我们的设备用GR5515芯片蓝牙。我们开发的APK上有时候蓝牙断开失败了。 断开是设备日志打印这样的错误 APP_E: (llc_con_upd_patch.c Line:159) [WARNING] Param0:9,Param1:8
EVT_Handler不处理disconnected时间，反而connection updated事件发生了。 APK上显示正常断开回复了。可以教一下这是什么原因，有没有解决方法？

AndroidStudio连接错误时报告这样的。 connected回应两次。然后自动断开了。 但是设备依然留着连接状态， APK上蓝牙搜不到的。

您好，
1、关于设备依然留着连接状态，APK上搜不到蓝牙：是因为你连接了两次，mClientIf=17和mClientIf=18，只有mClientIf=18断开了，mClientIf=17还在。您这边可以检查下为啥会连接2次。
2、mClientIf=17， Bad connection state: 4可参考以下代码： http://androidxref.com/9.0.0_r3/xref/frameworks/base/core/java/android/bluetooth/BluetoothGatt.java

谢谢， 问题解决了。 原来代码里面有连接两次部分。
不知道为什么这样链接了。 可以请教这个connect（0）和connect（1）有什么区别吗？
public void connectDevice() { if (!BLERequest.isBLEEnabled(appCtx)) { return; } if (targetDevice != null) { targetDevice.getGatt().connect(0).startProcedure(); if (!targetDevice.getGatt().connect(1).isStarted()) { targetDevice.getGatt().connect(1) .setTimeout(30000) .startProcedure(); } }}
