Console showing 193391][E][vfs_api.cpp:105] open(): /littlefs/index.html does not exist, no permits for creation

It's happening some random reboots, and in the console every page refresh the message below appears.

193391][E][vfs_api.cpp:105] open(): /littlefs/index.html does not exist, no permits for creation

These messages are mostly OK - I'll breakdown what's happening though:

193391][E][vfs_api.cpp:105] open(): /littlefs/index.html does not exist, no permits for creation
     - this message is fine and can be ignored

[195080][E][vfs_api.cpp:105] open(): /littlefs/assets/i18n/en-US.json.gz does not exist, no permits for creation
[195190][E][vfs_api.cpp:105] open(): /littlefs/assets/i18n/pt-BR.json.gz does not exist, no permits for creation
     - this message states that it cannot find certain translations

[ERROR] - Failed to get time from Worldtime API
     - this is likely the problem. When this message shows up, it means the remote NTP server, "worldtime" has rate limited your winder; it isn't returning the time.

I'm in the process of adding some more customizations that allows you to manually set the winder's internal clock. You can see that here: #71

I hope to get this merged soon, and that should solve your timing issue...I hope.

Is is possible to set a locally ntp server? Ex my home ntp server?
Any other clue for the LED? I'm trying to setup mine but is not working. When I plug the ground wire from the ESP32 to the OLED the ESP32 just freeze and reboot and stay freezed until I disconet the ground wire. If I use and external ground wire from an external power supply, it's not working too.

That's an interesting idea actually 🤔 , unfortunately at this moment there isn't.

Hmm, are you sure all of the pinouts are set correctly in the code?

Did you follow this wiring diagram?

• https://github.com/mwood77/winderoo/blob/main/docs/wiring-diagram.md#winderoo-with-oled-screen

Do you know if these parameters are correct for your OLED screen?

  if (!display.begin(SSD1306_SWITCHCAPVCC, 0x3C))

Specifically in the last point 0x3C is an address. Are you sure that's compatible with yours too?
