ZCL and BDB commands explenation

[JorgenM]

Hello,

I'm new to Nordic Zigbee solutions and where to find information so hoping someone can point me in right direction.

Using 2 nrf52840-DK boards. One is flashed with Nordic Zigbee Network coordinator example. The other is the Nordic Zigbee Ligh bulb example.
Using the example default configuration for libraries etc.
I use the BDB and ZCL commands to control coordinator through PuTTY terminal window. See screen shot.

1. Other than the terminal "help" for API commands syntax, is there some more detailed documentation available?
   I see a lot of ZCL_xx documented definitions but it's unclear how this related to what the valid ZCL and BDB commands are in terminal. Ex: "BDB start" starts a new PAN and open network for 180 sec for zigbee nodes to join.
2. Is there a "CLOSE" network BDB or ZCL or other command I can use? I don't want to wait 180 sec if device joins quickly. Any suggestions how to close the PAN with a command and not wait for time-out?
3. I was not able to make "ZCL attr" cmd to work. Are there there any examples of the command on how to read the attributes and clusters supported on a device (the Nordic Zigbee lightbulb as example) It should show support of LIGHT and ON/OFF/DIM. 
   I also tried reading a Securafi smart plug that connected to pan with no luck.

Thanks in advance!

Hi Marte,
Great! Sorry for late reply. Had to try to find some Nordic parts...:)
Yes I did see new version 1.9 come out. Hopefully some other new useful commands also.

I'm also looking for reference schematic for the interface between 52840 and the 21540 (PA). Is there a simpler version than the developer kit  version section? Have to trace it all out and can easily miss something.

Is there some documentation and examples on how to write to 52840 USB port (not the jlink in eval board) so I can configure the 21540 gain and perhaps some other "slow" parameters using the spi interface of the 52840?
I should be able to do that, right?

Thanks!

Hi,

Please create a new ticket with these questions as they are not related to the original issue in the ticket. Thanks!

Hi Marte, 

A bit late trying this and reply as I'm working through some of the Nordic lingo and documentation.
I use nrf Connect SDK 1.9.1 (for now), and VS, I like to use Kconfig GUI as much as possible.

I'm trying to find some reference or documentation that shows the BDB START (as example) shell commands and what it actually calls.
The shell document  doesn't actually describe what it calls 

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/libraries/zigbee/shell.html#bdb-start

So when you say "call the function" zb_bdb_close_network() what is the actual bdb command?
Looks like I may have to add this functions?

Perhaps there is a document how this is done or video tutorial?
I see reference to a bunch of functions that I can probably use but how do I implement them using shell commands?

Cheers,
Jorgen

Also this is all for Coordinator implementation using Network Coordinator example as starting point.

Hi,

When you issue the command bdb start you are calling the function cmd_zb_start, as you can see here. This function will set the device role and start the Zigbee thread (zigbee_enable).

There is no shell command that calls zb_bdb_close_network(), so you will have to implement that yourself. You can see how to create shell commands in Zephyr's documentation here: Zephyr shell. You can also take a look at how the Zigbee shell commands are implemented to have some examples.

Best regards,

Marte
