• Description:
In this video I go over the process, step-by-step, of how to use the Arduino IDE for programming your ESP8266 wirelessly (Over-The-Air), that is, without being connected to the computer's USB port. I've covered in other videos how to use the Arduino IDE to upload code to the ESP8266. However, I've done this by connecting the board over USB to a computer, and using the IDE's upload function.
In this video, I'll modify a built-in example of the firmware that's needed for OTA. Once modified and uploaded over USB, this firmware will allow selecting a special port in the Arduino IDE, and use the wireless (OTA) programming method for additional uploads.
~~~~~~~~
On Windows, please make sure you install either iTunes or Bonjour so that your computer can see the ESP8266 over the Wi-Fi network (it uses mDNS):
support.apple.com/downloads/b...
Also, do not forget that OTA updates only work with ESP8266 boards with at least 8Mbit/1MByte memory (not the ESP-01).

Outstanding trick. Thanks again to you and the whole team providing these tutos. May I share 2 issues I got with Windows_10 trying to implement the OTA. 1) Mdns capabilities thanks to Apple "Bonjour" software: little puzzled with all the download possibilities of the webpage given in the link. In fact, one should pick "Print services for Windows". Once downloaded, don't run it: open it with WinZip or WinRar to just get Bonjour32.msi or Bonjour64.msi accordingly to the local systemThen, get to the firewall to authorize "Bonjour services" both private & public. 2) When trying to connect OTA, the arduino IDE stopped: java.io.IOException: Cannot run program "python.exe": CreateProcess error=2. It turned out that although installed on the computer, Python is not declared in window's path ! So, make sure that this point is ticked: if not, just fix it (how-to here : www.howtogeek.com/118594/how-to-edit-your-system-path-for-easy-command-line-access/)

We owe you a drink! You're absolutely right, so thank you so much for the tips to improve the OTA process. We'll add them to the video description. In the future we want to repeat some videos for Windows users, and we'll definitely add this topic to the list!

@thomascziesla3768 7 років тому

thanks a lot - I faced same issues on Windows10. I had to restart PC to get Bonjour Service working. Firewall settings - important hint! I used: support.apple.com/kb/DL999?viewlocale=en_GB&locale=en_GB and I had to install python 2.7.10 as well (as per my research v.3.5.xx an above do not work with Arduino, so I installed 2.7.10) - while installing don't forget to add python to path variable (option to be set in install parameters)

@Andreas-rt5sm 5 років тому

In my case, even a empty sketch uses over 50% program storage, what makes it impossible to upload a new sketch after one is running. Was there a change with the arduino surrounding? I use the latest AtmelStudio with visualMicro and also tried with the latest Arduino IDE 1.8.5. Do you guys have the same problem these days or do you have a idea what I am doing wrong? Thanks a lot.

@datasith 5 років тому

Hey, Andreas. Thanks for watching! An empty sketch uses 246063 bytes, which means you have a board with only 512KB of flash (maybe an old ESP-01?). The simplest solution would be to use a different board-the SPI flash can go up to 16MB. Best of luck!

@Andreas-rt5sm 5 років тому

I have a ESP-12F but I combile with the Generic ESP8266 mode. So thats why my combiler shows me 51%. But with that in mind id should work with uploading a new sketch. Unfortunaly until now the ESP crashes after uploading a new .bin file. I will work a bit more on it the next days. Thanks for your input, this clearyfies a lot to me.

Once you flashed to OTA firmware in do you have to add that to every sketch you upload?

@datasith 5 років тому

Yes, if you want to keep the OTA functionality. The minimal things you need are: #include #include #include char ssid[] = "xxxxx"; char pass[] = "xxxxx"; void setup() { // Wi-Fi setup ArduinoOTA.begin(); } void loop() { ArduinoOTA.handle(); // For OTA }

@nicolascoquin7760 3 роки тому

I was able to upload the OTA example without issue (without the blink code). My ESP connected to Wifi network and gave me its IP address. However, once I restart Arduino, impossible to find the ESP in my ports. Is there something I need to check on the IDE itself ? The ESP is powered from a wall plug 2 meter away from the computer, both on the same network. It's an ESP-12F module. If anyone has an answer, that'd help a lot !

@rgmtb 4 роки тому

My Arduino IDE is not prompting me for a password if I uncomment out the password section. Everything works fine and I can update the Wemos OTA when no password is required. I'm getting an authentication error so the board is looking for a password, but I'm not getting a prompt to type one. Any ideas?

@rgmtb 4 роки тому

OK, I take it back and not it's working. Strange? Another question for ya, with the password on I'm not getting prompted for it if I use the webpage to put the board into update mode. So if I call "setflag" I can upload new code, but I don't get asked for a password? How come?

@datasith 4 роки тому

Glad it works. I think the password gets stored in your browser's session. Try incognito mode, and after logging in, try closing the old window and opening a new (incognito as well) one.

@KP-nc9gk 5 років тому

Mine works without the additional ota flags. I just let ArduinoOTA.handle() be called inside the loop() along with my program. Great video! Thank you very much. :)

@backwoodsbrewer 5 років тому

I have found that if you have a lot going on in your code, or if you have delays, then it can be a little problematic. Best solution I have found is to use millis/previousmillis instead of delay(), and also make sure to define the esp8266 port. Even though it says it defaults to 8266, setting it in the code fixed a lot of issues for me (ie., "No response" errors). Also, if you program it over USB, be sure to do a hard power cycle or else OTA upload will error.

@lordhelmchen100 7 років тому

Great Video, very good production Quality as always IMO! But why didn't set time_elapsed = millis() and then in the while loop ask time_elapsed > (millis() - 15000) ? Because what if your setup routine already takes up like 5 seconds? wouldn't you then have only 10 sec left for programming?

@datasith 7 років тому

Thanks for the kind words :) Yup you're absolutely right, the main reason we used 15sec was to account for cases where *setup()* takes a long time. Still, there could be cases in which it takes longer than 15sec and OTA wouldn't be available at all. It was meant as a quick-n-dirty demo of what's possible, but still using what you suggest would've been better! Another note is that the OTA code only runs either when millis() rolls over (after ~49 days) or when the board resets. If we really want to avoid needing physical access to the board, we'd need to tie a GPIO to the RST pin, and establish a way (e.g., web server path) to trigger the board reset.

@lordhelmchen100 7 років тому

Or couldn't you just write a function which initializes the OTA code for a time of 20 secs and call it based on a web server request? This way you wouldn't waste one GPIO ;-)

@datasith 7 років тому

Yup, exactly!

@datasith 7 років тому

Hey Anas, thanks for watching; we're glad you liked it! In the past that's been true, however, there were plans to increase it. Poking around a bit I found the old thread where it was being discussed: github.com/esp8266/Arduino/issues/570 HTH!

@omaryanas435949 7 років тому

Hi, thnx alot, I went through the post, and the conclusion was that connecting more than 4 clients to an esp8266 server is possible, however, the connection will be very slow and inconsistent, but the final solution was to use a router as an AP, which in my case will cause a problem in case the wifi password was changed, because it would mean changing the password in every single client.

I have done this with Arduino IDE in Win 10. It works as in the tutorial here. Many viewers do not realize that the libraries allow the code to be transportable between devices. Also be aware that serial monitoring takes a lot of resources; CPU and Memory. I use conditional compilation to only use the print statements during code development.

@Disillusioned_one 7 років тому

You said the esp is not accessible so use ota programming, but then have to press the esp reset to enable a 15 second programming window.

@datasith 7 років тому

Yup, and we also need to have it connected to the USB port at least once to upload the firmware the first time. If you wanted to use the 15 second after reset method, you can connect a GPIO to the RST pin and have a way to trigger it. This goes beyond the scope of the video so we decided not to include it, nevertheless, good point!

@ljl451 6 років тому

What's the problem with leaving ArduinoOTA.handle() always in the loop without using the ota_flag variable? ArduinoOTA.handle() is a small overhead method designed to be used in that way so that OTA is always available without the need to reboot the board.

@datasith 6 років тому

Using the method increases the overhead compared to using the flag, small as it may be such difference. Thanks for bringing this up!

@ljl451 6 років тому

The overhead introduced by ArduinoOTA.handle() is just an IF statement. The same overhead that you introduced with your ota_flag. void ArduinoOTAClass::handle() { if (_state == OTA_RUNUPDATE) { _runUpdate(); _state = OTA_IDLE; } }

@datasith 6 років тому

Hmm, it seems you didn't really have a question, so we wonder what was the point of original comment. In any case, we can get into compiler specifics, but we choose to defer the discussion for a later time.

@anumsheraz4625 6 років тому

Great stuff... Well explained video of its kind. However I had issue after uploading the Wifi boot loader.I couldn't see Wifi port even if I restart my Arduino IDE. This solution might help someone: 1. make sure your PC is on same wifi network as on which you configured your boot loader program. 2. if still doesn't works, go to preference > Network and turn off proxy , restart IDE. 3. if still doesn't works, make sure your Wifi network is not blocking some contents from Firewall (usually happens in Universities or restricted Wifi networks)

I am using Windows 10 Prof. I install python as needed. Still ports does not show up. I can ping the board just fine. What did I miss?

make sure you have mdns installed.

Hi Thanks for your videos .. I followed the process and upload via usb . I see in the ide the new ESP port but when I try to do the ota upload i get an error in the IDE saying "Cannot run Python.exe" . What have i missed ?? Regards Meir

@datasith 6 років тому

Thanks for the kind words, Meir. On Windows you need to install Python. And, if it's already installed, make sure it's on the Windows path! www.howtogeek.com/118594/how-to-edit-your-system-path-for-easy-command-line-access/ Thanks for watching our vids!

ACROBOTIC: thanks I installed python 2.7 as I saw listed in other comments. One last question how can I ota with the password without pressing the reset as you showed. In final setup the esp will be installed in locations that will be difficult to access.

Will it work on Linux ?

@datasith 5 років тому

Yup!

@harveyschneider9644 5 років тому

If the upload fails at 0% the firewall on your computer is blocking the ESP from downloading the file.

> I used the exact code with the same board Assuming this is a factually correct statement, then double-check your power supply. Otherwise, make sure that you haven't changed anything in the loop() function.

@andrewmosqueda994 5 років тому

@@datasith Thank you for the quick response. I am using the laptop, plus I bought the same board. Here is what I have in the loop function: bool ota_flag = true; uint16_t time_elapsed = 0; void loop() { if(ota_flag) { while(time_elapsed < 15000) { ArduinoOTA.handle(); time_elapsed = millis(); delay(10); } ota_flag = false; } } and it is showing this in the monitor: Connection Failed!

By following this video, also look at the pinned comment and video description. Thanks for watching.

ACROBOTIC im sorry for the confusion i meant the ota programming/uploading method

@pavankumar693 6 років тому

Cisco when I dumped the code into the board and I typed the password but it is not uploading please check it once!

@datasith 6 років тому

Is the board listed as one of the options in the Tools menu?

@wishwaweerasinghe5425 6 років тому

Thank you very much for the video. It is a great demonstration. If I have a "ESP8266 Esp-01 Serial Wireless Wifi Transceiver Module" and an "Arduino Mega board", is there a way to connect them together so that I can upload new sketches to the Arduino board OTA? I bought this one: www.amazon.com/gp/product/B01EA3UJJ4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 But they don't provide much info on how this could be connected to Arduino board so that I can upload new sketches over the air. Appreciate if you could point to some resource. Thank you!

@datasith 6 років тому

You could but it's not trivial. You can wire the UART ports together (Tx and Rx), and have the ESP-01 write out the uploaded sketch to the Arduino Mega using Serial.write() (doc: www.arduino.cc/en/Serial/Write). Best of luck!

@Akaki85 5 років тому

Thanks for your tutorial, but you forgot to mention that Python is also needed to be installed on your PC.

How to program it without resetting

@HamzaHajeir 5 років тому

you can set a button to do that, changing the condition (ota_flag) to (digitalRead(buttonPin)) or combining them together, as : (ota_flag || digitalRead(buttonPin))

@datasith 4 роки тому

Did you see my latest video on OTA, I show a different way where you don't need a button. I set a route that you access to reset the board.

@mikelemon5109 7 років тому

This OTA is useless and uncomfortable guys need to start developing OTA like on the roborio from FIRST

@datasith 7 років тому

Yeah, well, that's just, like, your opinion, man 😂 More seriously, we agree that OTA is not very robust at the moment on the ESP8266, so if this is a critical feature for your project perhaps other boards are the way to go!
