CC2540 BLEBroadcaster官方例程抓包问题



如图所示,我运行的官方例程,advType = GAP_ADTYPE_ADV_SCAN_IND; // use scannable unidirected advertisements;

static uint8 advertData[] =
{
0x02, // length of this data
GAP_ADTYPE_FLAGS,
GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,

0x04, // length of this data including the data type byte

GAP_ADTYPE_MANUFACTURER_SPECIFIC, // manufacturer specific advertisement data type

1,
2,
3
};

为什么中间会有AVD_IND型数据包,后面的29字节的ADVdata是什么含义????

此包在代码的什么位置出现,作用是什么呢?
