ESP32 Forum

I'm using an ESP32 dev board that requires pressing the boot button to flash it. The compile time in the Arduino IDE takes almost a minute, so I have to sit and watch the progress so I can press the boot button at the appropriate time.

It would be really nice if I could hear a beep when it's ready for me to press it.

I'm using Windows 7, and have Python installed and use it all the time. I tried modifying this esptool.py:

C:\Users\[username]\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.5.2\tools\esptool\esptool.py

But apparently it's not using that version since my changes have no effect. I'm guessing it's using the packaged esptool.exe at C:\Users\[username]\AppData\Local\Arduino15\packages\esp32\tools\esptool_py\2.6.1

Is there some way to force it to use the .py version?

Or some other clever way to make the IDE beep when it's ready to flash?

Use USB serial konverter with rx/tx rts, dtr output. Then esptool automatic switch flash prg mode to module.

Thanks for that, very interesting.

I'm still hoping to be able to use a custom version of esptool.py (instead of the packaged exe)... Or I guess could package it with PyInstaller?

Or isn't there some way to edit the command that the Arduino IDE sends to esptool?
