OSError: [Errno 22] EINVAL, socket.SOCK_RAW

[mercan001]

Hi,
I have little experience with micropython, i'm working with thonny and writing a code but receive error report. What is wrong?

>>> import socket
>>> socket.socket(socket.AF_INET,socket.SOCK_RAW,0)
Traceback (most recent call last):

File "<stdin>", line 1, in <module>

OSError: [Errno 22] EINVAL

Have you seen the tutorial at https://docs.micropython.org/en/latest/ ... k_tcp.html

What sort of server are you trying to connect to?

[mercan001]

Yes, I have seen. I don't want to connect to the server. If i wanted it i write different code.

Unfortunately SOCK_RAW is not supported -- see https://github.com/micropython/micropyt ... wip.c#L795

I don't know the history, especially why the implementation is partially commented out (perhaps it wasn't deemed important enough, so it's disabled to keep the code size small?).

Thank you for your answers, but this is bad news.
Whereas I have to send raw code to net! I wonder if I can do it in a different way? Is there another way?

I guess you could try building the firmware yourself and enable those lines? Search modlwip.c for any line containing the word "raw".

[mercan001]

I do not know to build firmware myself.

If you're interested in learning more about the process, the build instructions are here: https://github.com/micropython/micropyt ... ts/esp8266

These linux and macOS operations i don't know linux.

I guess i will learn another programming language for esp. It will be the fourth language.
