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

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;
..
    }
}
