标题: nrf51822广播数据
您好，我是先接触的CC2541再转到的nrf51822.有关广播数据内容我想请教下？
在CC2541里，广播数据在数组里定义，比较直观
static uint8 advertData[] =
{
  0x02, // length of this data
  GAP_ADTYPE_FLAGS,
  DEFAULT_DISCOVERABLE_MODE | GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,

  // service UUID, to notify central devices what services are included
  // in this peripheral
  0x0c, // length of this data
  //GAP_ADTYPE_16BIT_MORE,    // some of the UUID's, but not all
  //LO_UINT16( SIMPLEPROFILE_SERV_UUID ),
  //HI_UINT16( SIMPLEPROFILE_SERV_UUID ),
  0x09,
  0x4d,
  0x54,
  0x4b,
  0x42,
  0x54,
  0x44,
  0x45,
  0x56,
  0x49,
  0x43,
  0x45,
};

但是在Nrf51822l里的static void advertising_init(void)
{
uint32_t    err_code;
ble_advdata_t advdata;
uint8_t    flags = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;

// YOUR_JOB: Use UUIDs for service(s) used in your application.
ble_uuid_t adv_uuids[] = {{BLE_UUID_BATTERY_SERVICE, BLE_UUID_TYPE_BLE}};

// Build and set advertising data
memset(&advdata, 0, sizeof(advdata));

advdata.name_type             = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance    = true;
advdata.flags.size             = sizeof(flags);
advdata.flags.p_data          = &flags;
advdata.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]);
advdata.uuids_complete.p_uuids  = adv_uuids;

err_code = ble_advdata_set(&advdata, NULL);
APP_ERROR_CHECK(err_code);
}
里我实在没找到具体明确的广播内容，通过抓包数据看ADvdata,真不知道他是怎么组织的广播包内容？请大家帮我看看

请问如何修改广播数据？我想在默认的格式下填几个字段

参考下ibeacon典型的广播设置：
宏定义：
[attach]1436[/attach]
函数：[attach]1435[/attach]

看到了，貌似所有自定义数据都要放到这个manuf_specific_data里吧？

而且我调试发现，如果想动态修改每次广播数据内容，是不是需要先停止广播再重新调用启动广播？因为我发现好像这个广播时初始化里配置好后就不再修改了，不知道哪里按照广播间隔一次次直接播原来内容
