sleep

Usage

>> sleep [ confirmation = true | false ]

Security

Description

Immediately shuts down communications and implements any power saving measures which are possible, over-riding the 10-second timeout which normally invokes these actions (see Section Timeouts, Output Blanking and Power Saving). Power saving measures typically include:

• any interface circuitry used for a Serial link,
• sensor channels activated only for the purpose of satisfying a fetch command.

Any scheduled sampling activity is not affected. The sleep command does not attempt to power down a USB link, because there is always enough power available via USB to run the logger's basic functions; sensor channels used for a fetch command will still be shut down.

If used without any parameters, the command generates no error messages, and always succeeds silently; there is no prompt or confirmation message.

Firmware versions 1.116 or later support an optional confirmation parameter.  If this is used with a value of true, a confirmation message is generated, but no prompt.

• confirmation = true | false  When a confirmation is asked for using 'confirmation = true', the sleep command will respond with 'sleep status = sleeping' before entering sleep mode.
