Zigbee Feature Request: Create API to access binding table

RE: Zigbee Feature Request: Create API to access binding table

Got an update today on something I was unaware of from one of our Zigbee experts:

We're already using an API like this in the zdo mgmt_bind shell command (documentation). We think this should cover your needs, as you can use this command to read the binding table of local and remote devices. Check out the subsys/zigbee/lib/zigbee_shell/src/zigbee_shell_cmd_zdo.c, too see how the command is implemented and how the API is being used in the nRF Connect SDK. ZBOSS API documentation for binding management: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/zboss/3.11.2.0/group__zdo__bind.html

The best practice is to not touch internal structs (like gc_aps_bind_src_table) directly.

Best regards,

Simon

Unfortunately this won't be prioritized at this time, as the Zigbee project is currently only in maintenance mode. Very sorry about that, and it does not look like we will make any changes to the ZBOSS stack that will require a new ZBOSS integration.

Best regards,

Simon

Unfortunately, we have not had any progress on this case but I have pinged the devs. If you need to escalate the case further, please contact the regional sales manager of your area to do so, as I can't do more on my end. If you don't know how to get in touch with the RSM, fill out the sales related questions form here, and add a link to this ticket in your request.

Best regards,

Simon

Hi, do you have any updates on the issue?

Accessing the binding table and/ or handling binding requests are a basic feature required by the Zigbee spec, to my unterstanding. I don't think it's necessarily a new feature that needs to be implemented in the stack, but maybe a lack of documentation? I simply need a proper way to access the local binding table of my device. Unfortunately, this issue now became a blocker for my evaluation.

Kind regards,
Peter

Thank you Peter

The internal ticket is no ongoing, but I don't see it being addressed in the next few days I'm afraid. It might take a week or two before I have an update for you. Thank you for your patience!

Best regards,

Simon

Hi Simon, thanks for your quick answer.

The workaround described by Marte is certainly some kind of workaround, but not a proper way to access the Zigbee binding table. The workaround accesses an internal variable (

gc_aps_bind_src_table

) of the ZBOSS library that is not mentioned or documented anywhere and doesn't show any reliable behaviour.

This issue is for the ZBOSS library which is included in both the nRF Connect SDK and nRF5 SDK, so I don't suppose that maintenance mode is a problem.

Kind regards,

Peter

Just to make sure I understand, the actual workaround is described in the link you provided where Marte explains the binding tables, correct? And you want a feature request to add this to the Zigbee nRF5 SDK?

The nRF5 SDK as explained in this statement is moved to maintenance mode, so I can't guarantee that this feature will be added any time soon, but I'll definitely make the request to our development team.

Best regards,

Simon

Sorry, wrong link, the workaround was actually described here: Binding an nrf52 Zigbee light switch to a light bulb
