Updating Espruino Wifi Firmware does not work

Hello!

For a while I have been trying to update the Wifi Firmware of my Espruino Wifi, but it does not work. Currently the Espruino Wifi itself is running on Firmware Version 2v13. I can not determine the current version of the Wifi Module. Switching the used USB cable did not help either (as suggested in the only other thread I could find for this topic).
My Browser is Chromium 104 (with experimental features enabled) on macOS 12.4.

When using the Check firmware version in the settings page of the IDE it always fails with the error message

The ESP8266 did not respond to the version request`

Looking into the browsers dev tools console reveals the last commands:

Splitting for Ctrl-C, delay 250
Splitting for Ctrl-C, delay 250
Uncaught (in promise) DOMException: The device has been lost.

The Update WiFi module Firmware (Beta) feature does not work as well. The initial dialog shows:

This option will update your Espruino WiFi's ESP8266 WiFi module to the latest version (ESP8266_AT_1_5_4_8M). This will take several minutes, and should not be stopped halfway. Espruino WiFi should not be in bootloader mode when you connect.

undefined

When proceeding the following text is shown in the console:

Thanks for your help!

Hi there,

sorry to hear you are having trouble updating the Espruino WiFi.

You could try upgrading the firmware using the stm32loader.py with a Terminal Window:

Hope this will work for you!

Hi,

Is the Espruino WiFi connected to anything? Or is it just 'as it came' with nothing attached to the pins?

Also, are you able to use the Wifi in the Espruino WiFi at all at the moment, using normal JS code?

It might be that you have some code running on the Espruino WiFi that is interfering and causing the flashing to fail I guess? You could try running require("Storage").eraseAll() and then reset() and see if that helps?
