低连接时进行领域对象服务器同步

Question

我有一个 Realm 对象服务器，并尝试与 Android 设备同步数据，例如：

SyncCredentials syncCred = SyncCredentials
            .usernamePassword(username, password, false);
SyncUser.loginAsync(syncCred, url, new SyncUser.Callback() {
        @Override
        public void onSuccess(SyncUser user) {
        ...some code...
        }
        @Override
        public void onError(ObjectServerError error) {}

它适用于wi-fi但是在互联网连接较低的情况下（例如为模拟器设置GSM网络类型），我收到错误（onError (ObjectServerError error)调用）：

是否可以通过低互联网连接同步数据？
