In the absence of any further reply from Swathy, I thought others may find this useful as we worked it out for ourselves.

Connect the PPK II to the DK as shown in the image:

1- From P1 on the PPK II:
Black → GND
Brown → P22 (VDD_nRF – the pin farthest from the USB connector)
Red → P22 (VDD_nRF – the pin closest to the USB connector)
2- Set SW6 to “nRF ONLY”.
3- Leave SW9 in the middle position (VDD on-board).
4- Leave SW10 in the off position.
5- Power the board by connecting a USB cable.
6-In the Power Profiler app, set the device to Ammeter mode, enable, and press Start to begin measuring current.

#include <zephyr/kernel.h>
#include <zephyr/sys/poweroff.h>
#include <zephyr/drivers/gpio.h>

static const struct gpio_dt_spec led = GPIO_DT_SPEC_GET(DT_ALIAS(led0), gpios);


int main(void)
{
    int ret;
	bool led_state = true;

	if (!gpio_is_ready_dt(&led)) {
		return 0;
	}

	ret = gpio_pin_configure_dt(&led, GPIO_OUTPUT_ACTIVE);
	if (ret < 0) {
		return 0;
	}

    for(int i=0; i < 10; i++)
    {
        gpio_pin_toggle_dt(&led);
        led_state = !led_state;
		k_msleep(200);
    }

    gpio_pin_configure_dt(&led, GPIO_DISCONNECTED);



    // Minimal init only
    k_sleep(K_FOREVER);
    // or: sys_poweroff();

    return 0; 
}

Thank you Swathy,

Please can you confirm SW6, SW9 and SW10 positions as these are not mentioned in any of the URLs you have provided (which I had already read) or in your reply above.

Regards

Ian

Hi Ian,

The procedure is as follows:

Cut the solder bridge SB40 as mentioned here: Set up the DK

You can either use the Ampere meter mode or source meter mode to measure the current. For Source meter mode make the following connection (Refer:Measuring current in Source Meter mode):

And for Ampere meter mode, the connection is as follows (Refer:Measuring current in Ampere Meter mode):

The board must be powered using an external power source (like usb, coin cell, etc.) when using the Ampere meter mode.

Regards,

Swathy
