不能将Marshmallow中的套接字移动扫描仪与最新的扫描API (在Lollipop中与旧API一起工作得很好)

Question

我切换到Marshmallow，并将扫描API更新为10.2.1.0版本。它在棒棒糖很好，但我有一些困难，更新应用的Marshmallow。我使用的是以下扫描仪模型：SocketMobile CHS 8Ci。工厂重置(通过扫描用户指南中的条形码)，然后将其设置为SPP模式(通过扫描用户指南中的另一个条形码)。我通过安卓设置->蓝牙将智能手机与其配对。

现在在我的应用程序中:我认为扫描API初始化OK (以前在旧API中有一个测试序列，但现在它已经消失了)。但是，我得到了NOTIFY_SCANPI_INITIALIZED，我没有看到任何错误。但是，当我的应用程序与扫描仪失去连接时，出现了一些问题。

下面是我的应用程序内部配对的logcat：

后来发生了一些奇怪的事。我去Android设置，忘了设备。单击“刷新”，设备将不再出现在列表中。为了在列表中看到它，我不得不工厂重置它，并将它放回SPP模式。

我认为这是不允许的。它需要全球定位系统许可并打开手机的全球定位系统。Ps:在Android6.0之后，您需要在运行时请求权限。
