Parses Report attribute command and returns next Attribute report or NULL if there is no more data.

If command contains invalid data, NULL is returned.

Parameters

data_buf	- ID zb_bufid_t of a buffer containing Report attribute command data
rep_attr_req	- out pointer to zb_zcl_report_attr_req_t, containing Attribute report

Note

data_buf buffer should contain Report attribute command payload, without ZCL header. Each parsed Attribute report attribute is extracted from initial data_buf buffer

Note

Report attribute command contains variable number of attribute reports, zb_zcl_report_attr_req_t defines one attribute report
