修改源代码
simpleBLEBroadcaster.c
// GAP - Advertisement data (max size = 31 bytes, though this is
// best kept short to conserve power while advertisting)
static uint8 advertData[] =
{
// Flagsthis 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,
GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,
// three-byte broadcast of the data "1 2 3"
0x04, // length of this data including the data type byte
GAP_ADTYPE_MANUFACTURER_SPECIFIC, // manufacturer specific advertisement data type
1,
2,
3
}
修改下面关键字
UID: E2C56DB5-DFFB-48D2-B060-D0F5A71096E0
Major: 1 (0x0001)
Minor: 1 (0x0001)
Measured Power: -59 (0xc5)
// GAP - Advertisement data (max size = 31 bytes, though this is
// best kept short to conserve power while advertisting)
static uint8 advertData[] =
{
// 25 byte ibeacon advertising data
// Preamble: 0x4c000215
// UUID: E2C56DB5-DFFB-48D2-B060-D0F5A71096E0
// Major: 1 (0x0001)
// Minor: 1 (0x0001)
// Measured Power: -59 (0xc5)
0x1A, // length of this data including the data type byte
GAP_ADTYPE_MANUFACTURER_SPECIFIC, // manufacturer specific advertisement data type
0x4c,
0x00,
0x02,
0x15,
0xe2,
0xc5,
0x6d,
0xb5,
0xdf,
0xfb,
0x48,
0xd2,
0xb0,
0x60,
0xd0,
0xf5,
0xa7,
0x10,
0x96,
0xe0,
0x00,
0x01,
0x00,
0x01,
0xc5
}
接下来修改广播类型，将下面代码
//uint8 advType = GAP_ADTYPE_ADV_NONCONN_IND// use non-connectable advertisements
uint8 advType = GAP_ADTYPE_ADV_DISCOVER_IND// use scannable unidirected advertisements
修改为
uint8 advType = GAP_ADTYPE_ADV_NONCONN_IND // use non-connectable advertisements
//uint8 advType = GAP_ADTYPE_ADV_DISCOVER_IND// use scannable unidirected advertisements
接下来修改 GAP
// Set the GAP Role Parameters
GAPRole_SetParameter( GAPROLE_ADVERT_ENABLED, sizeof( uint8 ), &initial_advertising_enable )
GAPRole_SetParameter( GAPROLE_ADVERT_OFF_TIME, sizeof( uint16 ), &gapRole_AdvertOffTime )
GAPRole_SetParameter( GAPROLE_SCAN_RSP_DATA, sizeof ( scanRspData ), scanRspData )
GAPRole_SetParameter( GAPROLE_ADVERT_DATA, sizeof( advertData ), advertData )
GAPRole_SetParameter( GAPROLE_ADV_EVENT_TYPE, sizeof( uint8 ), &advType )
因为 iBeacon 必须不间断广播，并且不响应任何数据请求，所以我们要修改 GAPROLE_ADVERT_OFF_TIME 和 GAPROLE_SCAN_RSP_DATA。
// Set the GAP Role Parameters
GAPRole_SetParameter( GAPROLE_ADVERT_ENABLED, sizeof( uint8 ), &initial_advertising_enable )
//GAPRole_SetParameter( GAPROLE_ADVERT_OFF_TIME, sizeof( uint16 ), &gapRole_AdvertOffTime )
//GAPRole_SetParameter( GAPROLE_SCAN_RSP_DATA, sizeof ( scanRspData ), scanRspData )
GAPRole_SetParameter( GAPROLE_ADVERT_DATA, sizeof( advertData ), advertData )
GAPRole_SetParameter( GAPROLE_ADV_EVENT_TYPE, sizeof( uint8 ), &advType )
保存工程后，进行编译，并通过 CCDebugger 下载程序到开发板中。
