Add whitelist to ble_central_and_peripheral examples error code:12804

[shenwrt]

Add whitelist function in \ nrf5_sdk_15.2.0 _9412b96\examples\ble_central_and_peripheral\experimental\ble_app_hrs_rscs_relay, and report error 12804 (0x3204) after disconnection.

From the identities_set(PM_PEER_ID_LIST_SKIP_ALL) in BLE_ADV_EVT_PEER_ADDR_REQUEST;

        case BLE_ADV_EVT_PEER_ADDR_REQUEST:
        {
            pm_peer_data_bonding_t peer_bonding_data;

            // Only Give peer address if we have a handle to the bonded peer.
            if (m_peer_id != PM_PEER_ID_INVALID)
            {
                err_code = pm_peer_data_bonding_load(m_peer_id, &peer_bonding_data);
                if (err_code != NRF_ERROR_NOT_FOUND)
                {
                    APP_ERROR_CHECK(err_code);

					NRF_LOG_INFO("BLE_ADV_EVT_PEER_ADDR_REQUEST.");
                    identities_set(PM_PEER_ID_LIST_SKIP_ALL);

                    ble_gap_addr_t * p_peer_addr = &(peer_bonding_data.peer_ble_id.id_addr_info);

                    err_code = ble_advertising_peer_addr_reply(&m_advertising, p_peer_addr);
                    APP_ERROR_CHECK(err_code);
                }
            }
        } break; //BLE_ADV_EVT_PEER_ADDR_REQUEST

what should I do?

Thanks

Before all identities_set(), I first nrf_ble_scan_stop(); then identities_set, and finally scan_start(); there will be no error. Is there any problem with this?

Hi,

This is from the documentation of return values from sd_ble_gap_device_identities_set:

BLE_ERROR_GAP_DEVICE_IDENTITIES_IN_USE

The device identity list is in use and cannot be set or cleared.

You cannot update the identity list when it is used by scanner. You need to stop scanner and restart it as you suggest, in order to set the new list.

Best regards,
Jørgen
