Hi @pietrotedeschi 

> How can it is possible send and receive messages only at MAC Layer without using UDP? Please if you have a good example, provide me it.

The at86rf215 is supported using the old interface (`netdev_ieee802154`). You can send and receive frames directly using the netdev interface. You can check e.g `tests/driver_at86rf215`.

> With the previous versions of RIOT, it is not possible enable the duplicate packets recognition and so on. It is a problem related only to Openmote-b?

Unfortunately this is implemented only for GNRC. You would need to manually de-duplicate packets for now if you want to use the radio directly. We are currently working that with the new interface (`ieee802154_radio_hal`).

> When I send several messages, it seems that I have a problem with the Buffer in RX. It seems that it is not enough.

Could you give more details? Do you have logs or some experiment to replicate this results?
