BLE project

I am trying to use nrf51822 as central device and connect it to another nrf51822 acting as a peripheral device ..and i want the central to print the rssi value with respect to distance from the peripheral and i am using the example from the sdk itself named as "multilink_peripheral" but i'm still confused regarding the changes to be made in that program..

You can check out:
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s110.api.v8.0.0/group___b_l_e___g_a_p___r_s_s_i___f_i_l_t___m_s_c.html

Simply call sd_ble_gap_rssi_start() while in a connection, then you will get:

static void on_ble_evt(ble_evt_t * p_ble_evt)
{
...

    switch (p_ble_evt->header.evt_id)
    {
..
        case BLE_GAP_EVT_RSSI_CHANGED:
            rssi_value = p_ble_evt->evt.gap_evt.params.rssi_changed.rssi;
            break;
..
    }
}

ok thanks.

so i tried trying the same with nrf52840 dongle as scanner or the central device but each time i program the dongle it appears in the log as" target device closed' which makes it difficult to check the printed rssi value since the dongle is no longer connected even when it actually is connected
