Programming ESP-12E / ESP-12F / NodeMCU Over Wi-Fi

[@antikasoundengineering4222]

Thank you for the knowledge, the method of delivery is clear and easy to understand. I'm from Indonesia, Jakarta, Bali

[@laenga6044]

Amaaaaaazing content .Thank you very much sir for this and for the previous video for programming ESP8266 via physical connection. You just got a new subscriber. May God lead and guide you.

[@thisoldjeepcj5]

Very good video! Hope to see more from you. Thanks.

[@dbuezas]

Really thorough and clear! Thanks Indrek!

[@marceljaxson3481]

you all prolly dont give a damn but does anyone know of a way to log back into an instagram account? I stupidly lost the password. I would appreciate any help you can give me.

@Marcel Jaxson instablaster =)

[@marceljaxson3481]

@Fernando Joseph Thanks for your reply. I got to the site on google and im in the hacking process now. Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.

[@marceljaxson3481]

@Fernando Joseph It did the trick and I now got access to my account again. Im so happy! Thank you so much you saved my account !

[@fernandojoseph352]

@Marcel Jaxson happy to help :D

[@PedroFernandez-cv8ie]

You are doing a great quality content! thnx. keep the good work! :)

[@IndrekL]

Thanks!

[@amitmargalit4551]

Love your videos!

[@ChrisHalden007]

Great video. Thanks

[@jovenianomadrid9565]

Thanks for your video my friend

[@danielhagos6080]

thex for the video. realy saved me

[@1stamyk]

Nice video! I did everything successfully (no errors, led blinking) by videotime 4:28, also sure I use same WIFI but still can not see new "esp" port in menu. Would you have a hint what else can cause the problem?

[@4STEVEJOY34]

Now that we have a program on the ESP-12E / ESP-12F. Can you make a video on how to make the program run when the chip is ready to be used. NOT WIFI. maybe run a LED on pin 12.

[@thisoldjeepcj5]

I know it's been a while since you made this video, could you explain how to add static IP, gateway, and subnet mask to web page and eeprom save as these are not char? Thanks.

[@mygpsforcegpsforce2174]

Buena opción

[@paulgrayford9296]

Hey Indrek, great video! Are you able to program the module over Wi-Fi without setting GPIO 0 to ground to set in programming mode (after programming once of course)? Thank you!

[@supermadson1]

Hey, brilliant video! I'm working on a project and was wondering; once the code is uploaded and the esp disconnected from the computer, if I then connected a battery to power the esp, would it still retain the code and be able to receive sketches from the computer without a physical link?

[@IndrekL]

Hey! Yes, as long as your computer is connected to the same Wi-fi network as the ESP module.

[@supermadson1]

@@IndrekL Thanks! My bench inspection went really smoothly thanks to your content

[@ershithvarans7029]

iam planning to file (IPR) for my own home automation project and also , I had used arduino ota libraries will my IPR will be cancel after serval test i would commercial the product

[@deroskar]

Nice Video. Super understandable and found it easy to follow along. Ist it meant to put the code you want to program under the ArduinoOTA.handle(); and server.handleClient(); funktion in the second code? I put the digitalWrite(2, millis() % 1000 > 500 ? HIGH : LOW); blink-code in there but the LED did nothing. thx

[@IndrekL]

Hey! Yes you should be able to put you code under the "handle" methods. Are you trying to flash the on-the-board LED? Maybe try to use LED_BUILTIN instead of 2. I am not sure but the LED_BUILTIN might not be number 2.

[@Aashutoshkumar-xu1zy]

Sir please make a video on How to program ESP 12E/12F/NodeMCU through arduino board

[@mouseminer2978]

Can you make a video about making a serial LCD clock using ESP 8266 E and a Garage Opener. Thanks in advance

[@elless317]

I got: "error no answer" at the end of uploading process. What does it mean?

[@rizwansaeed91]

Hi, that is great. and Dear can we upload code over the wifi only once or more than 1.

[@IndrekL]

If the code you upload over the wifi also supports uploading over wifi then you can upload again. But when you upload code that does not have the OTA library then you can't do any more uploads.

[@cassie5130]

Unrelated to this video, Your liveOV7670 project. I was wondering if it was possible to add a button to take pictures, videos and save to a SD card. If so, how would I do this.

[@IndrekL]

I recently learned that it is possible to read data back from the screen. So theoretically it is possible to take image from the screen and save it to the SD card. SD card it too slow to save image to it directly from the camera. I am planning to do a project like this in the future. I will upload a video about it when I am ready.

[@ekfariant3159]

Can attiny85 programmed with cp2102?

[@larswilting8862]

Hey, thanks for the video. Do you know a way to use OTA between two different subnets?

[@IndrekL]

As far as I know Arduino IDE sees the device only if it is in the same subnet. Maybe you can do something clever with router configuration, but I don't know much about that.

[@TradingwithJerry]

Unrelated to this video - do you happen to know where i could find an inexpensive loadcell/strain gauge that is high temp resistant?

[@IndrekL]

Hey! Unfortunatelly, no.

[@nelsonhubahib4859]

Can show how to program to watchpower to be used to solar inverter.thx

[@Север44]

Hello. Thank you for your helpful videos. I use Arduino 1.8.13 and the board version 2.2.0. The OTA example (with my ssid and password) creates a network port and is flashed through this port when working with Witty Cloud, ESP-12 and ESP-07S, BUT IT DOES NOT WORK with ESP-07 (with a ceramic antenna and a connector for an external antenna). The port appears, but when flashing through it, a message is displayed No response from device Please help me.

[@toumiaabdelkader4723]

Thank you for your help

[@quinman16]

hay man do I need to write this code to the ESP8266 WIFI shield or to the Arduino board its self, and is it possible to make a web controller that I can reprogram over the WIFI connection and be able to change the WIFI name and password.

[@IndrekL]

Hey! This is programming the ESP8266 module itself without an Arduino board. You can programm the ESP8266 module directly using the Arduino IDE.

[@antoniomarijanovic1559]

First

[@dindigulautomationwaterpro5145]

Hi. Can u please write a code to me for Nodemcu Esp12e Module thank-you. ? 1. On D2 - D2, D7 and D8 off after 30 seconds 2. On D3 - D3, D7 and D8 off after 30 seconds. 3. On D4 - D4, D7 and D8 off after 30 seconds. 4. On D5 - D5, D7 and D8 off after 30 seconds.

[@yazani19]

Hi, that is great, but can you tell me, What is "?" here !!!! digitalWrite(LED_BUILTIN, millis() %1000 >500 ? HIGH:LOW); Thax

[@IndrekL]

Hey! It is an "inline if". If the condition before the "?" is true then the first value is used, if false then the one after the ":". For example this: int a = some_condition ? 111 : 222; is the same as: int a; if (some_condition) { a = 111; } else { a = 222; }

[@IndrekL]

The above "if" could also be written as: if (millis() %1000 >500) { digitalWrite(LED_BUILTIN, HIGH); } else { digitalWrite(LED_BUILTIN, LOW); }

[@domingomikefritzb.1467]

can you make a break horn melody, like denso 2 tone? japanese sound :)

[@pedrorivarepetti]

Hi, using some other similar code I can save now wifi settings on my module so i think it is something with th e code. If are you interested on what worked I am willing to colabborate with you

[@Viraldanceworlds]

no its not i even went and bought a board with the links and it still dont work
