CC2541 No Display No Keyboard 配对鉴权问题

大家好：

将SimpleBLEPeriphral工程SBP初始化函数改为如下配置：

  // Setup the GAP Bond Manager
  {
    uint32 passkey = 0; // passkey "000000"
    uint8 pairMode = GAPBOND_PAIRING_MODE_INITIATE;
    uint8 mitm = TRUE;
    uint8 ioCap = GAPBOND_IO_CAP_NO_INPUT_NO_OUTPUT;
    uint8 bonding = TRUE;
    GAPBondMgr_SetParameter( GAPBOND_DEFAULT_PASSCODE, sizeof ( uint32 ), &passkey );
    GAPBondMgr_SetParameter( GAPBOND_PAIRING_MODE, sizeof ( uint8 ), &pairMode );
    GAPBondMgr_SetParameter( GAPBOND_MITM_PROTECTION, sizeof ( uint8 ), &mitm );
    GAPBondMgr_SetParameter( GAPBOND_IO_CAPABILITIES, sizeof ( uint8 ), &ioCap );
    GAPBondMgr_SetParameter( GAPBOND_BONDING_ENABLED, sizeof ( uint8 ), &bonding );
  }

更改后，手机与设备配对时，会弹出配对请求窗口，但手机只需要点击确定或取消。但是即使点击确定，需要鉴权的Characteristic 5还是读不出值。

请问能否实现ioCap仅为No input No output，点击手机配对的确定后即可鉴权成功读出CHAR 5的值？
