Erase whitelist data in sdk9.0

[sowmya]

Hello,

I am working on S110 v8.0 softdevice and SDK9.0 and need to implement whitelist in our application. I am referring to the ble_app_hids_keyboard example project.

But how to erase the whitelist data? I couldn't find document regarding usage of whitelist.

I found ble_bondmngr.c file in SDK 5.0 for handling whitelist data to store, erase. Is there the file relating to ble_bondmngr.c in SDK 9.0?

Regards,
Sowmya

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().

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?

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().

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 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().

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.
