D1 mini nodeMcu ESP8266MOD 12-F: esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header (ESPTOOL-110)

[jordivandijk]

I'm kinda new to this. I have some arduinos and decided to try this D1 mini. on 1 of my computers the chip did not even show up no matter what i did (installing drivers, re-installing arduino ide / pyhton and the esp8266 comunitie lib). On my onther pc it shows up but i get this message:

esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header

i've tried multiple things such as comnecting pin d4 to ground while uploading. but it just wont work.

Windows 10

Python version 3.8

Can run python -V to check this.

Hi @jordivandijk,

Are you sure the serial port COM1 is correct?

The ESP8266 doesn't seem to be responding. This may be because the hardware is not working propertly at all, or it may be because there is some problem with resetting into the correct mode.

i've tried multiple things such as comnecting pin d4 to ground while uploading. but it just wont work.

I think for WeMOS D1 Mini the pin to ground is D3. (Normally it's referred to as GPIO0, but WeMos use their own pin numbering scheme - may need to check whatever docs came with your board)

If you have GPIO3 (aka D3) grounded, and nothing else connected to the D1 Mini at all (including removing it from any breadboard), try pressing Upload in Arduino IDE and then quickly pressing and releasing the Reset button on the module, and see if it can upload this way.

If that doesn't work, suggest going through the other items here: https://github.com/espressif/esptool/#bootloader-wont-respond

... and if nothing works, I'm afraid you may have faulty hardware.
