Dbus 可调温度计间隔特性设置错误

我试图设置一个可调温度计的间隔属性，遇到了一些问题

我已经测试了设置属性，例如NetworkManager中的WimaxEnabled属性：

$ gdbus call --system --dest org.freedesktop.NetworkManager \
--object-path /org/freedesktop/NetworkManager \
--method org.freedesktop.DBus.Properties.Set \
 "org.freedesktop.NetworkManager" "WimaxEnabled" "<boolean false>"
()

$ gdbus call --system --dest org.freedesktop.NetworkManager \
--object-path /org/freedesktop/NetworkManager \
--method org.freedesktop.DBus.Properties.Set \
"org.freedesktop.NetworkManager" "WimaxEnabled" "<boolean true>"
()

我还编写了一个C程序来实现这一点，结果完全相同，0起作用，其他值每失败一次。有人见过这个吗？你有什么建议吗

编辑：

我在发帖后不久就意识到了这个问题，这是不可避免的。我认为最小和最大属性是区间的范围。由于两者都设置为0，我显然无法将Interval属性设置为0以外的任何值

$bgdbus call --system --dest org.bluez \
--object-path /org/bluez/hci0/dev_00_07_80_A6_3A_CA \
--method org.freedesktop.DBus.Properties.Set \
"org.bluez.Thermometer1" "Interval" "<uint16 0>"
()

$ gdbus call --system --dest org.bluez \
--object-path /org/bluez/hci0/dev_00_07_80_A6_3A_CA \
--method org.freedesktop.DBus.Properties.Set \
"org.bluez.Thermometer1" "Interval" "<uint16 1>"
