ZigBee: implement callback called before attribute report reported because of Configure Report command

Ok,

then I would like to raise a feature request: it would be nice to have a macro:

ZB_ZCL_REGISTER_PRE_REPORT_CB

which will allow to register a callback which is called before sending a Attribute Report Response.

Hi,

I understand what you are asking about now, but unfortunately no there is such callback. What you could do is read ZB_ZCL_GET_REPORTING_FLAG(rep_info, ZB_ZCL_REPORT_ATTR) after each zboss_main_loop_iteration() and then taking the measurement. The rep_info you can get from

zb_zcl_reporting_info_t* zb_zcl_find_reporting_info(  zb_uint8_t ep,

                                                      zb_uint16_t cluster_id,

                                                      zb_uint8_t cluster_role,

                                                      zb_uint16_t attr_id);

The problem with this is that you never know if somebody subscribed to reporting through attribute value changes instead of periodically report, so there could be a case when you don't measure the value at all.

Hi,

I know how to use attribute reporting. This is not what I asked for. I asked for synchronization between the Attribute Reporting and taking a measurement. In the multi_sensor example, the measurement is taken each one second. This is nonsense for me - why should I wake up my chip each one second if the attribute is reported each ten minute. I want to take the measurement just before reporting the attribute. This is what I asked for. I need some callback to be called just before reporting an attribute. There is nothing about that in the multi_sensor examples and in the CLI example.

Hi,

Have you taken a look at how attribute reporting is implemented in the multi_sensor and the CLI example in the SDK? I think this will give you a good starting point for implementing temperature reporting.
