Sniffing COM Ports with Wireshark

asked 2021-04-08 14:11:49 +0000

Hello all,

I am working on a university project which involves analyzing IP packets from a network using a Blackfin BF537 microcontroller, which contains a minimal tcp/ip stack, and a workstation which runs Wireshark on a Linux-based OS. My question is: is it possible for Wireshark to sniff and analyze the IP packets from an UART interface? The reason for this approach is that, if i had used an Ethernet cable, it would have interfered with the network, and would have produced unwanted results.

P.S. using a COM Port sniffer would not suffice, as it only spies data.

How do the IP packets get to a UART?

If you don't want to disturb the network, then use a separate network tap and a system running Wireshark that is dedicated to that purpose.

The packets will be routed through one of the Blackfin microcontrollers through the UART interface to a PC.
