我正在制作 android BLE 应用程序。根据文件，我提出申请。我的问题是，有时应用程序会运行良好，但有时会抛出错误。有 2 个日志，一个用于成功，第二个用于错误。每次蓝牙断开连接时，我都会发送关闭方法。我不知道我被困在哪里。

第一次成功日志

最佳答案

发生的问题由我解决。

我看到有很多与状态 8 和 22 相关的问题发生在我们连接到设备时。我是说这是状态 8 和 22 的确切答案，但在某些情况下这将是原因。

发生这种情况是因为当我们成功发现服务后，我们写入描述符并立即调用 ondescripte 覆盖方法，然后进行读写操作。那么会发生什么，不执行一个进程可能会产生这些问题。

我发现的解决方案效果很好。总是尝试使活套处理程序 ，以便我延迟完成一次执行。

       new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {
                            @Override
                            public void run() {
                                mBluetoothGatt.writeDescriptor(RTS_CCCD); //for descriptor
  //  or
    mBluetoothGatt.readCharacteristic(brspInfo); //for read
//or
    mBluetoothGatt.writeCharacteristic(brspInfo); //for write
                            }
                        }, 500);

为什么和什么状态 8 问题 here .

为什么和什么状态 22 问题 here .

关于android - 蓝牙 Gatt 问题 onClientConnectionState() - status=8 clientIf=29，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45027406/
