How to read Value if Service 128bit UUID is completely different from Characteristics 128 bit UUID ?

[Vipul2988]

I am able to pair a peripheral device using advertising 16bit UUID to the Central Device(nRF52840-DK board).

Also I am able to read the Battery level service and Device  information service using bas_c_init() and dis_c_inti(). That' Good.

Now device has Some other Custom Primary services with different 128bit service UUID & 128bit Characteristics UUID. See Image Below 

 

To read such values from Unknown Characteristics which function we need to use ? 

I am using nRF52840-DK with nRF5_SDK_17.0.2 and S140

It looks like it should be something like this (note the comment that you must also update ble_lbs_c_t in this case):

uint32_t ble_lbs_c_init(ble_lbs_c_t * p_ble_lbs_c, ble_lbs_c_init_t * p_ble_lbs_c_init)
{
    uint32_t      err_code;

    ble_uuid_t    lbs_uuid;
    ble_uuid128_t lbs_base_uuid = {PRESS_SER_UUID_BASE};
    ble_uuid_t    lbs_char_uuid;
    ble_uuid128_t lbs_char_base_uuid = {PRESS_CHAR_UUID_BASE};

    VERIFY_PARAM_NOT_NULL(p_ble_lbs_c);
    VERIFY_PARAM_NOT_NULL(p_ble_lbs_c_init);
    VERIFY_PARAM_NOT_NULL(p_ble_lbs_c_init->evt_handler);

    p_ble_lbs_c->peer_lbs_db.button_cccd_handle = BLE_GATT_HANDLE_INVALID;
    p_ble_lbs_c->peer_lbs_db.button_handle      = BLE_GATT_HANDLE_INVALID;
    p_ble_lbs_c->peer_lbs_db.led_handle         = BLE_GATT_HANDLE_INVALID;
    p_ble_lbs_c->conn_handle                    = BLE_CONN_HANDLE_INVALID;
    p_ble_lbs_c->evt_handler                    = p_ble_lbs_c_init->evt_handler;

    err_code = sd_ble_uuid_vs_add(&lbs_base_uuid, &p_ble_lbs_c->uuid_type);

    if (err_code != NRF_SUCCESS)
    {
        return err_code;
    }
    VERIFY_SUCCESS(err_code);

    err_code = sd_ble_uuid_vs_add(&lbs_char_base_uuid, &p_ble_lbs_c->uuid_type_char); // You need to add uuid_type_char in the ble_lbs_c_t so that it exists

    if (err_code != NRF_SUCCESS)
    {
        return err_code;
    }
    VERIFY_SUCCESS(err_code);

    lbs_uuid.type = p_ble_lbs_c->uuid_type;
    lbs_uuid.uuid = LBS_UUID_SERVICE;

    lbs_char_uuid.type = p_ble_lbs_c->uuid_type_char;
    lbs_char_uuid.uuid = PRESS_CHAR_UUID;

    return ble_db_discovery_evt_register(&lbs_uuid);
    return ble_db_discovery_evt_register(&lbs_char_uuid);
}
