Writing data using token
To support WRITE commands, devices must listen or SUBSCRIBE to the following topic.
${token}/${resourcepath}/${serialNumber}
Where resourcepath
is the identifier of the data item. The value received
in the PUBLISH message will be the value to be written.
The resource path is used by the Device to identify the data element to be written and
should conform to the /object/objectInstance/resource/resourceInstanceId
URI format as used when collecting data.
For example:
The device SUBSCRIBE to topic t8cwp2uneipj/parking/0/timer/8800002400000
to IMPACT.
IMPACT receives a request to write data to the device.
IMPACT sends a PUBLISH with topic
t8cwp2uneipj/parking/0/timer/8800002400000
with value 12.
The value 12 is received in IMPACT for the parking timer.
