Hello,<br>
<br>
I am new to ndnSIM and the answer to my question might be simple but
I have been trying for the last couple of hours with no success. I
am using this code to connect the TransmittedContentObjects to
function ContentTransmitted. This function only prints "sent".<br>
<br>
Config::Connect
("/NodeList/*/$ns3::ndn::Producer/TransmittedContentObjects",
MakeCallback (ContentTransmitted));<br>
<br>
However, this does not seem to work since "sent" is not printed. My
ndnSIM setup is as the instructions on this page

Thanks for your help,<br>
