Zigbee Coordinator and EndNode

[abe]

Hello, I'm developing a BLE peripheral + Zigbee Coordinator, starting from ble_zigbee_dynamic_template of nRF5 SDK for Thread and Zigbee v3.1.0.
Both applications (BLE and Zigbee) work properly. Now I need to have the Zigbee EndNode list and configuration to populate the BLE Gatt database.
How can I make this?
I'm looking to ZDO api, for example the zb_zdo_simple_desc_req functions, but the program goes on fault function "zb_nrf52840_abort" (like some other ZDO functions)
Where I wrong?
Regards
Abele

Hi Abele,

With Zigbee EndNode do you mean Endpoint? Do you want a list of the zigbee endpoints of a given destination address?

For this kind of things I recommend testing it first out with the CLI example and taking a look at the Zigbee CLI reference documentation page. You can use CLI command "zdo match_desc" if you want to sent a matching description request to all nodes in a network, and then you could parse the response to obtain the EP list. I also found a command called "zdo active_ep" which I think you can use if you already know the short address of the device. I recommend trying out these functions with the CLI example to see how they work and find which one fits your application best.

Afterwards you can take a look at the source code in the CLI example to take a look at how these functions are implemented, see inside zigbee_cli_cmd_zdo.c, for example function cmd_zb_match_desc is the one sending out the match descriptor request.

Best regards,

Marjeris

Hello mam i am working on zigbee+ble uart color dimmable light example in that example and  i have flash the  board after flash the board i am getting bluettoth connection and zigbee connection but i can't able to control the bulb 

how to control the bulb ? stilll i need to add any code please reply me a soon as possible
