Yes thank you for the reply. I am able to delete whitelist data with dm_device_delete_all() function and it is working.

That is probable because of this case in ble_advertising_on_ble_evt():

case BLE_GAP_EVT_DISCONNECTED:
{
    uint32_t err_code;
    m_whitelist_temporarily_disabled = false;

    if (p_ble_evt->evt.gap_evt.conn_handle == current_slave_link_conn_handle)
    {
       err_code = ble_advertising_start(BLE_ADV_MODE_DIRECTED);
       if ((err_code != NRF_SUCCESS) && (m_error_handler != NULL))
       {
           m_error_handler(err_code);
       }
    }
    break;
}

On disconnect it will enable the whitelist and start directed advertising.

Yes in some thread I found the soultion to use ble_advertising_restart_without_whitelist() but after disconnect from 2nd device, will it be able to connect to the first or second device? I found that it will be able to connect to the first device not the second.

I believe I have misunderstood your problem. Maybe you can just call ble_advertising_restart_without_whitelist() on button press? The bond to the first device will not be deleted, but the second device should be able to connect.

Can you please clarify me that ble_app_hids_keyboard example allows us to erase the whitelist or is it an example only to store the bonded device ? Edit: I want the board to be connected to single master(mobile) and if user wishes to change the phone then using the button press I should be able to erase the whitelist data. This is my requirement and the application will not advertise after disconnection.

I believe you are mixing up directed advertising with advertising with whitelist. To disable directed advertising change the ble_adv_modes_config_t struct in advertising_init().

I followed the way suggested by you but it is not working. I added dm_device_delete_all() before the code snippet in on_adv_evt callback for BLE_ADV_EVT_PEER_ADDR_REQUEST case:

            // Only Give peer address if we have a handle to the bonded peer.
        if(m_bonded_peer_handle.appl_id != DM_INVALID_ID)
        {
                        
            err_code = dm_peer_addr_get(&m_bonded_peer_handle, &peer_address);
            APP_ERROR_CHECK(err_code);

            err_code = ble_advertising_peer_addr_reply(&peer_address);
            APP_ERROR_CHECK(err_code);
            
        }

After this the address stored is cleared but still I am not able to connect from a 2nd device i.e., 1st I am connecting through MCP on PC and for the 2nd time I am trying to connect using MCP on android.

I think you are correct :) If you delete a bond in the device manager the address/IRK of the bond will not be included in the whitelist created with dm_whitelist_create().

Yes I am testing with unmodified example and bonding is enabled in that example. Now I am getting a question that can the bond manager and whitelist be used together?

Update: Ok I got it. If we delete bond information, whitelist address stored also will be erased. I'm I correct?

If you are using the unmodified example you are using the device manager. The whitelist is created by calling dm_whitelist_create(). This created a whitelist with the addresses and IRKs of the bonds that currently exist.

So to "erase" whitelist data either don't use dm_whitelist_create() or delete bonds with dm_device_delete() or dm_device_delete_all() before you create the whitelist with dm_whitelist_create().
