BlueZ 与 GATTtool 主要服务列表

Question

我需要使用 BLE 按钮创建应用程序。我在 RPi3 上使用简单的 ab 快门和 java 应用程序。但是tinyB没有找到正确的主要服务。然后我尝试在 bluez 和 gatttool 的本机工具中查找它。有人可以帮忙吗： BlueZ 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 也是如此。但命令 list-attributes 只显示其中的一些。我需要的特征 - HID (00001812-0000-1000-8000-00805f9b34fb)。我如何在列表属性中找到它？因为tinyB 库仅显示 ex 的列表。

Answer 1

通过在单元文件（/lib/systemd/system/bluetooth.service）配置蓝牙服务并在 exec 中添加 --noplugin=input,hog 来解决问题
