Hi,

Can anyone guide me to learn the GROUP Control option in OM2M?

I have seen documentation to CRUD the GROUP. But I do not see the details about how to control the group members. For example a group of lights, after grouping them. how to turn ON?

I see that option in the screenshots of the LAMP CONTROL in https://wiki.eclipse.org/OM2M/Web_Interface, but no details!!

Please let me know how to turn-on/off a group of lights or any other actuators using GROUP option.

Thanks in anticipation.

My basic doubt is...

Do we create a group of RESOURCE NODE or do we create a group of URI as shown in the https://wiki.eclipse.org/OM2M/Web_Interface ?

In other words, to turn ON a group of lights, in the URI we can simply replace the GROUPNAME in place of the individual light name, and send the same command to the group of lights?

The screen shot is confusing me :(

I have created a lights group, and then trying to send the light control command for the group members. I am getting the following message for all the group members...

{
"m2m:rsc": 4103,
"m2m:rqi": "123",
"m2m:pc": "Current resource does not have any ACP attached",
"m2m:to": "admin:admin",
"m2m:fr": "/IN-CSE"
}

Any idea, how to over come this?
