404 on Wifi Setup

[henfri]

Hello,

unfortunately, I get a 404 Error when connecting to 192.168.4.1 (of course I have connected to the right WiFi before).

The only odd thing in the log is the [E][Preferences.cpp:49] begin(): nvs_open failed: NOT_FOUND.
But I do not think, this is related, is it?

Are you still trying to use a ESP8266? Preferences (storing data in NVS) is a feature of ESP32 and not available on the ESP8266 and thereby the complete storage layer has to be ported to something available on the ESP8266.

[henfri]

No, I am using ESP32.
@ALL: can you please check, if you also have the [E][Preferences.cpp:49] begin(): nvs_open failed: NOT_FOUND. to rule out that this is the issue?

[henfri]

I have now checked with your original code, except for my changes in platformio.ini

[env:esp32doit-devkit-v1]
platform = [email protected]      # @3.5.0 #otherwise Update.h is missing. See https://community.platformio.org/t/update-espressif-32-version-4-1-0-leads-to-error-collect2-exe-error-ld-returned-1-exit-status/27742/3 
                                  # Other fix is to use a different version of the Asyncwebserver (https://github.com/khoih-prog/ESPAsyncWebServer/archive/refs/heads/master.zip.)

I get the [E][Preferences.cpp:49] begin(): nvs_open failed: NOT_FOUND also here.

And also, I get the 404. So, it is not related to my changes.

Hello,

I got it working by flashing your binary. That worked so far, that I got the wifi configuration page (I did not configure).
Then, I flashed my binary again and it worked as well.

Maybe, there was something wrong with my partitioning/bootloader etc.

Greetings,
Hendrik

Hm, seems there was a problem building and uploading your SPIFFS image, that would explain the 404 error because the html files were not found. However great it works for you now!

[henfri]

Hello,

any idea how to improve this? After erasing the flash, I always have to first to flash your binary before I can flash the pio code.
Is maybe the building and flashing of the SPIFFS image missing in the PIO chain?
I am struggling with the same issue with the ESP8266 port now.

Greetings,
Hendrik

[henfri]

Ah... Maybe it is user error...
There is a task "build filesystem" and "upload filesystem". I suppose, I would have to run that...?

[frickelzeugs]

Yes 😉
