LEDs could be either active high or active low. You can try to change LEDS_ACTIVE_STATE to 1 in pca10040.h.

Yes, the blinking works. But when I connect the dev kit with my smartphone and the nRF Connect App the LED is off. Usually it should be on. After disconnecting the LED blinks correctly again.

Could you modify #define LED_STOP 20 to 22? Please let me know this helps or not.

Okay thanks. I changed the pin number to GPIO pin 22 to see if the external connected LED starts blinking for advertising but the external LED stays on the whole time. Do I have to change other parts in the code?

Code from pca10040.h

// LEDs definitions for PCA10040
#define LEDS_NUMBER    4

#define LED_START      17
#define LED_1          22
#define LED_2          18
#define LED_3          19
#define LED_4          20
#define LED_STOP       20

Hi,

The nRF52832DK Buttons and LEDs use the GPIOs from P0.13 to P0.20. Its definitions are in the <nRF5_SDK>\components\boards\pca10040.h. You can take a look.
