Script for reading UDP
显示 更早的评论
I am trying to read UDP packets coming trough Ethernet (this is the format https://cuwb.io/docs/v3.3/software-integration/cdp-output-definition/). I can see the incoming UDP from WireShark (see below), but then I am unable to read them (I get this error: 'Cannot bind address already in use').
I am using the following code:
remote_ip = '169.254.128.7';
local_ip = '239.255.76.67';
remote_port = 49153;
local_port = 7667;
u = udp(remote_ip,remote_port,'LocalHost',local_ip,'Localport',local_port);
u.ByteOrder = 'littleEndian';
u.EnablePortSharing = 'on';
u.DatagramTerminateMode = 'off';
fopen(u);

Hi
From the error message it seems that the port is already being used by another application ( or by an earlier run of your MATLAB script) . You might need to first restart your machine to free up the port ( or kill the process that is listening on that port).
Hope this helps!
