I have a standalone JavaScript (electron) application and would like to upload a file directly to my esp32 using JavaScript.

In a sense like the following solution, but not in Java, but in JavaScript: https://github.com/me-no-dev/arduino-esp32fs-plugin/blob/master/src/ESP32FS.java

Did anyone try ...

I have setup a quite simple and standard wifi client waiting for data, and wanted to test how setTimeout() would work, but i dont get this working.
This is the esp32 arduino code:

...
WiFiServer server(port);

void serverStartup(){
server.begin();
//server.setTimeout(5);
delay(1000);
Serial ...

one more question:
- what do you mean by "difficult to update the file reliably" ? What challenges would i face using mmap here?

Thanks for the very usefull comparison.

Partition api seems to be the best fit so far since it seems to be low memory cost and should cover my case with saving a few large objects (images) of same size, especially using mmap seems compelling.

2 more questions, though:

- are there any compelling ...

Thanks for the many replies - Will go down one way - either using the partition API or the file system solution.
Are there any reason to prefer one over the other?

WRT the error i was reporting before: I have tried it out without ESP_IDF using the Arduino variant on platformio. I am now setting up ...

That is an interesting option, but in my case the file is not immutable.
I will receive the data via wifi and want to write it down to flash.

What would be a suitable option here?

I have tried out the wear-levelling example at
https://github.com/espressif/esp-idf/tree/master/examples/storage/wear_levelling
but i get:

E (321) vfs_fat_spiflash: Failed to find FATFS partition (type='data', subtype='fat', partition_label='storage'). Check the partition table.
E (322) example ...

Thanks a lot for your fast reply and your pointers - from what you are saying it seems that also other flash access library (like the partition_table api) will also hit the same boundary as NVS. Right?

So it seems that SPIFFS might be the only well-documented way of handling with larger files on ...

Hi,

I am looking for the best way to store a larger image object (around 10k) on the internal flash. I tried to store it as binary using NVS, since NVS is the best described way in the documentation (including examples). But it seems i am hitting a 4k boundary here (along with some guru meditation ...
