How to turn on 4 LEDs in BLE at nrf52832?

[alex kim]

Hi, Everyone
How to turn on 4 LEDs in BLE ?
I am testing ble_app_uart on nrf52832 (softdevice s132).
Try to blink the four LEDs on the board do.
I have added to main()
bsp_board_led_invert (BSP_BOARD_LED_2);
bsp_board_led_invert (BSP_BOARD_LED_3);
LED 2 and 3 don't turn on

Can somebody guide me what could be the problem?

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.

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?

[alex kim]

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
