Hi Marcel, i compiled correctly hcidump.<br>
<br>
So, when from my client i call i get:<br>
./l2test -n 00:10:60:29:3B:9A<br>
l2test[1349]: Can't connect: Function not implemented (38)<br>
<br>
and the dump is:<br>
<br>
HCI sniffer - Bluetooth packet analyzer ver 1.23<br>

<br>
<br>
<br>
On my server-side, i call:<br>
&gt;./l2test<br>
&gt;l2test[3280]: Waiting for connection on psm 10 ...<br>
<br>
and nothing happens.<br>
<br>
The dump of the server is:<br>
<br>
