Thank you

Maybe i have not good declare my question. It is for the exemple "ble-app Multilink central" I need that the CENTRAL-CONNECTED-LED BSP_BOARD_LED_1, toggle on "ble-app Multilink central" when case BLE_GAP_EVT_CONNECTED. And not toggle when case BLE_GAP_EVT_DISCONNECTED

When possible please as exemple for BSP und exemple for nrf_gpio Thnak you very much! MC

you should initialize your LED like below

static void leds_init(void)

{
   nrf_gpio_cfg_output(CENTRAL_CONNECTED_LED);
   nrf_gpio_pin_set(CENTRAL_CONNECTED_LED); // this will switch OFF led on pca10028

}

Then when you get connected and disconnected events then you should set the LED state again in the on_ble_evt() function in the SDK ble_peripheral examples (assuming that your device is peripheral)

static void on_ble_evt(ble_evt_t * p_ble_evt)
{
    uint32_t err_code;

    switch (p_ble_evt->header.evt_id)
    {
        case BLE_GAP_EVT_CONNECTED:
            NRF_LOG_INFO("Connected\r\n");
//            err_code = bsp_indication_set(BSP_INDICATE_CONNECTED);
//            APP_ERROR_CHECK(err_code);
               nrf_gpio_pin_clear(CENTRAL_CONNECTED_LED); // this will turn on the LED on pca10028
            m_conn_handle = p_ble_evt->evt.gap_evt.conn_handle;
            break; // BLE_GAP_EVT_CONNECTED

        case BLE_GAP_EVT_DISCONNECTED:
            NRF_LOG_INFO("Disconnected\r\n");

//            err_code = bsp_indication_set(BSP_INDICATE_ALERT_OFF);
//            APP_ERROR_CHECK(err_code);
            nrf_gpio_pin_set(CENTRAL_CONNECTED_LED); // this will turn OFF the LED on pca10028
            m_conn_handle = BLE_CONN_HANDLE_INVALID;

Hello Aryan i have do it with nrf_gpio.. like this:

    #define CENTRAL_CONNECTED_LED  22

static void leds_init(void)

{
   nrf_gpio_cfg_output(CENTRAL_CONNECTED_LED);
   nrf_gpio_pin_clear(CENTRAL_CONNECTED_LED);
   while(1)
   {
       nrf_gpio_pin_toggle(CENTRAL_CONNECTED_LED);
       nrf_delay_ms(1000);
   }
}

The led now blink evry time, but i need that the led blink only when the periheral is connected.

Sorry about my english. is possible that you send me a exemple for BSP und exemple for nrf_gpio. please with exactly where i must write the code.

thank you very much mc

do you want to use BSP library for this? or is it ok if you can just use the nrf_gpio_pin_write API and control the LED_1 which is connected to pin number 21
