Power Down Sensor Circuits
This command switches off the power supply of the sensor circuits.
Command:
#PDWN
↵
Response:
#PDWN

This command can be used for some power saving during idle operation periods. Note,
that the sensor circuits are automatically powered up again, if the module receives any
command (e.g. MEA) requiring a sensor measurement. This is also the case if a broadcast
measurement takes place.

Enter Deep Sleep Mode
This command puts the device into a deep sleep mode with very low power
consumption
Command:
#STOP
↵
Response:
#STOP
↵
During deep sleep mode the device has very low power consumption. No standard
communication via USB/UART is possible. The deep sleep mode can be only exit by
sending a <CR> (0x0D) to the device. The device will respond then also with a single
<CR> indicating that it is ready to receive new commands. The wake-up duration can be
up to 250 ms.
