I have a ESP32 WiFi module sending millisecond values ( unsigned long ) via UDP on port 52791.
I am able to read the same on a iPhone based App with no issues.
But the LabVIEW code as attached refuses to read anything and read function returns Error 56.
Not sure what is wrong. ( The laptop running the code is on the same network as the ESP32 module.
Solved! Go to Solution.

Hi Raghunathan,
Can you check that your firewall is not blocking this port on your computer? Can you try different ports and see if that helps?
Best,

I noticed that the UDP reception was OK on another new PC.
In my laptop there was a disabled Windows Defender and also a full time Kaspersky Anti virus. In the process even private networks were being firewalled. Once this was corrected the problem was solved.
Thanks for the suggestion !!
