LP-CC2652RB: 发送周期广播数据失败

wj s

Part Number: LP-CC2652RB

我按照SimpleLink CC13x2 / CC26x2 SDK BLE5-Stack User's Guide 2.02.01.00中周期广播那节的指导步骤进行外设设备的代码编写，

但主机centor设备无法接收到通过GapAdv_SetPeriodicAdvData函数设置的周期广播数据，但可以接收到GapAdv_loadByHandle设置的数据。附上外设设备配置周期广播部分的代码段如下，各函数返回的status我已经检查过，都返回了SUCCESS

经过在论坛搜索，我找到了之前的一个帖子[参考译文] LAUNCHXL-CC26X2R1：BTool 中发送周期性广播包的正确方法是什么？ - Bluetooth®︎（参考译文帖）(Read Only) - Bluetooth®︎（参考译文帖） - E2E 设计支持 (ti.com)，问题描述与我目前的现象基本一样，目前我仍没有找到问题原因和解决方法。

您好，

您必须在 simple_central 进行一些额外的代码修改才能捕获周期性广告。这些修改写在了 Synchronize with a Periodic Advertising Train 部分中。您是否实施了这些步骤？

抱歉，上周没有及时回复您。

附上我的simple_central代码

初始化相关代码如下：

void SimpleCentral_scanCb(uint32_t evt, void* pMsg, uintptr_t arg)
{
  uint8_t event;

  if (evt & GAP_EVT_ADV_REPORT)
  {
    event = SC_EVT_ADV_REPORT;
  }
  else if (evt & GAP_EVT_SCAN_ENABLED)
  {
    event = SC_EVT_SCAN_ENABLED;
  }
  else if (evt & GAP_EVT_SCAN_DISABLED)
  {
    event = SC_EVT_SCAN_DISABLED;
  }
  else if (evt & GAP_EVT_INSUFFICIENT_MEMORY)
  {
    event = SC_EVT_INSUFFICIENT_MEM;
  }
  else
  {
    return;
  }

  if(SimpleCentral_enqueueMsg(event, SUCCESS, pMsg) != SUCCESS)
  {
    ICall_free(pMsg);
  }
}

GapScan_registerCb(SimpleCentral_scanCb, NULL);

// Set Scanner Event Mask
GapScan_setEventMask(GAP_EVT_SCAN_ENABLED | GAP_EVT_SCAN_DISABLED |
                   GAP_EVT_ADV_REPORT);

// Set Scan PHY parameters
GapScan_setPhyParams(DEFAULT_SCAN_PHY, SCAN_TYPE_PASSIVE,
                   DEFAULT_SCAN_INTERVAL, DEFAULT_SCAN_WINDOW);

// Set Advertising report fields to keep
temp16 = (SCAN_ADVRPT_FLD_ADDRESS | SCAN_ADVRPT_FLD_ADDRTYPE);
GapScan_setParam(SCAN_PARAM_RPT_FIELDS, &temp16);
// Set Scanning Primary PHY
temp8 = SCAN_PRIM_PHY_1M;
GapScan_setParam(SCAN_PARAM_PRIM_PHYS, &temp8);
// Set LL Duplicate Filter
temp8 = SCAN_FLT_DUP_ENABLE;
GapScan_setParam(SCAN_PARAM_FLT_DUP, &temp8);

temp16 = SCAN_FLT_PDU_NONCONNECTABLE_ONLY;
GapScan_setParam(SCAN_PARAM_FLT_PDU_TYPE, &temp16);

// Set initiating PHY parameters
// INIT_PHYPARAM_MAX_CONN_INT = 80
GapInit_setPhyParam(INIT_PHY_1M, INIT_PHYPARAM_CONN_INT_MIN,
				  INIT_PHYPARAM_MIN_CONN_INT);
GapInit_setPhyParam(INIT_PHY_1M, INIT_PHYPARAM_CONN_INT_MAX,
				  INIT_PHYPARAM_MAX_CONN_INT);

在SimpleCentral_processAppMsg函数中关于SC_EVT_ADV_REPORT广播扫描报告事件的处理中，我加了打印，第一个现象是没看到pAdvRpt->periodicAdvInt != 0的周期广播数据，第二个现象是发现了我的simple_peripheral设置的GapAdv_loadByHandle广播数据，代码如下：

static void SimpleCentral_processAppMsg(scEvt_t *pMsg)
{
  bool safeToDealloc = TRUE;

  if (pMsg->hdr.event <= APP_EVT_EVENT_MAX)
  {
    BLE_LOG_INT_STR(0, BLE_LOG_MODULE_APP, "APP : App msg status=%d, event=%s\n", 0, appEventStrings[pMsg->hdr.event]);
  }
  else
  {
    BLE_LOG_INT_INT(0, BLE_LOG_MODULE_APP, "APP : App msg status=%d, event=0x%x\n", 0, pMsg->hdr.event);
  }

  switch (pMsg->hdr.event)
  {
    case SC_EVT_KEY_CHANGE:
      SimpleCentral_handleKeys(pMsg->hdr.state);
      break;

    case SC_EVT_ADV_REPORT:
    {
      GapScan_Evt_AdvRpt_t* pAdvRpt = (GapScan_Evt_AdvRpt_t*) (pMsg->pData);
        if(0 != pAdvRpt->periodicAdvInt)
        {
         // this is a periodic advertisement
            Display_printf(dispHandle, SC_ROW_9, 0, "this is a periodic advertisement");
            SimpleCentral_doStopDiscovering(0);
        }
        else
        {
         // this is NOT a periodic advertisement
        }
        // reporting the advData according to the peripheral address
        if(pAdvRpt->addr[0] == 0x8c && pAdvRpt->addr[5] == 0x74) { // this is my peripheral address
            Display_printf(dispHandle, SC_ROW_NON_CONN, 0, "Discovered: %s", Util_convertBdAddr2Str(pAdvRpt->addr));
            int j = 0;
            Display_printf(dispHandle, SC_ROW_9 + 1, 0, "advertisement data len: %d", pAdvRpt->dataLen);
            for(j = 0; j < pAdvRpt->dataLen; j++) {
                Display_printf(dispHandle, SC_ROW_9 + 2 + j, 0, "%x", *(pAdvRpt->pData + j));
            }
        }
      

      // Free report payload data
      if (pAdvRpt->pData != NULL)
      {
        ICall_free(pAdvRpt->pData);
      }
      break;
    }
    
    // ...
    
    default:
      // Do nothing.
      break;
}

根据 Synchronize with a Periodic Advertising Train中的步骤来看，目前我在第六步遇到了问题，无法识别到periodic advertisers
