How to put nrf52832 in sleep mode?

[swetha Paladugu]

Hi,

I am using nrf52832 DK.

SDK 17.0.2 softdevice S132.

I am using freertos and running nrf52832 as a peripheral.

I want to put nrf52832 in sleep mode.

I am new to this Sleep concepts. Firstly what are the different sleep modes available and how to use them in the application?

My requirement is, I want to keep the nrf52832 in ultra deep sleep to consume power as less as possible. But it should be always advertising and nrf52832 should wake up for any gpio interrupt.

How to do this? Is there any example project available? Can anyone help me to achieve my requirement?

Hi

No, you won't be able to advertise while in low power mode. You can check out the guide for optimizing power on nRF52 designs here for more details on what you can do to minimize current consumption during advertising (lowering TX power and tweaking advertising parameters for instance).

Best regards,

Simon
