- Mon Jul 03, 2017 10:54 am #67880 I was happy to Flash my first blink sketch to esp8266.
But how to remove it using the arduino IDE ?
I want have the original settings to control the esp with AT commands ( for testing )
Thank you

Because when uploading Arduino sketch is uploaded, the previous AT firmware is gone, completely erased ...
If you don't have such backup, you will need to find the file on Espressif site and use esptool.py to upload it according to their instructions.

- Mon Jul 03, 2017 11:41 am #67882 You can download the firmware from the Espressif website.
These instruction will show you how to re-install the standard Non-OS AT firmware.

Extra tip: get yourself a selection of ESP-boards: from plain ESP-boards to complete development-boards.
They're only a couple of bucks/euros/quid each and they makes life so much easier.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
