Detailed Description

Discover attributes command described in ZCL spec, subclauses 2.4.13 and 2.4.14.

Read attributes request command can be formed and sent as in following snippet:

ZB_ZCL_GENERAL_DISC_ATTR_REQ(zcl_cmd_buf, cmd_ptr, ZB_ZCL_ENABLE_DEFAULT_RESPONSE,
ZB_ZCL_ATTR_BINARY_INPUT_PRESENT_VALUE_ID, 5,
DUT_ADDR, DUT_ADDR_MODE, DUT_ENDPOINT,
TH_ENDPOINT, ZB_AF_HA_PROFILE_ID, ZB_ZCL_CLUSTER_ID_BINARY_INPUT, NULL);

Discover attributes response can be parsed as:

ZB_ZCL_GENERAL_GET_COMPLETE_DISC_RES(buf, complete);
ZB_ZCL_GENERAL_GET_NEXT_DISC_ATTR_RES(buf, disc_attr_info);

until allocated buffer space exceeds.

Discover attributes request parsing and response filling and sending is implemented in ZCL library internal functions.

Discovery attribute response and returns next Discovery attribute status record or NULL if there is no more data.

If response contains invalid data, NULL is returned.

Parameters
data_buf- ID zb_bufid_t of a buffer containing part of Discover attribute response data
disc_attr_info- out pointer to zb_zcl_disc_attr_info_t, containing Discover attribute status record
Note
data_buf buffer should contain Discover attribute response payload, without ZCL header. Each parsed Discover attribute status record is extracted from initial data_buf buffer
