Hello all, can anyone recommend some type of sniffer to monitor packets
coming and going from our devices? Our wireless carrier is showing that our
devices have a much higher data usage than we believe. I would like to be
able to run something on our PPC to see just how much data is being
transmitted back and forth.
 
You don't want a separate sniffer! To sniff cellular packets would take a
*very* specific piece of equipment and it would snow you under information.
I suppose that you can probably rent one, if it's that valuable to you.

In the device SDK, look up the IPHelper functions, particularly those for
fetching the number of TCP, IP, UDP, etc. packets sent and received. Those
might allow you to figure out what part of your system in sending or
receiving the extra data. Don't forget that, if you transfer a Web page,
it's not the size of the page alone that counts; there is header information
on every single packet, too. If you Google on "windows ce" network sniffer,
you'll find some other things that might help you write a program to figure
out where the bytes are going.
