Integrate Zigbee Green Power devices into Nordic Coordinator

[sjf]

Hi,

We have been working with a Zigbee coordinator based on nRF52840 with nRF5_SDK_for_Thread_and_Zigbee_v4.0.0_dc7186b, Softdevice and FreeRTOS.

We are tring to integrate to the Zigbee network some Dusun devices (PIR sensors, leakage sensors, etc). These devices send some Green Power requests on init.

Is this supported on ZBOSS stack to be integrated by a nRF52840 based coordinator?

Thanks in advance,

Santiago

Hi Santiago,

You can find which Zigbee standards are supported in the ZBOSS stack here. There you can see that there's support for Zigbee PRO Green Power feature. For detailed information n which features have been implemented in the stack, you can check out the following Protocol Implementation Conformance Statement (PICS): ZigBee PRO Layer PICS and Stack Profile 6 and Errata for GP Basic PICS.

You can also check out the file zboss_api_zgp.h for the ZGP (Zigbee Green Power) API, which can be found in \external\zboss\include.

Best regards,

Marte

Thanks Marte, is there any example from Nordic related to Green Power?

Hi Santiago,

No, we don't have any Zigbee Green Power examples in the SDK. We have support for Green Power and an API for it, but you'll have to implement it yourself using the ZGP API.

Hi Marte,

Sorry for the late response. We are periodically receiving the message Channel Request when the device is in "pairing mode".

The coordinator sends a Permit Join Request but there is no signal or update from Zboss stack.

How this has to be handled?

Hi Santiago,

I'm sorry for the late response on my part as well. I have been trying to look into your problem, but I can't tell what the problem is. Permit Join request is a part of the association process, and enables and disables permit join in the network. In the examples in the SDK, such as the light control example, the coordinator enables permit join for 180 seconds, which is the time window where nodes can join the network. Is the problem that nothing happens after the coordinator has enabled permit join, and that no nodes are able to join the network, or is it something else?

This process shouldn't be any different when using the Green Power cluster. Have you compared how you're doing the association process etc. in your application with how it's done in the examples?

Best regards,

Marte

Hi Marte,

Yes, other devices can join normally. It seems that the Dusun device does not join to the network by some reason.

Hi Santiago,

I don't know which Dusun device you have, but I found two Dusun IoT gateways on the Zigbee alliance website (1 and 2). From their compliance documents I could tell that they both use the IAS Zone cluster. Unless you have implemented this in your application, these devices will not be able to join your network, as the IAS Zone cluster adds more security, and you must perform IAS Zone enrollment in order to be able to connect. We do have support for the cluster in the SDK, and you can find the documentation here. However, we don't have any examples with IAS Zone as of now. If you decide that you want to implement this, you should take a look at the Zigbee Cluster Library specification, specifically the chapter about implementation guidelines. You can also take a look at this DevZone case.

Best regards,

Marte

Hi Marte,

Thanks for your response.

The IAS Zone behavior appears once the device has joined the network. By the way, our project does support it.
