Hi,

I don not know what SDK version you are using, but this is written assuming SDK v4.4.2.

You should be able to achieve this functionality by changing the while loop to something like this:

nrf_gpio_port_write(LED_PORT, 1 << (output_state + LED_OFFSET));
output_state = (output_state + 1) & BLINKY_STATE_MASK;
nrf_delay_ms(30);
nrf_gpio_port_write(LED_PORT, 1 << (output_state + LED_OFFSET));
output_state = (output_state + 1) & BLINKY_STATE_MASK;
nrf_delay_ms(10);

Best regards,
Jørgen

This does not correspond with the information you gave in the initial post. PCA10001 is nRF51 series, and there is no such directory (C:\Keil_v5\ARM\Device\Nordic\nrf51822\Board\pca10001) related to SDK 12.2.0. Please use latest SDK (14.2.0), and the blinky example projects found in examples\peripherals\blinky\pca10040\blank\.

hi,

 in sdk 14.2 in blinky example. try something like this in your main loop.

nrf_gpio_pin_set(LED_1);

nrf_delay_ms(30);

nrf_gpio_pin_clear(LED_1);

nrf_delay_ms(10);
