I'm a Fiware user and i deployed an orion context broker GE , cepheus GE and an iotagent-ul instances in different VMs on cloud. I have registered a device in the iot agent specifying a command attribute in the register request and its corresponding entity was created in the context broker on the registration process. Now when i register a device with its attributes and the command attribute with its name and type , the device is registered on the iot agent and its entity is also created in the context broker . But the strange thing that happens is that the command attribute is only translated into its special attributes which are the commandName_info and commandName_status but the command attribute itself is not shown among them in the registration result in the iot agent logs .In addition, when i do an update operation on the command attribute in the Orion context broker , the attribute is not recognized and the update fails as the command attribute is missing in the entitiy itself . And the registration process is as follows:
- this is the registration request that i send :
(curl -v -H 'content-type: application/json' -H 'fiware-service: ourservicename' -H 'fiware-servicepath: /ourservicpath' -X POST 'http://iotagentULaddress:8080/iot/devices' -d @- ) << EOF
{
"`devices`": [
{
"device_id": "controller12",
"entity_name": "labcontroller12",
"entity_type": "Controller",
"isPattern" :"false",

}]
}
EOF
And this is the registration result in the iot agent's logs showing the registered entity and how it is created in the context broker:

It's now clear that the command attribute is not created but only its special attributes that describe the command state itself but there's no command to be updated . So , Is my registration request composed correctly to suit the iotagen-ul instance especially for its interpretation for the command ? and how could i verify the registration correctness ? and i just want to know where the problem could lie exactly . and thanks so much.
