BLE CC2541 修改广播信号

BLE CC2541修改广播信号
读取设备的 MAC 地址：
[html] view plaincopy
GAPRole_GetParameter(GAPROLE_BD_ADDR, ownAddress);  
[html] view plaincopy
#define GAPROLE_BD_ADDR             0x304  //！< Device's Address. Read Only. Size is uint8[B_ADDR_LEN]. This item is read from the controller.  
因为微信协议规定 advertData 中要有设备的 MAC 地址，所以要将读到的 MAC 地址放到 advertData 中：
[html] view plaincopy
        advertData[ADVERT_MAC_ADDR+0] = ownAddress[5];  
        advertData[ADVERT_MAC_ADDR+1] = ownAddress[4];  
        advertData[ADVERT_MAC_ADDR+2] = ownAddress[3];  
        advertData[ADVERT_MAC_ADDR+3] = ownAddress[2];  
        advertData[ADVERT_MAC_ADDR+4] = ownAddress[1];  
        advertData[ADVERT_MAC_ADDR+5] = ownAddress[0];  
        ownAddress[5] = advertData[ADVERT_MAC_ADDR+5];  
        ownAddress[4] = advertData[ADVERT_MAC_ADDR+4];  
        ownAddress[3] = advertData[ADVERT_MAC_ADDR+3];  
        ownAddress[2] = advertData[ADVERT_MAC_ADDR+2];  
        ownAddress[1] = advertData[ADVERT_MAC_ADDR+1];  
        ownAddress[0] = advertData[ADVERT_MAC_ADDR+0];  
        GAPRole_SetParameter( GAPROLE_ADVERT_DATA, sizeof( advertData ), advertData );  
最后要重新设置 GAPROLE_ADVERT_DATA
微信客户端是通过扫描 BLE 设备的 MAC 地址并连接
