cc2540 usb 广播

可能是进入休眠了，要一直广播的话，建议关闭power saving，并按照下面设置：
#define DEFAULT_DISCOVERABLE_MODE GAP_ADTYPE_FLAGS_GENERAL //非限制广播

static uint8 advertData[] =
{
// Flags; this sets the device to use limited discoverable
// mode (advertises for 30 seconds at a time) instead of general
// discoverable mode (advertises indefinitely)
0x02, // length of this data
GAP_ADTYPE_FLAGS, //无限广播
DEFAULT_DISCOVERABLE_MODE | GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,

// service UUID, to notify central devices what services are included
// in this peripheral
0x03, // 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 ),

};
