Reset all settings - BTT E3 RRF V1.1

[toreandreas]

Hello.
I have managed to make a mistake. I have changed the password on WIFI in webui, and now I can no longer enter. Both in AP and in client mode. This is because I was unable to connect to my network. I think #define MAX_PASSWORD_LENGTH was set to 16 (which is too low). And then I have appostrophe in the password, which I know has been problematic before. Can I change something in firmware that deletes / resets webui, or is there another solution?
The card is as mentioned in the heading a BIGTREETECH E3 RRF V1.1. Software was downloaded here on 28.07.2021.
Thank you in advance.

What Firmware version are you using ? 2x or 3.0 ?
the command to reset setting is [ESP444]RESET

[toreandreas]

ESP3D-2.1.x (https://github.com/luc-github/ESP3D).
I followed https://www.youtube.com/watch?v=7J9vFdrF9kQ, but used higher baud rate, 250,000.
I'm new to 3D printing, and even newer in ESP3D... Where to enter the command [ESP444] RESET? (The terminal for octopi?). Does anything need to be changed in any firmware first?

[luc-github]

well on 2.1 it won't work, because even for serial it will ask for admin password - the only solution is to erase full flash , then reflash

[luc-github]

Ok I just watched the video - I did not know the bootlader supported ESP3D.BIN file on SD to flash the ESP (sorry I do not know this board ....)
So my suggestion :
1 - disable Authentication in ESP3D then flash like you did
2 - modify the admin and user passwords in webUI
3 - flash again by enabling authentication

I have a doubt which password did you changed ?

[toreandreas]

1 - Will this stop the ESP3D from entering webui?

I changed password in webui, for AP mode, and Client mode.

I am not at home now, so I can not test yet.

[luc-github]

ok the mention of

#define MAX_PASSWORD_LENGTH was set to 16

confused me, so you do not enabled authentication - right ?

In that case you can send any serial commands to reset all or just setup wifi : https://raw.githubusercontent.com/wiki/luc-github/ESP3D/docs/Commands2_1.txt

to do this just use the serial of your printer and use the M118 P0

but as I am not sure Marlin will forward answer from ESP3D serial, so better to do full reset

M118 P0 [ESP444]RESET
M118 P0 [ESP444]RESTART

But after looking at video, if you followed it, seems the default values are changed in code, so before, you need to put back the original value for password : 12345678 , like this you will only modify in webui and a reset will always allow you to have a working AP

or you can try first

• Change AP Password
  [ESP106]12345678
  they see if you can connect in AP mode with password 12345678, they change others settings after

First, it was not the #define #define MAX_PASSWORD_LENGTH, it was MAX_LOCAL_PASSWORD_LENGTH. So there was nothing wrong, except my memory.

Flashed with ESP3D.bin (Without any changes in config.h, or other files.)

Tried [ESP444] RESET in octopi / terminal:
Send: [ESP444]RESET
Recv: echo:Unknown command: "[ESP444]RESET"
Recv: ok
Tried logging in with password 12345678, no success.

Tried M118 P0 [ESP444]RESET, and M118 P0 [ESP444]RESTART (also in octopi/terminal):
Send: M118 P0 [ESP444]RESET
Recv: [ESP444]RESET
Recv: ok
[...]
Send: M118 P0 [ESP444]RESTART
Recv: [ESP444]RESTART
Recv: ok
Tried logging in with password 12345678, Success.
I have to disconnect from the internet with this PC, but will be back.

[toreandreas]

Success confirmed.
I think M118 P0 [ESP444] RESET, and M118 P0 [ESP444] RESTART were the fixed .

Everything works, but not apostrophe in the WIFI password. I noticed one thing. About my password is: abcdef'ghijklmn. I wrote this in the wizard. When I later checked up on this it just said: abcdef. It is possible that I use is not an apostrophe, but another sign.
I have no idea where I can check this out, here may not be the right place to ask.
Anyway, thanks for all the help.

Is it possible to enter (or otherwise) enter passwords like Hexadecimal?
See http://jorisvr.nl/wpapsk.html

only passphrase is supported
the password of 32 chars has in theory no limitation -
if it has it can be :
1 - a limitation of esp core (e.g.: before space where not working, it was fixed after a while)
2 - a bug in webUI with some char is not properly encoded - to solve this I need:
a - a confirmation that M118 P0 [ESP106]xxx'xxxx does not work and allow you to connect
b - a clear version of what password is not working
Note: password is not displayed in theory once key in- so I do not understand you can see it
