Detailed Description

Read attributes command described in ZCL spec, subclauses 2.4.1 and 2.4.2.

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

ZB_ZCL_GENERAL_INIT_READ_ATTR_REQ(zcl_cmd_buf, cmd_ptr, ZB_ZCL_ENABLE_DEFAULT_RESPONSE);
ZB_ZCL_GENERAL_ADD_ID_READ_ATTR_REQ(cmd_ptr, ZB_ZCL_ATTR_BINARY_INPUT_PRESENT_VALUE_ID);
ZB_ZCL_GENRAL_SEND_READ_ATTR_REQ(zcl_cmd_buf, cmd_ptr, DUT_ADDR, DUT_ADDR_MODE, DUT_ENDPOINT,
 TH_ENDPOINT, ZB_AF_HA_PROFILE_ID,
 ZB_ZCL_CLUSTER_ID_BINARY_INPUT, NULL);

Read attributes response can be parsed as:

ZB_ZCL_GENERAL_GET_NEXT_READ_ATTR_RES(buf, read_attr_resp);

until allocated buffer space exceeds.

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