I know we cannot transfer data between android and iOS devices through bluetooth. But, can the iOS device scan and "see" the android bluetooth device (get the list with name of bluetooth), in both cases normal bluetooth and BLE?
An app running on iOS cannot discover any Bluetooth 2.1/3.0 devices (excluding MFi devices for which the app is registered, which does not apply to an Android device).
If the Android device is advertising BLE/BT4.0 service(s) then an iOS app can use Core Bluetooth to discover these service(s).
