<p>Nice catch. I forgot to test these cases. BTW do you know what is the behavior of tinydtls if both PSK and ECC is enabled?</p>
<blockquote>
<p><strong>NOTE</strong>: I'm not sure, but it's seems there is another issue with ECC. The DTLS handshake is slow but stable, but the client seems to get freeze after sending the DTLS Data App record</p>

<blockquote>
<p>Ok, now I'm sure. With the ECC , the client is getting frozen. Using a dtls-echo client with ECC the performance is much different.</p>
<p>So, we have problem with DTLS Alter records, and maybe with DTLS data app after a timer expired ?</p>

<p>I'll look into this and report back later today.</p>
