蓝牙连接

如何实现自动连接

if ( events & START_DEVICE_EVT )
{
// Start the Device
VOID GAPCentralRole_StartDevice( (gapCentralRoleCB_t *) &simpleBLERoleCB );

// Register with bond manager after starting device
GAPBondMgr_Register( (gapBondCBs_t *) &simpleBLEBondCB );

return ( events ^ START_DEVICE_EVT );
}

if ( events & START_DISCOVERY_EVT )
{
SIMPLEPROFILE_UUID_X = SIMPLEPROFILE_CHAR6_UUID;
simpleBLECentralStartDiscovery();

osal_start_timerEx(simpleBLETaskId,START_SCAN_EVT,300);
return ( events ^ START_DISCOVERY_EVT );
}

if ( events & START_SCAN_EVT ) //自动开始搜索

我看在蓝牙程序中初始化后，立即执行了这个事件，

 osal_set_event( simpleBLETaskId, START_DEVICE_EVT );

我在if ( events & START_DISCOVERY_EVT )
{
SIMPLEPROFILE_UUID_X = SIMPLEPROFILE_CHAR6_UUID;
simpleBLECentralStartDiscovery();

osal_start_timerEx(simpleBLETaskId,START_SCAN_EVT,300); ///添加扫描

return ( events ^ START_DISCOVERY_EVT );
}

但是无法扫描啊 

Barbara Wu：

注意看SimpleBLECentral例程里面

对向上按键的操作中如何打开扫描的
