我需要用BLE按钮创建应用程序。我在RPi3上使用了简单的ab shutter和java应用程序。但tinyB并没有找到正确的主服务。然后我试着在bluez和gatttool的原生工具中寻找它。有人能帮忙吗：Blues 5.65正确连接到设备。然后info命令打印设备上的所有服务，gatttool也是。但命令列表属性只显示其中的一部分。特征，我需要-HID(00001812-0000-1000-800-000805f9b34bb(。如何在列表属性中找到它？原因tinyB库只显示前的列表

通过在单元文件(/lib/systemd/system/bluetooth.service(中添加--noplugin=input，hog at exec ，解决了问题
