How to flash ESP8266-01 Firmware using Arduino

This is a demonstration video on how to flash esp8266-01 using Arduino

Link for ESP Flasher

Link for Schematics

Thanks for the help, it works . one more thing here, i used Arduino UNO and had to wire the Arduino RESET pin to GND in order for me to work.

[rssicrtical]

Works correctly. Just don't forget to connect Arduino's RESET pin to GND before you try to communicate with and/or flash the ESP-01.

[roshantv]

for those that are having problems you need to connect the reset pin to ground for 1 second and then upload

[SurajGupta]

It is showing:

Connecting...
Failed to connect

Please help

Thank you so much for the video. I spent 4 hours for flashing this crap and you solved.

Nice work! Congratulations from Brazil.

I am getting failed to connect when i clicked on download, did everything same as you told

[kirshi]

Failed to connect?
IT means either ch_pd or vcc not have enough voltage (they both need 3, 3). I connect my arduino 3, 3 pin & power module 3, 3v to plus row in breadboard and then put both ch_pd and vcc in that row, then it works (atleast in my case)(make sure the red led on esp flashing, then it's done). There is problem with header/packet or something but, you need to connect arduino RESET to Arduino GND, but before press download, disconnect that wire.

i got error
connecting ....
Failed to connect


i have made all the connection right as you have made in video

[cesarferrer]

Thank you very much, easy and without problems.

It doesn't work for me 😢 when i type AT i don't receive anything. Can someone helps me, please ?

The led on esp8266 is not lighting up... I followed exactly the same as your circuit. I saw on the internet they said the 3.3V on the arudino uno is not enough to power up the esp8266

Have tried with this and several other firmwires. It always shows flashing successful but doesn't show AT command. Please help

[omaralharran]

A million thanks for making this amazing tutorial.

[CallMeWalao]

Sorry, what's the problem, after flashing my serial monitor dont response to AT commands.

i got this error from first upload

Oh i guess i did have a problem in my board while connecting now the firmware has been flashed yet when i go IDE to type AT i get nothing ? Why

[bharatkapari]

Still AT commands not working what can be the problem

[Drakanx]

if using mega use port 0 and 1 for tx rx

[techalgorithm]

Can be do this by raspberry pi instead of aurduino?
