Unable to auth wifi with +32 chars

[sirovermark]

Hi guys,

I can't authenticate to my AP when the WiFi password is longer than 32 characters:

I've tried to remove all the characters of the same password until ending with 32 and it works perfectly.

If it's impossible to fix this and reach the maximum length (63 characters), I think this should be documented somewhere :)

Thanks for your work!

Hi sirovermark,

Yes, you are right. The password is limited to 32 characters. Basically this is just a define in another library used: iotwebconf. There in file iotwebconfsettings.h at line 25 the following is defined:

// -- Maximal length of password used in IotWebConfig configuration.
#ifndef IOTWEBCONF_PASSWORD_LEN
# define IOTWEBCONF_PASSWORD_LEN 33
#endif

This should be resolved in the library but for now I added a define to the build to support passwords up to 63 characters.
This should fix this issue. Unfortunately this changes the configuration size so, after updating, the configuration will be lost.
Could you give it a try to see if this solves the issue? It is located in the branch bugfix_wifi_password_lenght.

Regards,

Rene

I'm unable to build it using the new code. I've cleaned everything before running it and I've tried many times:

No problems with the main one, of course :)

Thank you!

Hi sirovermark,

Was a typo. Should compile now...

[sirovermark]

Looks good @rzeldent !! :)

I have now been able to log into the WIFI using a long password.

Thank you so much for your fast response!

[rzeldent]

Nice.

I will merge it for the other users and made a bug report for the library.
prampec/IotWebConf#273

Thanks for confirming.
