Common Compiling Errors in Generic ESP8266 or NodeMCU board | ESP8266 projects 

Just let me know, should I also upload these kind of error solving videos?

A last-minute update! Since all else had failed, I un-installed and re-installed the Arduino IDE, and suddenly all is OK (no "Cannot compile for board ___ error) - so I'm back to working on errors that I hope I can fix. Thanks for your video. I may have to call on you again!

The subject is the very popular problems which new makers faces... thanks...

Sir this was helpful...continue the series

Thank you for your help!

For home automation project , it need to reconnect supply cable for every 5 minutes to work the node mcu what to do

Great job sir it's really helpful☺️😊

Thanks a lot for this.!

Helpful video,thanks

My program compiled, but with several statements commented out. While trying to correct these errors, (removing the comment // one line at a time) when suddenly I got the message "Error compiling or board Generic 8266." Your video seems well worked out, and I tried un-installing and re-installing the generic 8266 board - with no solution. Same message for generic or for NodeMCU. What really bothers me is that I have made no changes in either hardware or software that would cause the board non-compile problem. Any ideas??

Hey Thank you man Great stuff really helped !!

u r really awesome...ur videos help me a lot...thank u so much..

Truly thank you sir.....🌹

Hi, At the end of uploading my sketch I get this error "the selected serial port does not exist or your board is not connected". I am trying to upload to a Node MCU. I can see Com 4 is selected in Arduino IDE and the port shows in device manager. In fact upload proceeds ok because i can see the led on Node MCU blink but at the end the LED also goes off. Can you please help with this?

Woww...my problem solved... love you bro☺️

sir i have an error...... cmd": executable file not found in %PATH%

debugging is one of the important areas in embedded or software projects, really great work. Should post more issues and solutions for them. Any solution for the Override related issues faced during compilation of .ino files for ESP8266 modules like 8266- ESP01S

Could you mention about the major problem in nodemcu i.e the stack dumps and exceptions in it. How to rectify this ?

Hey I really need help with an issue i have. *So here is the problem.* The sketches (doesn't matter which) I upload will go uploading till a 100%. After this the sketch does NOT do anything at all. I tried an empty sketch with just Serial.PrintIn("Working!") in the loop command, but no response. I get no errors while uploading, it just goes to a 100% and says done uploading. *My setup* Adruino IDE NodeMCU ESP8266-12E All settings checked multiple times and changed but that did not solve the problem. While uploading the light flashes till its done. I hope ANYONE knows what this is or does. I got mine from China and i'll probably have to ask to get my money back.

Thanks for your video.

Thank you so much brother :)

thanks for your help

Very useful video. Thank you

error compiling for board nodemcu 1.0 - 12e module What shall I do for it?

can you help me find the esp8266wifi.h library ? i need the specific library to use in thingspeak esp8266 library

Thanks bro for solutions

Hello I'm having a hard time with Error compiling for board Generic ESP8266 Module.can you help please?

Sorry..can i ask you ? why it's always show error downloading that json packages when i open the boards manager ?? i copy that and paste in the preferences and nothing happen always error

is there any way to send data from firebase to nodemcu for displaying the data? pls reply ASAP

when uploading code to arduino or the node mcu i.e esp8266 i am getting a compilation error of ""HX711.scale(D5, D6)"" or lines related to the HX711.scale command can you tell me how do i resolve this

Do one thing, make a very very brief tutorial on how to upload the code on ESP from very Basics, like from installing the boards and all that stuff... Most problems should get solved with that itself..

WHENEVER I AM TRYING TO COMPILE THE SKETCH,I AM GREETED FOLLOWING ERROR -> OUI.H:NO SUCH FILE OR DIRECTORY.PLS HELP!

I am facing Issue on compiling, I am using Arduino IDE 2.0.4 perviously Installed ESP8266 library which is not visable right now on list but installed in system because i saw this board and example. when i try to upload code it try to find reset button and itry to push and hold that but upload failure.... can you please tell me why it happen i also try to upload on other NodeMCU but issue is same...some days back it works fine on NodeMCU and ESP32

Hi I am making a temperature sensor with a d18b20 and node mcu esp 8266 and I copied a working program downloaded all libraries is set on the right board and when I try and verify I get a error saying multiple libraries found even though I downloaded them once does anyone know how to fix this problem? Thanks

thank you so much

how can i solve this 'httpd_req_t' was not declared in this scope

Leaving.. Hard reseting via RTS pin... on ESP8266 NODEMCU?

I'm still facing a problem in compiling codes for nodemcu esp8266

Bro my nodemcu was not show to be connected and when I compile the error was #10 filename pls solve I have to submit my project

Sir please tell me the error as data.h no such file or directory not found

Thanks.( I had the first error too)

I am facing a compiling error. I am newbie on ESPE32, mine is generic one. The error is warning: espcomm_sync failed error: espcomm_open failed error: espcomm_upload_mem failed error: espcomm_upload_mem failed I search on internet but there is no clear solution. It result with any sketch that I upload. How to set Arduino IDE and ESP32 for flashing? Thanks again

can you do a video compilling errrors on a arduino uno/nano

Thank you

Thanks you

sir nodemcu up program so same error error : espcom_uplode_mem failed

Im using nodemcu 8266 my problem is input pin D5 and output pin D6, the D5 and D6 is not declare

I have one error for compilation. (Error compiling for board node mcu 1.0(esp-12 emodel)

hey, I found this very interesting. but at the moment I stock with this simple setup: void setup() { pinMode(7, INPUT); } void loop() {} It sends errors in the Serial Monitor (115200 Boud: pretty interesting things like "Jan 8 2013") As you can see there is no Serial set, it's just the pinMode set and it goes crazy ..?! I wanted to connect a Button but it seems to simple. Wifi works, Button not...

thank you sir

yes obviously do this problem solving session

Sir i have a same error i.e a library named blynk- library-master already exists...

I also uploaded some codes through generic esp8266 board, please help to Replace Esp8276 Old mode

thnx bro.....👍

If it's possible you can help me? how can I connect to any port in my computer I think my Arduino is blocked on com5! If you can Answer Me of this I Would appreciate, and Thank You For Your videos I really do Love It!

i use nodencu esp12e and while uploading the code it keep showing "esptool.fatalError: timed out waiting for packet header" even though i changed a lot of cables and decrease the baud rate or increase the baud rate. what should i do? i have tried so many times
