zigbee

[SkyC]

HI 

After the connection between the light-bulb and the Zigbee-Coordinator is completed, it is observed from Sniffer that both parties will broadcast regularly (as shown in the screenshot below), and there are some questions:
1. Is there a way to describe the 5bytes payload?
2. What are the functions of the broadcast packets on both sides?

Hi,

1. In this example, where in the source code is the Zigbee (RF) packet received for parsing?

This depends on the packet type. The reception of packets are handled inside the ZBOSS stack, which is only available as a linkable library. Relevant application packages are provided to the configured callbacks. The raw RF packages are not available to the application.

2. In this example, when executing as Coordinator, what are the corresponding clusters that can be processed?

Since the CLI agent example works with clusters through cluster IDs directly, it should be able to process any clusters defined in the ZCL specification.

3. In this example, where in the source code is the place to distinguish RF packet attributes (profile/cluster/attribute/command...)?

Not sure I understand this question. Like I said in 1., the packets are passed to the relevant callbacks in the application. Please have a look at the documentation in Zigbee stack API overview.

Best regards,
Jørgen
