For those experiencing upload Fatal error problem. After everything is assembled, put a ground switch on the ESP8266 reset pin. Power up the arduino nano and esp8266. Press reset pin for half a sec. Then upload program. GPIO-2 DOES NOT need to be 3.3V HIGH.
Sorry, didnt get what you mean by "press the pin". Is it like "connect and disconnect right away"? Also, as per GPIO-2 - should it be LOW while i'm uploading the code? Thanks!
Tried this today. For me it never works when i "press reset pin for half a sec". I could only upload code when Reset was connected to the GND from the moment before powering up the arduino and ESP8266 till the end of uploading. Otherwise it always fails with uploading. Maybe this is because I'm using Arduino Uno, not Nano?
Basically you are using the ftdi chip of the nano to program the esp. That will work for sure. I find it easier to use a 3v3 ftdi adaptor, but to each its own
HI! thanks so much for this video, worked a treat for me after many hours of failure. I wired the ESP8266 as per your instructions. However I found some additional things to look out for namely the download settings, which I matched to those seen on your pc, and also ensured that I was using 2.3.0 version of the ESP8266 library.
Finally solved Even if your jumper cables are slightly loose noise occurs ,so i soldred the connections on a pref board and put female headers on it to program esp 8266 this worked for me try it out....
hi, I replicated your example and the IDE finished uploading the program but I do not get any serial prints. I added a reset button and removed the programming ground to GPIO0. then I reset the board and got (at 74880 baud rate) a message that the ESP8266 is still in boot mode (3,6). what im doing wrong?
Surprisingly, I saw lots of recipes for ESP8266 where they say "connect GND and Reset by a wire". On the other hand, for programming ATTiny they say "connect GND and Reset by a 10 uF capacitor". Do you know why? Maybe, not a wire, but a capacitor should be used for ESP8266 too? I tried the scheme proposed in this video (except that i used a 5v-3.3v converter to feed ESP8266), and I keep getting tons of errors while deploying the program to ESP. I have to unplug USB and plug it back again, and then it works - about 1 success out of 15-20 attempts.
It worked! Thanks man ^_^ Btw, I used Arduino UNO and i used 10k resistor to connect CH_PD to VCC of ESP8266 and then VCC to 3.3v(using jumper wire) of Arduino UNO
Hello IT Chop Chop, I really appreciate this excellent work , well presented and explained the circuit, it helped to get my project working. Thank You. Sathvik Saya
I need help man, I did EXACTLY what you did down to the T. It shows that it successfully compiled and uploaded the code and everything, but I'm not getting any output via the COM window. I see this video is a few years old now, so is there some extra step i need to do in 2021 in order to get this to work?
People say that ESP8266 can accept 5V into its RX, and 3.3V from ESP8266's TX to Arduino's RX is still recognized as HIGH. Thus, seems no need in resistors.
Like so many people I've found programming the ESP8266 to be impossible. I've researched every error message and tried every suggestion but without success, including this solution. However, I did pick up on the need for a good connection and in frustration I squeezed the ESP board and the FTDI connection between my fingers as it was loading. And it worked, the program loaded and ran. I don't know wether squeezing secures the connection or if my fingers act as some kind of capacitor/resistor. Unfortunately it's not a workable solution. Any comments?
I have a little doubt. Is it possible to use SunFounder Nano as an expansor for digital ports? My ideia is connect more devices on the wifi board without using the arduino(uno, due, leonando....) Sorry for the dummy question, I'm learning it.
I think the mini socket is the better socket than the micro more reliable but you can get an adapter for 01 that makes it easy to connect but interesting video thanks
Thanks for the tutorial I managed to upload the sketch, but at the end it says..."Leaving...Hard reseting via rts pin.." and nothing happens anymore, nothing in monitor serial... I even uploaded the blink example but also nothing happens.. no blinking... Is there any other step to be done?
I followed your guide exactly and do not get the same results, current from the Nano to the ESP8266 is about 40ma so I switched the power source to external and am now getting 3.3v at 174ma but if I click to open to serial monitor IDE goes red with lots or errors and says it had lost connection to the board? Any Ideas?
Hello Sir , I did the setup exactly as you instructed here.....but I am getting this error "Timed out waiting for packet header". Can't get rid of it. The internet is telling different things. Can you please suggest anything

It's not easy to use :/ I've been struggling for longer than I care to mention. I'm glad your project went well, but the upload (from espressif or the Arduino's board manager tool chain) have failed me time again on the ESP-01. I can get the ESP-12 to work no problem, so I went through dozens of forums, etc. to troubleshoot. It always comes down to power supply, which I've investigated as well; I've used an AMS1117 with a 100uF and 1000uF capacitor in different trials. I've used batteries as well to avoid current draw issues and still haven't found a way to put these modules in a stable condition for flashing....
Not worked for me... Say always "esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header" I tried different version of the connections...and nothing works...help me please!
I've wired this up the same way with an Uno and it seems like it doesn't get enough power. I've seen others say that the 3.3v pin doesn't provide enough current and that you must use 5v, but then adjust the voltage. How come you don't have this problem? Does this Arduino provide more current?
The nano seems to be more stable. I had the same problem with the uno and the mega. There is a way to decrease the current from 5v with a ohm resistor and regulator. Google that.
d to connect to ESP8266: Timed out waiting for packet header esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header i got this error
They make these usb adapters now. They're NOT programmers. You have to put in a momentary switch between GPIO0 and GND. Hold the button as you plug the usb/01s module in to your pc. Release after one second. Tada. So so much easier. Now, what you can make this pos do after you "talk" to it? It'll leave you reaching for a Wemos D1 or esp32. That's just my opinion
Guys if you get any error, unplug first the esp8266 to the arduino(either the vcc or ground) then click the upload button. When it says uploading, reconnect the esp8266 to the arduino and it will be successful. But in my case, I was successful in uploading but when i clicked the serial monitor, nothing happens. I think my esp8266 wifi module is damaged.
if i'm not wrong it is because you are using the nano just as a usb to serial ttl converter, that is also the reason why he also connect the reset pin to ground to avoid listen for the atmega328 for commands
Paul is correct. In this case, Arduino is not communicating with the ESP. We are just making use of USB to serial chip of the Arduino. But I thought he need to remove the GRND cable from GPIO0 in ESP after downloading the program! May be it still works this way I haven't physically tested.
warning: espcomm_sync failed error: espcomm_open failed error: espcomm_upload_mem failed error: espcomm_upload_mem failed Any idea what might be causing this error? As far as I can tell mine's set up exactly like yours.
Hey, Go to this link, theres a lot of possible fixes. the way it worked out for me was with the method that a user named "zurexalexis" posted. just enter in this link and "cntrl + F" for that username and try what he said. github.com/esp8266/Arduino/issues/770
also i used an external 3.3 V Power supply. just connect the ESP VCC to the EXTERNAL 3.3 Volts and connect the EXTERNAL GND to the ESP and Arduino's Gnds.
As per my knowledge , reason for the error is power shortage . If Vcc and CHPD didnt get 3.3v properly , we will end up in getting error . Try to use 5v and use a voltage regulator . Thank You .
Thanks it worked!! FInally I found a tutorial that really works :D Drive used: ESp-8266-12S IDE:1.8.5 OS: Windows 7 64 Same wiring to pins if ESPCONF errors appear, just power cycle by disconnecting Arduino from PC then plug it back in. Once again send the script
not on the arduino uno, because on tx it literally says "arrow tx" and :"arrow rx", which means to recieve tx/ rx. Thus u need to put tx to tx, otherwise, yes regualrly withtout the arrow, it would be rx to tx and tx to rx.
bruh you need to unplug the GPIO0 pin from the ground after uploading the code, after that open the serial monitor and press the reset button for the esp8266...
Give up! I tried all solution and more than 100 times of uploading i think. error: espcomm_upload_mem failed keeps appearing. Sad. Not sure if it is my board already damages.
please someone help me the uploading of code is completed successfully. but when the uploading completes esp8266 modules red led goes off and when i start Serial Monitor its not running the program and not showing any output. its showing nothing just a white screen please rply soon

Why you changed cables order ? firstly grey was last then you've changed and now blue is last .... what are you actually doing ? how can I follow your tutorial if you mixing cables ?
lmaooo follow this instead: medium.com/@cgrant/using-the-esp8266-wifi-module-with-arduino-uno-publishing-to-thingspeak-99fc77122e82 I found it much much clearer and it actually works better.
warning: espcomm_sync failed error: espcomm_open failed error: espcomm_upload_mem failed error: espcomm_upload_mem failed This report would have more information with "Show verbose output during pls help with this issue
I know this is several months ago I had to make sure the com port was right on windows and on my mac make sure it had the usb serial selected and it stopped giving me this
This helped me setup my programmer board: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-P_ecAFpUADU.html Note that you still need to install a switch to power CH_PD 3.3v when uploading.
