Bind switch to coordinator bind error - how to debug? (TZ-1134)

[mw75]

Question

I'm implementing a Zigbee to Can-Bus bridge. Can-bus to Power-Plug is working by a modified Zigbee_Light_Switch example.

Now i try to get actions/attribute updates from a switch/remote. I can read the cluster list from the simple description, but when i try to bind the on-Off-cluster to the coordinator i just get an error in the bind callback.

How to debug what's wrong?

I have registered an action handler and expect calls when the switch button is pressed. Is this a valid assumption?

Additional context.

You can print out the value of zdo_status and check the defination of esp_zb_zdp_status_t to identify the reason for the zdo request failure.

Going over the code you provided, I'm suspecting that you populated a wrong request destionation address.

bind_req.req_dst_addr = esp_zb_get_short_address();

I believe it should be the peer address you want the request to be sent to.
