What's the maximum number of nodes supported by nrf52840 as CLI Zigbee coordinator ?

[cai_2020]

I'm using the cli_agent_router example in nRF5 SDK for Thread and Zigbee v3.2.0 /4.0

I have a few questions:

1. If the end node needs to join in the designated coordinator, is there any way other than using the Install code?  example: assign PANID at end node when join operation?

2.How to make the coordinator always allow nodes to join, default only open 3 minutes at the beginning.

3.The  cli coordinator example  can support 50 end nodes?

Hi,

1) You don't need to use install code for a end node to join a coordinator. As long as the coordinator you want to join allows joining of new devices you will be able to join.

2) The 180 seconds commissioning window is defined by the Zigbee specification, I don't recommend changing the commissioning window. In the CLI example you start commissioning by calling "bdb start" at any time.

3) Do you ask about maximum amount of children of a coordinator, or the maximum number of nodes in the network? In all our examples you can set the maximum number of children for a coordinator or router using zb_set_max_child(). The default maximum value of children nodes for a parent in the ZBOSS stack is 32.

Thanks,

Without manually open the coordinator, can I configure the EP to only automatically join a certain coordinator?

Hi,

I am not sure what you mean by "manually open the coordinator", but coordinator needs to start the commissioning process to let other device join the network. The commissioning process is defined by the Zigbee BDB specification.
