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

<p>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?</p>
</blockquote>
<p>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 (<code>ieee802154_radio_hal</code>).</p>

<p>When I send several messages, it seems that I have a problem with the Buffer in RX. It seems that it is not enough.</p>
</blockquote>
<p>Could you give more details? Do you have logs or some experiment to replicate this results?</p>
