I just setting next one:
const led_sb_init_params_t led_sb_init_param = {
.active_high = false,
.duty_cycle_max = 0xFF,
.duty_cycle_min = 0,
.duty_cycle_step = 0xFF,
.off_time_ticks = APP_TIMER_TICKS(0),
.on_time_ticks = APP_TIMER_TICKS(0),
.leds_pin_bm = (1 << SW_LED_RED_PIN) | (1 << SW_LED_GREEN_PIN) | (1 << SW_LED_BLUE_PIN),
.p_leds_port = NRF_GPIO,
};
And got almost led light, but with little blink. Can someone help me to know is it real?
