怎么解释gapRole_AdvertData？
static uint8 gapRole_AdvertData[B_MAX_ADV_LEN] =
{
0x02, // length of this data
GAP_ADTYPE_FLAGS, // AD Type = Flags
// Limited Discoverable & BR/EDR not supported
(GAP_ADTYPE_FLAGS_GENERAL | GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED),
0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
};
问题1：这个data的长度怎么是2？
问题2：后面那些0是什么?
