【问题描述】

CtsVerifier-Bluetooth-LE-SEcure-ClientServer-Test测试pass但是无法选择Pass-Button
工具版本：9.0-r11
其他信息：
上个版本正常，verifier版本相同
分析过程中结合代码咨询测试，印证只有Client无法选中，Server正常

【问题结论】

蓝牙驱动修改引入，已定位回退,需要bsp进一步修改

verifier的该项测试流程：
Client测试pass后做出先关闭mAdapter.disable()后打开mAdapter.enable()的动作，
经梳理蓝牙框流程发现，蓝牙关闭后再次打开超时失败，由此导致verifier的该项测试Activity无法收到广播将按钮设置为可选enable

【分析详细】

Bluetooth-LE-SEcure-ClientServer-Test

流程概述
1.启动BleSecureClientStartActivity
该测试页面只是一个activity-ui。主要的方法实现和流程动作都在父类Activity中，重点关注父类。
2.调用父类BleClientTestBaseActivity的onCreate()完成：
页面显示
设置底部pass-fail-button按键的监听
设置pass-button为disable不可选
初始化页面的测试项ListView
回到子类继续onCreate():
显示info提示信息的dialog
启动BleClientService准备测试

3.调用父类BleClientTestBaseActivity的onResume():
注册测试服务BleClientService的广播监听BroadcastReceiver mBroadcast

4.开始测试
这个测试是俩设备Server-Client配对测试，自动触发，细节略，和Server端之间的蓝牙通信有关
listview每一条测试结束都会有广播发出，接收广播后将mPassed做或运算，如果一切顺利mPassed的运算结果是PASS_FLAG_ALL
这代表测试项全部通过

private static final int PASS_FLAG_ALL = 0x3FFFF;

然后Client端将蓝牙关闭mAdapter.disable()再打开mAdapter.enable()，打开成功情况下Activity才会将Pass-Button设置为可选择
由于驱动代码出问题，遂enable()失败，无法设置按钮可选

测试代码
1.测试Activity，提供ui无业务代码
cts/apps/CtsVerifier/src/com/android/cts/verifier/bluetooth/BleSecureClientStartActivity.java
2.上面(1)的父类，测试结果处理
cts/apps/CtsVerifier/src/com/android/cts/verifier/bluetooth/BleClientTestBaseActivity.java
3.测试Service，真正的测试项执行
cts/apps/CtsVerifier/src/com/android/cts/verifier/bluetooth/BleClientService.java
