【問題描述】
CtsVerifier-Bluetooth-LE-SEcure-ClientServer-Test測試pass但是無法選擇Pass-Button
工具版本：9.0-r11
其他資訊：
上個版本正常，verifier版本相同
分析過程中結合程式碼諮詢測試，印證只有Client無法選中，Server正常
【問題結論】
藍芽驅動修改引入，已定位回退,需要bsp進一步修改
verifier的該項測試流程：
Client測試pass後做出先關閉mAdapter.disable()後開啟mAdapter.enable()的動作，
經梳理藍芽框流程發現，藍芽關閉後再次開啟超時失敗，由此導致verifier的該項測試Activity無法收到廣播將按鈕設定為可選enable

【分析詳細】
Bluetooth-LE-SEcure-ClientServer-Test
流程概述
1.啟動BleSecureClientStartActivity
該測試頁面只是一個activity-ui。主要的方法實現和流程動作都在父類Activity中，重點關注父類。
2.呼叫父類BleClientTestBaseActivity的onCreate()完成：
頁面顯示
設定底部pass-fail-button按鍵的監聽
設定pass-button為disable不可選
初始化頁面的測試項ListView
回到子類繼續onCreate():
顯示info提示資訊的dialog
啟動BleClientService準備測試
3.呼叫父類BleClientTestBaseActivity的onResume():
註冊測試服務BleClientService的廣播監聽BroadcastReceiver mBroadcast
4.開始測試
這個測試是倆裝置Server-Client配對測試，自動觸發，細節略，和Server端之間的藍芽通訊有關
listview每一條測試結束都會有廣播發出，接收廣播後將mPassed做或運算，如果一切順利mPassed的運算結果是PASS_FLAG_ALL
這代表測試項全部通過
private static final int PASS_FLAG_ALL = 0x3FFFF;
然後Client端將藍芽關閉mAdapter.disable()再開啟mAdapter.enable()，開啟成功情況下Activity才會將Pass-Button設定為可選擇
由於驅動程式碼出問題，遂enable()失敗，無法設定按鈕可選
測試程式碼
1.測試Activity，提供ui無業務程式碼
cts/apps/CtsVerifier/src/com/android/cts/verifier/bluetooth/BleSecureClientStartActivity.java
2.上面(1)的父類，測試結果處理
cts/apps/CtsVerifier/src/com/android/cts/verifier/bluetooth/BleClientTestBaseActivity.java
3.測試Service，真正的測試項執行
cts/apps/CtsVerifier/src/com/android/cts/verifier/bluetooth/BleClientService.java
