Unable to connect to wifi #94

Closed Kev0123 closed 2 months ago

Kev0123 commented 2 months ago

I am unable to connect to wifi, its a 40 digit password with serveral special characters. These are the ones contained: {($<~%}_! at least one of them is causing an issue with connection.

Hi, how familiar are you with ESP and Arduino and can you confirm that this password generally works on an ESP with Arduino? So the problem only exists with this project and it works in other ESP projects with Arduino? I'll have to test it myself. My WiFi password is not that complex. Maybe it is a general issue with the WiFi Class of Arduino.

The issue is not affecting e.g. the WLED project.

ok, I will test it.

Id did some tests and found the reason for that. It is not related to WiFi function itself. It is a problem of handling the user input from my side. I use snprintf to copy the user input from the webUI to the config structure. And in printf function the % is a special formatting character. If you have a % in the string, it will be removed.

It's a bit unlucky how I currently use the function. Will be fixed with the next release. Thanks for reporting.
