Power management modes.

[jyoti yadav]

Hi, 

I wanted to know that is there any example code for the power management. how we can enter into the stanby mode and how to come back to active mode, time required for that. i wanted measure the current consumption in standby mode and how i can achieve that? Which are the peripherals we can enable and disable in deep sleep mode and how to come from deep sleep mode to active mode, time required for that.

Hello

You'll probably want to have a look at this sample:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/boards/nrf/system_off/README.html

Which are the peripherals we can enable and disable in deep sleep mode

That depends on what board you are using, but either way you'll find that kind of information here: https://infocenter.nordicsemi.com/index.jsp

Best regards,

could you please suggest example code for the standby Doze mode which given in data sheet, i can see there are different name in the example they are using could you clarify which mode is what as per data sheet?

Please specify what chip you are using, otherwise I don't know what datasheet you're referring too.

I am using BL653 Liard.

So you're using the nRF52833:

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52833%2Fkeyfeatures_html5.html&cp=5_1_0

• Flexible power management
  • 1.7 V to 5.5 V supply voltage range
  • On-chip DC/DC and LDO regulators with automated low current modes
  • Automated peripheral power management
  • Fast wake-up using 64 MHz internal oscillator
  • 0.6 µA at 3 V in System OFF mode, no RAM retention
  • 1.5 µA at 3 V in System ON mode, no RAM retention, wake on RTC

All this should be demonstrated in the System Off demo.

What do you mean by doze mode?

What data sheet are you referring to?
