Thanks for showing the problem. Got a solution for it ;) and luckily it works ;)

static void sleep_mode_enter(void)
{
    APP_ERROR_CHECK(bsp_indication_set(BSP_INDICATE_IDLE));
    
    /* Disable all timers and buttons. */
    bsp_buttons_disable();
    app_timer_stop_all();

    /* Prepare wakeup buttons. */
    APP_ERROR_CHECK(bsp_btn_ble_sleep_mode_prepare());

    /* Go to system-off mode (this function will not return; wakeup will cause a reset). */
    APP_ERROR_CHECK(sd_power_system_off());
}

Best regards,

Duy

In those two examples, all buttons with sense enabled will be able to wake up the chip in the bsp_init(BSP_INIT_BUTTONS). The documentation does not reflect the detail. Nice catch! Thanks.

Hello Amanda,
