Esphome A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

samtwilliams · July 13, 2020, 2:01pm

Hi All,

Got my first esp device, tried to flash using both the flasher tool from my windows client and also from hassio addon from my ubuntu server.

I have this device ESP32S.

On the packet the bad english says

When you “make flash”, long press BOOT button
Wait until the connecting…___ stop, then release BOOT button,

I’ve tried this and i cant get it to flash.

Anyone offer any suggestions?

This is the item i purchased fyi: esphome A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

Not sure what you are talking about when stating

flasher tool from my windows client

but when you tried to flash it from ESPHome in Hassio, did you restart ESPHome plugin once you have connected ESP32 on USB port ? If so you have well selected the ESP device that should appear in top right menu of ESPHome in Hassio ??

Yep the device shows up and i select upload but fails with the messages in the title

May you please share a full copy/paste of the compilation/transfer dialog in ESPHome ?
Picture or link of exact module you try to program ?
Did you try with an other module if you have few ones ?

I’ve tried with NodeMCU board as well.

I’ve tried holding the boot button and the EN button, but nothing works

OK, if you tried 2 boards and still get an error: try another USB cable.

DenisO · July 13, 2020, 7:36pm

Try to hold boot button, and then connect it to USB for flashing

samtwilliams · July 13, 2020, 10:14pm

Thanks tried, had Audrino port monitor on it and it’s not communicating at all, must be faulty!

DenisO · July 14, 2020, 1:19pm

Im using this one ESP32

Flashing it first time with https://esphome.io/guides/faq.html#esphome-flasher

Compile and download bin file
Hold “boot” button, connect to laptop with USB, release “boot” button
Detect ESP32 port with flasher
Flash ESP32

After that flashing over OTA forks just fine, exempt 2-5 minutes compiling some times
