Handling Permit Join

[MartinPersson]

Hello.

I'm trying to improve the permit join-handling in our project. Right now we're simply hammering the zBoss stack with bdb_start_top_level_commissioning(ZB_BDB_NETWORK_STEERING), but I'd like to do it with a bit more finesse.

When permit join is enabled and when it times out and disables I get a ZB_NWK_SIGNAL_PERMIT_JOIN_STATUS, however I can't see if there's any indication in the callback if the network is opened or closed. Signal status is always 0 (OK) and that's the only information I can figure out exists.

Now, as I've understood timeout for permit join is hard coded to 3 minutes. I can live with that, but my questions are:

1. Is there a way to see if the network is open or closed? Either in the callback or by an API call to zBoss?
2. Is it possible to turn off permit join or will it always run for 3 minutes?

Regards

Hi Martin, and thanks for reaching out.

This will probably not make too much of a difference, but what SDK version are you using?

1. Is there a way to see if the network is open or closed? Either in the callback or by an API call to zBoss?

You could use the ZB_NWK_SIGNAL_PERMIT_JOIN_STATUS signal handler for this, as the permit_duration contains this info.

2. Is it possible to turn off permit join or will it always run for 3 minutes?

I think you should be able to close the network using zb_bdb_close_network().

Sorry for late reply.
Zboss version is 3.11.1.5. SDK I'm a bit unsure about since the build system has a bad habit of hiding the details. If you tell me what file to look in I can give you more detailed information.

I'm right now refactoring the code base (it's grown a bit untamed) so it's a bit hard to test your suggestions at the moment, but I will try to do it during next week.

Hi,

I was thinking what Nordic SDK you were using. If you are for instance using the Thread & Zigbee add-on SDK for nRF5 SDK I would urge you to switch to NCS instead, as the the old Zigbee and Thread SDK is deprecated.
