> +Question:+
> Ultralight 2.0 commands with parameters (polling mode)
> +Description:+
> I have found some troubles working with commands. According to the sintaxis of the protocol, a command can be executed using an updateContext operation to the Orion Context Broker, which now it is working perfect.
> The doubt is, how do I give the command some parameters, as specified in the protocol?
> <device name>@<command name>|<param name>=<value>|....
> If I send the following REST request, it gives me a 400 Bad request, complaining about strange characters:
> curl -X PUT \
>   'http://MYIP:1026/v2/entities/1111/attrs/blink?type=Thing' \
>   -H 'cache-control: no-cache' \
>   -H 'content-type: application/json' \
>   -H 'fiware-service: howtoservice' \
>   -H 'fiware-servicepath: /howto' \
>   -d '{
>     "type": "command",
>     "value": "blink=true|another_param=false"
> }'
> Where should I issue the params if it is not in the "value" key?
> If I use the following request, it acts as expected:
> curl -X PUT \
>   'http://MYIP:1026/v2/entities/1111/attrs/blink?type=Thing' \
>   -H 'cache-control: no-cache' \
>   -H 'content-type: application/json' \
>   -H 'fiware-service: howtoservice' \
>   -H 'fiware-servicepath: /howto' \
>   -d '{
>     "type": "command",
>     "value": "true"
> }'
> Thanks in advance
