webserver.py NameError: name 'stateis' isn't defined

[hairem]

I copied and pasted the code from the webserver.py into my pico w and got this error.

Traceback (most recent call last):
  File "<stdin>", line 72, in <module>
NameError: name 'stateis' isn't defined

if I comment out this line and line 76 I get a different error

Traceback (most recent call last):
  File "<stdin>", line 43, in <module>
OSError: [Errno 98] EADDRINUSE

Is there any way to fix this?

This sounds like an issue better suited to the forums where you'll probably get more help than we can offer here.

After a couple of years this is still an issue for a lot of people by the looks of a quick Google, the documentation here https://datasheets.raspberrypi.com/pico/raspberry-pi-pico-python-sdk.pdf still contains the code that will fail a lot with OSError: [Errno 98] EADDRINUSE so maybe there should be a note in the document warning people.

This question was floated in the forums;

• the suggested fix of using SO_REUSEADD does not fix the issue
• using the reset button does not fix the issue
• same in PyCharm and VScode
• running machine.reset() in the REPL does not fix the issue

It seems that the only fix is physically reconnecting the device.

@peterharperuk Any idea what might be (occasionally?) going wrong here?

Ahhh, I did a quick bit of searching and it looks like you might be running into micropython/micropython#10812 ?

Yes, using s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) (after creating the socket on line 42) should fix the EADDRINUSE issue.

The stateis issue can be fixed by adding something like stateis = "LED is ?" before the while True loop starts.
