This is an excellent example of the ESP Web Tools library in action to flash ESP devices. Thanks!

Could you please add a license to indicate if the code is available for re-use in other projects?

With my ESP32 S3 based board I keep getting the error that the boot button needs to be pressed. But flashing the firmware via VScode + Platform.io works without problems (without pressing any buttons). Any idea how to adapt the web installer config to make this work? also asking for my own open source fork of the web installer.

Hello,
since the SR fork got a new release and is now up to Wled version 13.2 could you replace the 13b6 binary for the new one?

Hello, just tested the web installer with release 0.14.2 on Lolin C3 mini
The installer does its thing but the board does not boot wled afterwards.
The serial writes these messages:

E (286) esp_core_dump_flash: No core dump partition found!
Ada
E (4856) phy_init: load_cal_data_from_nvs_handle: calibration data MAC check failed: expected 68:b6:b3:75:79:60, found a0:76:4e:43:be:70

FYI tasmota web installer works correctly on this board

I cannot flash wled to a wemos S2 mini with the web installer (esp8266 and esp32 are ok)
I have also tried the alternative bootloader without success.
I have been holding the board in bootloader mode pressing the boot button during reset.

I have also tried flashing the firmware with esptool without success for the esp32 s2 model,
the only instructions I could find apply to the esp32 (non s2).

The only way I could load the firmware is with this convoluted procedure
Aircoookie/WLED#3706 (comment)

Anyway having flashed with this method I cannot upgrade wled from the web interface as would normally do because the update fails. (so I would need to use the tasmota trick again)

best regards

Hello, I am new to all this so please excuse my cluelessness.

I was trying to flash WLED on my new esp32 dev board. I bought it from waveshare and it has an ESP32-S3-WROOM-1 if that makes a difference.

The problem is that when the installation finishes and I click next I get thrown back to the logs/installation menu instead of the configure WiFi menu. After some searching I found an error message in the console of the browser saying the following:

Improv initialization failed. Error: Improv Wi-Fi Serial not detected
at install-dialog-19322187.js:424:1210

If anyone has a clue about what could be the issue please write it below.

Thanks in advance :)
