9.3.10. Notifications about the Changes of the Properties
When the value of a property is changed and the user is subscribed to the node that the property belongs to,
an asynchronous notification is generated. This notification is called the 'change message'. The format of
such a message is very similar to the response for the GET command:
æ CHG /EDID.EdidStatus=F48:E1
A Short Example of How to Use the Subscription
There are two independent users controlling the device through two independent connections (Connection #1
and Connection #2). The events in the rows occur after each other.
ç OPEN /MEDIA/AUDIO/O3
æ o- /MEDIA/AUDIO/O3
ç GET /MEDIA/AUDIO/O3.VolumePercent
æ pm /MEDIA/AUDIO/O3.VolumePercent=100.00
ç GET /MEDIA/AUDIO/O3.VolumePercent
æ pw /MEDIA/AUDIO/O3.VolumePercent=100.00
æ SET /MEDIA/AUDIO/O3.VolumePercent=50.00
æ pw /MEDIA/AUDIO/O3.VolumePercent=50.00
æ CHG /MEDIA/AUDIO/O3.VolumePercent=50.00
The first user (Connection #1) set a subscription to a node. Later, the other user (Connection #2) made a change,
and thanks to the subscription, the first user got a notification about the change.
