Read the signal of ack in Zigbee

Hi Andreas,

I was asking because I was reading wrong values in the attr_id. But I understand now why: the message that I'm trying to parsing is the default response that I enabled. So the payload is not like the struct "zb_zcl_write_attr_res_t", but like "zb_zcl_default_resp_payload_t".

Now the parsing is correct.

Thank you so much and best regards,

Raffaela

Hi.

[quote user="Raffaela"]My question is: in the struct "zb_zcl_write_attr_res_t", what is the "attr_id" field?[/quote]

"attr_id" is the ID of the attribute.

Best regards,

Andreas

Hi Andreas,

I'll explain the context better: from the coordinator I send a command of this type: ZB_ZCL_WINDOW_COVERING_SEND_GO_TO_TILT_PERCENTAGE_REQ.

I enable Default Response.

The device receives this message.

At this point, the device sends back the response to the Coordinator that I can intercept declaring, on the Coordinator, the callback I posted before: zcl_device_cb.

My question is: in the struct "zb_zcl_write_attr_res_t", what is the "attr_id" field?

Thank you and best regards,

Raffaela

Hi again Raffaela.

Are you only looking for the MAC acknowledge?

If you want to make sure that the value have changed, you should configure the reporting so that the device is notified about changes to the value. You can use a simple read attribute command to read the value of the attribute.

Could you explain some more about what you want to achieve?

Best regards,

Andreas

Hi Andreas,

Actually I understood what the problem was.

I was looking for the Default Response because I wanted to be sure that the request sent by the Zigbee Coordinator was actually executed by the device.

I will briefly explain my way to obtain the parsing of the Default Response by the Zigbee Coordinator:

After sending the write attribute request through a specific command by the Coordinator to the Router, the Router executes the command and sends the Default Response back to the Zigbee Coordinator.

To read the Default Response, I have to register the callback to handle the ZCL commands

ZB_AF_SET_ENDPOINT_HANDLER(HA_WINDOW_CONTROLLER_ENDPOINT, zcl_device_cb

When it arrives, I do this:

zb_zcl_write_attr_res_t * p_attr_resp;
zb_uint8_t status_resp = 0;

static zb_void_t zcl_device_cb(zb_uint8_t param)
{
    zb_buf_t                       * p_buffer = ZB_BUF_FROM_REF(param);
    zb_zcl_parsed_hdr_t * p_cmd_info = ZB_GET_BUF_PARAM(p_buffer, zb_zcl_parsed_hdr_t);

    ZB_ZCL_GET_NEXT_WRITE_ATTR_RES(p_buffer, p_attr_resp);

    status_resp = p_attr_resp->status;
}

My question is: In the struct "zb_zcl_write_attr_res_t", what is the "attr_id" field?

Is it correct my approach?

Thank you and best regards,

Raffaela

Hi.

I think this case got lost in the queue, I've just got it assigned to me.

I looks similar to the case I already have with you, so lets keep the discussion there.

Best regards,

Andreas
