About SDK v2.9 Bluetooth scanning power consumption

SDK v2.6, Bluetooth scanning : 6.54mA

SDK v2.9, Bluetooth scanning : 11.56mA

What could be the problem?

Hi Leo,

Are you using the same board and sample for these?

Is it a custom board or the nRF52840DK?

Is it your own sample or an nRF application?

Regards,

Priyanka

Hi Leo,

Looks like in the latest release the enabling of DCDC has been changed from via KConfig to via Devicetree. 

You can take a look at how it's done in the migration guide.

Please try this an let me know if the current consumption goes down.

Hi Priyanka,

Thank you! This problem is solved.

And the code should be:

/* DCDC (HV mode) */
&reg0 {
    status = "okay";
};
/* DCDC */
&reg1 {
	regulator-initial-mode = < NRF5X_REG_MODE_DCDC >;
};
