Thank you for your kind and quick reply. I have a mistake in pin assignment. LED3 and 4 are well controlled.

Could you try configuring and toggling the LEDs manually using the GPIO abstraction functions, to check if there are some issues in the code or with the board?

#include "nrf_gpio.h"

#define BOARD_LED_3 19
#define BOARD_LED_4 20

nrf_gpio_cfg_output(BOARD_LED_3);
nrf_gpio_cfg_output(BOARD_LED_4);
nrf_gpio_pin_set(BOARD_LED_3);
nrf_gpio_pin_set(BOARD_LED_4);

while(1)
{
    nrf_delay_ms(1000);
    nrf_gpio_pin_toggle(BOARD_LED_3);
    nrf_gpio_pin_toggle(BOARD_LED_4);
}

SDK version is nRF5_SDK_14.2.0_17b948a

Board is PCA10040(nRF52830) no custom board

SoftDevice is s132

#define LEDS_NUMBER 4

I tried the test by adding only the following sentence to main () in "examples\ble_peripheral\ble_app_uart".

bsp_board_led_invert(BSP_BOARD_LED_0);

bsp_board_led_invert(BSP_BOARD_LED_1);
bsp_board_led_invert(BSP_BOARD_LED_2);
bsp_board_led_invert(BSP_BOARD_LED_3);

The result is that only LED0 and LED1 blink

LED2 and LED3 no action

What is the LEDS_NUMBER symbol set to in your board header file? Which SDK version are you using? Are you testing this on a nRF52-DK or some custom board? If custom board, which GPIO are the LEDs connected to?

Because "Blinky" examples different work. when connect board LED 2 is turn on. But you want to turn on LED 2 and LED 3. You must change some code block.

bsp_board_led_invert (BSP_BOARD_LED_2);
bsp_board_led_invert (BSP_BOARD_LED_3);

code lines it is not enough.
