busctl call "led method" failed

[Vishwanatha Subbanna]

Hi harley,

I am able to see it working. Please check if there was any typo etc.. journalctl would have the info

root at rain4bmc:~# busctl --verbose  call xyz.openbmc_project.LED.GroupManager /xyz/openbmc_project/led/groups/power_on org.freedesktop.DBus.Properties Get ss xyz.openbmc_project.Led.Group Asserted
MESSAGE "v" {
        VARIANT "b" {
                BOOLEAN false;
        };
};

root at rain4bmc:~# busctl --verbose  call xyz.openbmc_project.LED.GroupManager /xyz/openbmc_project/led/groups/power_on org.freedesktop.DBus.Properties Set ssv xyz.openbmc_project.Led.Group Asserted b true 

root at rain4bmc:~# busctl --verbose  call xyz.openbmc_project.LED.GroupManager /xyz/openbmc_project/led/groups/power_on org.freedesktop.DBus.Properties Get ss xyz.openbmc_project.Led.Group Asserted
MESSAGE "v" {
        VARIANT "b" {
                BOOLEAN true;
        };
};

root at rain4bmc:~# busctl --verbose  call xyz.openbmc_project.LED.GroupManager /xyz/openbmc_project/led/groups/power_on org.freedesktop.DBus.Properties Set ssv xyz.openbmc_project.Led.Group Asserted b false

root at rain4bmc:~# busctl --verbose  call xyz.openbmc_project.LED.GroupManager /xyz/openbmc_project/led/groups/power_on org.freedesktop.DBus.Properties Get ss xyz.openbmc_project.Led.Group Asserted
MESSAGE "v" {
        VARIANT "b" {
                BOOLEAN false;
        };
};

root at rain4bmc:~# 

Alternatively, you could use bustle set-property 

busctl set-property xyz.openbmc_project.LED.GroupManager /xyz/openbmc_project/led/groups/power_on xyz.openbmc_project.Led.Group Asserted b true

busctl get-property xyz.openbmc_project.LED.GroupManager /xyz/openbmc_project/led/groups/power_on xyz.openbmc_project.Led.Group Asserted

Thanks,
!! Vishwa !!
