pysoem on windows 10 problem - will appreciate help about pysoem HOT 9 CLOSED

well, after some deep diving, i think i have found the problem.
you should use npcap and not win10pcap...

from pysoem.

I have the same problem (Windows 10, could not open with pcap, pysoem.find_adapters() finds ID, Wireshark works and can access interface), although I have installed npcap 1.50. Any suggestions?

from pysoem.

In my case I needet to input ID in this format: '\Device\NPF_{A36B0DE6-FA8F-4113-AC4F-EEFF9E02CEC3}'

from pysoem.

have you solved the problem?

Weird, on Win 11 we had to do this:

'\Device\NPF_{A36B0DE6-FA8F-4113-AC4F-EEFF9E02CEC3}'

Hello,
I have same problem except I am using Realtek USB GbE Family Controller.
I am using the notation: \Device\NPF_{7A0F6319-EC6D-4EF5-ADC5-52F691B8F63D}
with Winpcap installed.

could not open interface \Device\NPF_{7A0F6319-EC6D-4EF5-ADC5-52F691B8F63D}
File "C:\basic_example.py", line 426, in run
self.master.open(self.ifname)
File "C:\basic_example.py", line 564, in
BasicExample('\Device\NPF{7A0F6319-EC6D-4EF5-ADC5-52F691B8F63D}').run()
ConnectionError: could not open interface \Device\NPF{7A0F6319-EC6D-4EF5-ADC5-52F691B8F63D}

What can I do to solve this issue?

from pysoem.

Hello, it seems the ncap is not properly installed with Windows 10 by selecting the option
Install Npcap in WinPcap API-compatible Mode (WinPcap will be uninstalled)

from pysoem.

Sorry for adding a comment to a closed issue.
Still, I would like to share what worked for me on Windows 10.

master.open('\\Device\\NPF_{24D8A70B-00A0-4643-81DE-C1D2DF72396D}')

The double backslash \\ is the trick.

Also you can try this
master.open(r'\Device\NPF_{B520D7ED-4AC0-48F9-9574-09C0696C3DA4}')
my mistake is that I didn't put "r" in front of the quotes with the interface name to read the slashes correctly
