It's not easy to do in cli mode. There are many requests and responses. This chip manufacturer really feels bad

no no 。。。Nobody does that. It's a bad example. It doesn't help.I have been in contact with zigbee and ble mesh for a month, but there is no help. Many developers of NXP chips have completed the project, and I am still walking in the same place.

Hi,

You can find the Zigbee functions that are called in the CLI example if you open the project. In components/zigbee/cli/zigbee_cli_cmd_zdo.c you can find the zdo functins, such as "zdo bind on".

On line 1816-1831 is a list of the different commands, and the last parameter in the NRF_CLI_CMD() call is the function that is called. So the "zdo bind on" calls m_sub_bind (this is not the last entry, but it is used to differentiate between bind on and bind off). Which again calls cmd_zb_bind on line 1811 in the same file.

The zcl commands are listed in zigbee_cli_cmd_zcl.c. As you can see, the zcl_subscribe on calls m_sub_subscribe() -> cmd_zb_subscribe(), which is found in components/zigbee/cli/zigbee_cli_cmd_attr_report.c.

Reports are received by a function cli_agent_ep_handler_report , which gets called from cli_agent_ep_handler which is registered in main function of cli_agent_router example with ZB_AF_SET_ENDPOINT_HANDLER macro.

I hope this can be of help. Let me know how it goes!

Best Regards,

Marjeris
