求助：关于IBeacon

我用微信摇一摇周边摇不到自己的设备，信息如下，请问有什么问题吗？  10055 =0x2747, 19495=0x4c27

你使用的 手机是安卓还是苹果，我记得用微信摇一摇，广播数据的长度需要调整，安卓的要少一位，苹果的少一位和多一位都可以使用，最后一个字节的数据

下面是微信的测试摇一摇，肯定摇得到，其他跟微信相关的属于应用问题，需要自己去看微信的标准改了。

//微信的测试摇一摇
static uint8 advertData[] =
{
  // Preamble: 0x4c000215
  // 02 01 06 1A FF 4C 00 02 15: iBeacon prefix (fixed)
  // UUID: E2C56DB5-DFFB-48D2-B060-D0F5A71096E0
  // Major: 1 (0x0001)
  // Minor: 1 (0x0001)
  // Measured Power: -59 (0xc5)

安装 TI 官方的 CC254x 开发环境
复制 C:\Texas Instruments\BLE-CC254x-1.3.2\Projects\ble\SimpleBLEBroadcaster 文件夹
粘贴到：C:\Texas Instruments\BLE-CC254x-1.3.2\Projects\ble\iBeacon
运行 IAR Embedded Workbench，点击 File > Open > Workspace
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[] =
{
 // 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,
 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。
Select Project > Clean to clean the project.
Select Project > Make to make the project.
Select Project > Download and Debug to send the code to the CC2540 Key Fob
Select Debug > Go to Run the code on the CC2540 Key Fob.

这是非连接设备，可以开通微信摇一摇功能：http://wenku.baidu.com/view/32f3e91ccaaedd3383c4d3f1.html
