Or something similar to have a reference...

I know, it's been a while since the question was asked, but I've just happened to add user data service to my project.

static ble_gatts_char_handles_t fname_handles;
static ble_gatts_char_handles_t lname_handles;
uint16_t uds_handle;

static void add_userdata_service (void)
{
 ret_code_t err_code;
 ble_uuid_t ble_uuid;

 /* Add User Data Service */

 BLE_UUID_BLE_ASSIGN (ble_uuid, 0x181C);

 err_code = sd_ble_gatts_service_add (BLE_GATTS_SRVC_TYPE_PRIMARY,
 &ble_uuid,
 &uds_handle);
 APP_ERROR_CHECK (err_code);

 /* Add First Name characteristic */

 char * fname = "Vadim";
 ble_add_char_params_t fname_char_params = {
 .uuid = 0x2A8A,
 .max_len = strlen (fname),
 .init_len = strlen (fname),
 .p_init_value = (uint8_t *) fname,
 .char_props.read = 1u,
 .read_access = SEC_OPEN
 };

 err_code = characteristic_add (uds_handle,
 &fname_char_params,
 &fname_handles);
 APP_ERROR_CHECK (err_code);

 /* Add Last Name characteristic */

 char * lname = "Barshaw";
 ble_add_char_params_t lname_char_params = {
 .uuid = 0x2A90,
 .max_len = strlen (lname),
 .init_len = strlen (lname),
 .p_init_value = (uint8_t *) lname,
 .char_props.read = 1u,
 .read_access = SEC_OPEN
 };

 err_code = characteristic_add (uds_handle,
 &lname_char_params,
 &lname_handles);
 APP_ERROR_CHECK (err_code);
}

Hope this helps.
