Attributes shall be reported after the maximum interval since the last report, so if there was a report due to the value changing in between the periodic reports, then the next report will be 2 minutes after the value change report, and not 2 minutes after the periodic report. 

It would also be useful with a sniffer log, so please provide a sniffer log to investigate the issue. Thanks.

Amanda.
