Wlan will not work

[FluppFish]

Hello Michael, thank you for your cool Project! But i have a problem with my wlan credentials.

SSID: Aquarium
PASS: X{dfe5%-+xI_2%s"fd0v2}=$9{]z#S?0X@8qERT54.s6G5W>\GhB*(&$?j6=2fw

SMLReader will not login to my accesspoint and do not publish something on my mqtt server.

If i use easyer login data like SSID: Aquarium PASS: asd123ASD it will work.

Do you have a solution for that?

I tried to escape the " and the \ 
X{dfe5%-+xI_2%s\"fd0v2}=$9{]z#S?0X@8qERT54.s6G5W>\\GhB*(&$?j6=2fw

but this also will not work...

Thank you for your help... Best regards Markus

First of all, I hope that this is not you real password, you should really remove that if that's the case. Maybe you could try enabling the DEBUG Mode and look at the output?

Possibly the password is just too long for the default ESP8266 WiFi library?

[FluppFish]

For sure this is not my real wlan password! Only the special charters are the same...

The length of the password shouldn't be the problem. I thested the file from MakeMagazinDE and it worked with hard coded credentials. I only had to escape the" and the\. https://github.com/MakeMagazinDE/Node-RED-Special/blob/master/02-MQTT/mqtt_pub.ino

It could be an issue of the configuration layer (IotWebConf). May be the POST payload of the configuration form isn't decoded properly. Could you try to print the stored password as debug output at the serial line? Do you see a difference between the input and output?

As a workaround, try this: http://jorisvr.nl/wpapsk.html

I think i found the problem.

https://s20.directupload.net/images/210528/thotysh7.jpg

Max size of the html password field is 32 charters...

And now - any idea how to solve it?

[syssi]

If we assume the library is able to store more than 32 chars you could use the developer tools of your browser to manipulate this value (once). Remove the parameter or increase the maxlength. Fill the form and press submit. If 32 chars is a hard limit the POST endpoint must be checked / changed / fixed (if possible).

[mruettgers]

This issue seems to be caused by a limit in the IotWebConf library, that is used for WiFi configuration: https://github.com/prampec/IotWebConf/blob/5a8ba88a0bca5be5771ffa939a252edc021bde02/src/IotWebConf.h#L39

You might be able to override this limit this way in main.cpp:

#define IOTWEBCONF_PASSWORD_LEN 65
#include <IotWebConf.h>

[FluppFish]

Unfortunatelly it will not work.

I downloaded the latest src. Added the "#define IOTWEBCONF_PASSWORD_LEN 65" above the #include of the IotWebConf.h Used the .\d1_mini_debug\firmware.bin for program the esp8266.

Debug output is:

Could you try to print the stored password as debug output at the serial line?

Could you please explain me how to do this?

[benniju]

Well, I think it's supposed to be in the debug output where it says 'iwcWifiPassword'= that you have posted before. So my guess is that it's not stored correctly.

[syssi]

You could define IOTWEBCONF_DEBUG_PWD_TO_SERIAL: https://github.com/prampec/IotWebConf/blob/v2.3.3/src/IotWebConf.cpp#L913-L920

[FluppFish]

I tested it - there is no output. And it is still not working. Giving up for the moment - have to think in change my AP password...

[syssi]

What did you do in detail? May be there are some more steps required to enable the debug mode of the underlying library:

https://github.com/prampec/IotWebConf/blob/v2.3.3/src/IotWebConf.h#L61-L74

[mruettgers]

Side note:
In the upcoming version of SMLReader I will use https://github.com/khoih-prog/ESPAsync_WiFiManager instead of IotWebConf. Then there won't be a limit of 32 chars by default anymore.

[FluppFish]

What do you think - when the first beta will be available for your new version?

[FluppFish]

Is a known bug. https://github.com/prampec/IotWebConf/issues/62 https://github.com/prampec/IotWebConf/blob/master/doc/HackingGuide.md#compile-time-configuration

-> Issue could be closed from my side...
