State

The /osc/state API returns state attributes of the camera. The difference between this and the info API is that state contains mutable values representing camera status ( batteryLevel , for example), while the info contains only static attributes of the camera (for example, manufacturer or attributes that don’t change often like firmwareVersion) .

Input

This command takes no input.

Output

Name	Type	Description
`fingerprint`	String	Fingerprint (unique identifier) of the current camera state.
`state`	Object	A JSON object containing the status of various the camera states. See the next table.

`state` object

This JSON object provides the status of various camera states. Manufacturers can provide new, custom states, which should be prefixed with an underscore ( _ ) to prevent namespace collisions.

Name	Type	Description
`sessionId`	String	ID of the current session. This field was deprecated in API level 2.
`batteryLevel`	Number	Expressed as a floating point value of the battery remaining, e.g. 0.5
`storageChanged`	Boolean	True if a new type of storage (e.g. a SD card or a USB drive) is inserted/removed. This field was deprecated in API level 2.
`storageUri`	String	A unique identifier to distinguish different storages. It is used to tell if the storage has changed or not. This field was added in API level 2.
`_vendorSpecific`	[type](optional)	Vendor specific additional state about the camera. Prefix with an underscore ( _ ) to prevent namespace collisions.
