Just an update I have found a workaround to the random connection problem if I keep "Boot" button pressed esptool.py always works (even on Win7) Thanks for reporting this, hydrabus. I have reproduced this issue on Windows 7 with a v2 core board. On Windows there is a 4ms delay between whe...

Re: A fatal error occurred: Failed to connect to ESP32: Invalid head of packet ('p')

About your question: If you put the board in download mode first using buttons does it ever fail? It seems it always works when just plugged / powered on (so yes it seems to be software bug maybe in python script of in the code injected/executed by ESP32 ...). I just want to know if the issue I des...

aggressive and annoying advertising .jpg The V1 (blue PCB) DevKitC boards have a bug with the auto-reset circuit where it doesn't work reliably. You need to hold down the "Boot" button (J3, pulls down IO0) in order to reliably enter the bootloader. V2 (black PCB, "ESP32_Core_Board_V2...
