power consumption in Idle

[ran]

Hi, 

We are starting to measure the power of our nrf52840 based design.

I'd like to establish the power number for Idle() , since system will be in Idle() most of the time. 

For that , I have used the following code, invoked from CLI : 

__disable_irq();
sd_app_evt_wait();

1. Is this code correct for keeping system in Idle() ? 

2. What Is the estimated nrf52840 SoC current consumption in this mode ?  

3. Our code is based on UART example

Thanks, 

Ran

Hi Ran

Deep sleep will generally save more power. Just keep in mind that that sets the chip in system OFF mode, which means it can't have a timer running while sleeping. It can only be awoken by resets and button events, etc.

Please see the Sleep section I linked to in my first reply on this ticket for more info on the system OFF mode current consumption.

Best regards,

Simon
