[@UNgineering]

so simple yet so elegant! i've just started messing with OTA programming and kept running into a wall with http server and OTA running side by side. i did one thing differently though - i implemented an async wait function, so it's not blocking the main loop.

[@harryjunior8377]

Brilliant tutorial Thank you very much. I just wanted to add a finding of my own... If you open a second instance of Adruino and set port to the USB Com Port you can still have access to the Serial monitor in the second Arduino IDE whilst still be able upload via WiFi from the First Adduino IDE. Handy for debugging. Harry

[@leedevries5660]

It worked quite OK, but I found that on a running system with 6 MQTT nodes which run all the time, if I turned up with my notebook to upgrade firmware on any node, the Arduino IDE does not see the controllers WiFi port. It only sees the port when ArduinoOTA.handle() is executed. What I do is I execute that function once a minute WHEN THE OTA flag is NOT set. At most the laptop only has to wait for a minute before the WiFi ports are recognized.

[@datasith]

I'm glad you were able to work things out!

[@bgable7707]

How to regain access to the ip address port from the IDE Another solution is to add a "fake programmer" to the "Tools" menu drop down. 1st, on Windows10, find the file "programmers.txt" . The one that worked for me was: C:\Users\joe\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.3\programmers.txt. 2. Add the following lines at the bottom of programmers.txt file, save it, restart the IDE. # ESP Wemos #2 50:02:91:AA:BB:CC (just a comment line) arduinoOTA142.name=ESP-Wemos-OTA (Drop down menu text) arduinoOTA142.program.tool=arduinoOTA (Don't know, just part of the IDE code) arduinoOTA142.ip=192.168.10.142 (The static dhcp IP addr) 3. Select "Tools", scroll down to Programmers and your devices should show up there. This is used instead of the com port which you typically choose. Note: I reserve my IP's in my router's DHCP pool, ie, MAC to IP is always the same. See "OTA Upload from IDE without 'network port'" in the article at: github.com/jandrassy/ArduinoOTA

Thanks, Lode, for the kind words. I'm glad you found it useful!

[@ericBcreator]

Nice informative videos about OTA programming! I've been thinking about implementing it in some of my projects as well. Why didn't you choose to just call the OTA.handle in the main loop, say every second? Performance issues? Or would the Arduino IDE time out (does it need a continuous handle loop)?

[@datasith]

Thanks! Yup, your instincts are correct. Whereas you can get it to work, if you start adding more tasks in your main loop like reading from sensors, moving motors, etc., then timing becomes an issue and OTA will suffer. With beefier processors like the ESP32 you can bypass this by using a separate core, but for the ESP8266 what I used is one of the better ways of handling OTA. HTH!

what is the point of OTA if serial monitor is not supported. is it possible to direct the serial port data to a webserver so the serial port output can be seen on the webpage.

[@chandanbhatia3382]

Thanks for video. I am facing one issue, Not sure if its IDE issue or something else. I tried your code from github but I am unable to find any option to see network port in Tools->Port. I can see only COM ports option. Any suggestion? I m using latest Arduino IDE 1.8.12 in widows 10. Do we have any other option to validate.

[@MrDenisJoshua]

I tryed on NodeMCU and the webserver it's ok. I then choose the net port and put NodeMCU in Restarting... Then I take an error: "07:00:00 [ERROR]: No Answer" :-( Can you help me please ? Thanks a lot

[@datasith]

After flashing the OTA firmware over serial, physically reset the NodeMCU before doing OTA (don't hold down the button, just press it once). After a few seconds, you should be able to upload the new firmware from the net port. Let me know if that works!

Your videos have really helped me learn the 8266, and the OTA stuff is awesome. However, no one ever really takes it to the next step to show how to incorporate code within the OTA feature -- Even a basic water sensor sketch. So, how does one make full-featured sketches incorporate into OTA code?

[@The_Unobtainium]

It's just so good. Could make a video how to optimize the OTA code to avoid that annoying 15 sek delay? Maybe we can use some script to poll esp8266 for reset and start OTA immediately?

[@datasith]

Heya, funnily enough, I made one already without the annoying delay: kzbin.info/www/bejne/nXeuY3h6g9V8m68 HTH!

[@PowerJiang]

Hi Cisco, ESP01 also have procedure problem in OTA. As we know, ESP01 is programmed in shorting GPIO0 to GND. Normal operation in open of GPIO0. This also a good challenge for me. Do you have good idea ?

[@datasith]

What's the problem, you can load OTA software once, and then each time after you upload the code using OTA. Am I missing something? Sorry for the late reply!

[@dozog]

One problem I see for larger code. You opened your IDE and made small modification to a rather bigger code than this minimalistic example. You want to upload, so you go to your browser and type the setflag thing. Now you will have 15 seconds to close your IDE, open it again, find and select the OTA port in the IDE and hit upload. As far as I understand the procedure, the IDE will at least have to start sending data to the device within 15 seconds. That's not realistic with bigger code. Or does your sketch broadcast it's OTA port even when the ota_flag is not set?

[@datasith]

Old sketch waited 15 seconds. New sketch doesn't. You can configure the OTA flag with an HTTP request.

[@daedalus5483]

Hello Cisco, thank you very much for your work. It doesn't necessarily have something to do with the content of this video, however, I was wondering how one can regain access to error messages, especially those in ArduinoOTA.onError, without a terminal window. Thank you for your time.

[@datasith]

One idea would be to log them to a file on SPIFFS, which would be accessible from a webpage (i.e., creating a route that filestreams the file). What do you think?

[@Ed19601]

Honestly I dont understand what you are trying to show here. I have been using OTA long time already and the OTA handle does not interfere at all and I can update over the air any time I want

[@seantalbot3178]

Hi Cisco, Two great videos, thank you. I am using two boards, i.e. an ESP32OLED (wifi and BT) and a Wemos D1 (wifi). The sketch compiles fine for both boards, but the wifi com port only appears for the ESP32. The OTA functionality works well on the ESP32. When I plug in the D1, and change boards on the IDE, the wifi com port disappears. Naturally I have run through the same setup steps for the D1. Any ideas? Thanks

[@datasith]

That's very off, I wonder why. If the code uploads to the Wemos D1, it means that the board is okay so it's a software thing. I realize it's been 8 months so hopefully you figured it out, if not, by all means let me know (apologies for the late reply).

[@vtech8716]

very good

[@datasith]

Thank you! I'm glad you liked it.

[@alx8439]

Why to spin up the whole web server to manipulate with this, instead of just keep calling OTA.handle() in the program main loop unconditionally

[@harveyschneider9644]

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

[@chndrakntpatil]

I am getting no answer error message. I tried every thing. No use. Have esp8266 12e. And use arduino r3 and jumper wire to flash initially. Ota doesn't work.

[@datasith]

make sure your mdns is woking and you can access the board both by its IP address and local domain name

[@madhukeshnp]

Can this be done out side the LAN ?

[@datasith]

Yes but it requires a WAN-accessible server where you can upload the firmware file. Once uploaded then the server needs to notify the ESP8266 that a new firmware file is available. It's doable by yourself, but tricky. If you check @AndreasSpiess channel, he has a service that does this for you.

[@madhukeshnp]

@@datasith thats really interesting. It would be great if you do a tutorial on it. I haven't come across any such tutorials on KZbin. I wish you you teach us how to do it. Thank you in advance.

[@petebowcott8348]

Thanks so much for this, it's such a great explanation as ever!! and it worked straight out of the box like a dream! I also managed to change it to work with ESPAsyncWebServer with no problems! I am also looking at your tutorial "ESP8266 Web Server Upload Files Quick To SPIFFS Flash Memory Over HTTP w/ Arduino IDE", as I will also probably want to be making changes to the pages my esp8266 is serving. I notice (in reading the code to try and understand it more, I don't like to just cut and paste ...) that the ArduinoOTA.onStart appears to be able to update the SPIFFS as an alternative to the sketch, but I have no idea where ArduinoOTA.getCommand() is set to U_FLASH and can't find anything about setting it to U_SPIFFS? Any ideas or should I just use the curl command over HTTP as explained in your video? Thanks again for all of your help, you make exploring the esp extremely clear and accessible to me!! Pete

[@datasith]

hey pete, i'm glad you found it useful-and, most of all, that it worked! that is a really good question, to which i don't have a perfect answer as i haven't tried it myself. on the IDE, i suspect if you select the option "ESP8266 Sketch Data Upload" it'll send the contents of the sub-directory "data" inside your sketch folder to flash. obviously, there's an underlying tool that i had to teach myself about today (thank you!): what you'd want, outside of the IDE, is something along the lines of "python3 espota.py -i -I -p -P [-a password] -s -f " to send your data to the flash file system. here's more info about espota: github.com/esp8266/Arduino/blob/master/tools/espota.py really, really good question!

​@@ramakant610 Serial Monitor and Putty show the data transferred over USB. For OTA programming, there's no USB connection. You can see the data if you store it in a variable (RAM), or a text file in SPIFFS or SD Card, and then serve it over HTTP as a using the server.on() and server.streamFile() functions.

[@balaramaraju4135]

Can i upload code to esp8266 through ota from Android??

[@datasith]

In theory yes, but you'd need to find an app to do so-or write your own. I think there's a way of uploading .bin files through the webserver, and have the ESP8266 update its firmware once you do. I'll do a demo in the future if this is possible.
