Typedef Documentation

zb_zdo_ieee_addr_req_t

typedef struct zb_zdo_ieee_addr_req_s zb_zdo_ieee_addr_req_t

Parameters of IEEE_addr_req primitive.

To be put into buffer as data (means - after space alloc).

zb_zdo_ieee_addr_resp_t

typedef struct zb_zdo_ieee_addr_resp_s zb_zdo_ieee_addr_resp_t

Function Documentation

zb_zdo_ieee_addr_req()

zb_uint8_t zb_zdo_ieee_addr_req	(	zb_uint8_t	param,
		zb_callback_t	cb
	)

IEEE_addr_req primitive.

Parameters

param	- index of buffer with primitive parameters zb_zdo_ieee_addr_req_s. Parameters must be put into the buffer as data (allocated).
cb	- user's function to call when got response from the remote.

Returns

- ZDP transaction sequence number or 0xFF if operation cannot be performed now (nor enough memory, resources, etc.)

Example:

{
  zb_zdo_ieee_addr_req_param_t *req = NULL;
  zb_uint8_t tsn;
 
  req = ZB_BUF_GET_PARAM(buf, zb_zdo_ieee_addr_req_param_t);
 
  req->nwk_addr = ind->src_addr;
  req->dst_addr = req->nwk_addr;
  req->request_type = ZB_ZDO_SINGLE_DEV_RESPONSE;
  req->start_index = 0;
  tsn = zb_zdo_ieee_addr_req(buf, ieee_addr_callback);
 
  if (tsn == ZB_ZDO_INVALID_TSN)
  {
    TRACE_MSG(TRACE_ZDO2, "request failed", (FMT__0));
  }
}
 
void ieee_addr_callback(zb_uint8_t param)
{
  zb_bufid_t buf = param;
  zb_zdo_nwk_addr_resp_head_t *resp;
  zb_ieee_addr_t ieee_addr;
  zb_uint16_t nwk_addr;
  zb_address_ieee_ref_t addr_ref;
 
  TRACE_MSG(TRACE_ZDO2, "zb_get_peer_short_addr_cb param %hd", (FMT__H, param));
 
  resp = (zb_zdo_nwk_addr_resp_head_t*)zb_buf_begin(buf);
  TRACE_MSG(
      TRACE_ZDO2, "resp status %hd, nwk addr %d", (FMT__H_D, resp->status, resp->nwk_addr));
  ZB_DUMP_IEEE_ADDR(resp->ieee_addr);
  if (resp->status == ZB_ZDP_STATUS_SUCCESS)
  {
    ZB_LETOH64(ieee_addr, resp->ieee_addr);
    ZB_LETOH16(&nwk_addr, &resp->nwk_addr);
    zb_address_update(ieee_addr, nwk_addr, ZB_TRUE, &addr_ref);
  }
  zb_buf_free(buf);
}

zb_zdo_nwk_addr_req()

zb_uint8_t zb_zdo_nwk_addr_req	(	zb_uint8_t	param,
		zb_callback_t	cb
	)

Sends NWK_addr_req primitive.

Parameters

param	- index of buffer with primitive parameters - zb_zdo_nwk_addr_req_param_s
cb	- user's function to call when got response from the remote. zb_zdo_nwk_addr_resp_head_s passed to cb as parameter.

Returns

- ZDP transaction sequence number or 0xFF if operation cannot be performed now (nor enough memory, resources, etc.)

Example:

{
  zb_bufid_t buf = param;
  zb_uint8_t tsn;
  zb_zdo_nwk_addr_req_param_t *req_param = ZB_BUF_GET_PARAM(buf, zb_zdo_nwk_addr_req_param_t);
 
  req_param->dst_addr = 0;
  zb_address_ieee_by_ref(req_param->ieee_addr, short_addr);
  req_param->request_type = ZB_ZDO_SINGLE_DEVICE_RESP;
  req_param->start_index = 0;
  tsn = zb_zdo_nwk_addr_req(param, zb_get_peer_short_addr_cb);
 
  if (tsn == ZB_ZDO_INVALID_TSN)
  {
  TRACE_MSG(TRACE_ZDO2, "request failed", (FMT__0));
  }
}
 
void zb_get_peer_short_addr_cb(zb_uint8_t param)
{
  zb_bufid_t buf = param;
  zb_zdo_nwk_addr_resp_head_t *resp;
  zb_ieee_addr_t ieee_addr;
  zb_uint16_t nwk_addr;
  zb_address_ieee_ref_t addr_ref;
 
  TRACE_MSG(TRACE_ZDO2, "zb_get_peer_short_addr_cb param %hd", (FMT__H, param));
 
  resp = (zb_zdo_nwk_addr_resp_head_t*)zb_buf_begin(buf);
  TRACE_MSG(TRACE_ZDO2, "resp status %hd, nwk addr %d", (FMT__H_D, resp->status, resp->nwk_addr));
  ZB_DUMP_IEEE_ADDR(resp->ieee_addr);
 
  // additionally check tsn if needed
  //if (resp->tsn == my_saved_tsn)
 
  if (resp->status == ZB_ZDP_STATUS_SUCCESS)
  {
  ZB_LETOH64(ieee_addr, resp->ieee_addr);
  ZB_LETOH16(&nwk_addr, &resp->nwk_addr);
