The EASY Guide To Over-The-Air (OTA) Updates With ArduinoOTA

[@Sikuq]

Excellt step-by-step video. Got me up and running on my Adafruit ESP32 Feather in no time. On my IDE 2.2.2, I don't need to restart the IDE. Thank you so much.

[@programmingelectronics]

Glad it helped!

[@OFCIFR]

The title is not a lie, thank you so much, it's working perfect and needs just two lines of code, I'm mindblown

[@programmingelectronics]

Great!

[@burhanuddinbhiwaniwala618]

Your contents are very very informative....but I love watching your videos coz u explain it so well nd even your voice Is amazing

[@programmingelectronics]

Thank you so much 😀 - really appreciate the kind words!

[@AntonySimkin]

Man! You videos are very well made. Good quality, good narrating, nice content. You deserve more subscribers! No doubt!

[@programmingelectronics]

Thanks for the kind words!

[@leelipinski4667]

Hey man. That was was amazing. I watched the 90 minute basic start up video first and came to this WiFi video as the Arduino copy board I bought is a Arduino WiFi board. So I thought this would be handy as my computer couldn't find any of my ports. Think its just the driver needs updating. Whilst that's updating I'm watching some more videos on my pad. Thanks for sharing 👍

[@programmingelectronics]

I appreciate the feedback!

[@zeeshanafridi798]

Very well explained! and yea that troublshooting thing you explained is super helpful, I faced it numerous time. Thanks for making it super easy

[@programmingelectronics]

Thanks Zeeshan! Nice write up on this article by the way!

[@crissproduction]

Very informative - as always! Thank you

[@programmingelectronics]

Thanks so much!

[@fabianlam4992]

Clean and clear explanation. Thank you so much!!

[@programmingelectronics]

Thanks!

[@Mr31Vince]

I use ArduinoOTA all the time with my esp32 projects and it works even better with PlatformIO rather than the Arduino IDE. ArduinoOTA also works in parallel with ESP Now comms, but needs a few tweaks to work correctly.

[@programmingelectronics]

Thanks for passing this on!

[@johneagle4384]

Super! Thank you. Very interesting and useful at the same time.

[@programmingelectronics]

Glad it was helpful! There is more functionality in that OTAlibrary than I dive into here, but hopefully I covered the basic enough.

[@jonathanm9436]

Love your work man. And I really like having your face on the videos now too - you look at least as cool as your voice sounds! 😊😊 This OTA capability is fascinating. I've not used ESP32 yet, but you have piqued my interest so I'll be looking for any reason to replace my go-to Nano platform.

[@programmingelectronics]

Thanks so much for watching! Arduino just came out with a Nano-ESP32 which I have been playing with some - they seem pretty nice so far.

[@jonathanm9436]

@@programmingelectronics - nice to know. Thanks!

[@Ahmedhkad]

All my projects had ardunio Ota, when you used once no usb cable again, but I wounder how many times I can upload codes, is there a limit to overwrite code?

[@programmingelectronics]

Great question!! The limit would be no different then when using a USB cable since the update is happening on flash memory,

[@HKGoldenMrA]

ArduinoOTA is super cool. I have a keyboard that can update the key mapping though bluetooth. Is it the same technique?

[@programmingelectronics]

Great question! I'm not sure to be honest.

[@mtraven23]

does it keep that mapping after all power is lost? then at least some part is being flashed, probably not the whole esp32, just a specific partition. Which is what is actually happening here too, the flash is divided into partitions, 2 biggest are identical OTA0 OTA1. the new program is store, entirely on the other partition, before the flash happens..cause breaking connection during a flash is b...a...d.....bad! but your keyboard probably has another set of partitions for the mappings without having to disturb the main program memory .

[@SONUKOL1]

You explain very simply and easily ota update, can you rebuild it and update ota from internet

[@programmingelectronics]

I'm exploring this right now - hope to have a video with the basics on something like this soon.

[@KenRossPhotography]

Thanks! That answered several questions I had 😊 Something else I came upon recently that's not OTA but sort of related; I saw where someone had created a web page with an "install" button to do the initial deployment of the complied binary to a computer-connected ESP32. I thought this was such a great way to make it low friction for non-tech folks to install projects onto a device and I was wondering if you had a video that walked someone through setting up a deployment option like that.

[@programmingelectronics]

That sounds neat! I don't have any videos like that on the channel yet, but thanks for this content idea!

[@wali7862]

​@@programmingelectronicskindly make one 😊

[@MrI8igmac]

Im working on a drone build, the hotkey boot is a real pain on my model. Nice video🎉

[@programmingelectronics]

Thanks for note!

[@anyhumble946]

its cool when we have to program multiple esp boards, multiple time. (may be programming 30 esp based sensor nodes)

[@christiane321]

That is so COOL!

[@programmingelectronics]

I agree!

[@Mr31Vince]

The computer you are uploading from can also be connected via ethernet rather than wifi to your router.

[@programmingelectronics]

Thanks for adding that!

[@ernestoambroggio6334]

Great job! can it be done without being connected to the same network? i.e authomatic firmware/code update from different places

[@tonyhodgson6744]

Hi, did you ever do a video that done OTA over cellular nedwork. ive got a sim7600e connected to my esp32 and would love an OTA over gprs cheers tony

[@melvin-rh2gr]

Hi i am using ESP wroom 32 to test OTA technology. So i have uploaded the code, since i don't have any other battery source, i am powering up esp board with another laptop source but in my laptop it is not showing network port. What could be the problem??

[@programmingelectronics]

Just to verify, both esp32 and the computer are connected to the same WiFI network? Can you verify that your ESP32 has connected (ie. are you printing out to your serial monitor that it has connected to the local WiFi?)

[@melvin-rh2gr]

@@programmingelectronics yes both esp32 and laptop is connected to same network

[@melvin-rh2gr]

This issue is solved. It was problem with the network, i tried connecting with another network. Now if i have to upload the code from distant place, what can be done(i.e. if i am not in the same network range) ?

[@programmingelectronics]

@@melvin-rh2gr Yes, can be done, but requires some additional steps, I'll see if I can make a video about it.

[@dan_m320]

Is it possible to upload the code trough internet (from a different network)?

[@programmingelectronics]

Great question! I am curious of the same - if I can find something that looks reasonably approachable I'll post it for sure!

[@jrippon]

Thanks for a great instructional video. I'm wanting to try using OTA on the WeMos D1 mini (ESP8266). I understand the principles are the same but other videos I've watch about it (admittedly all of them several years old) refer to installing Python on the PC. Do you know if this is something that's still required for OTA on the ESP8266? Thanks.

[@IceCreams62]

Hi. Why the OTA handle is not on setup ?

[@programmingelectronics]

Great question! Since setup only runs once, the code that manages the actual OTA process wouldn't be able to run in the loop. At least that is my understanding.

[@mr.bianchirider8126]

I get the same problem of having to restart the Arduino IDE or even restart the PC. The ease of not having to retrieve the MCU a plug it in versus restarting the IDE/PC is incidental. It’s a minor bug and one day, hopefully, an Arduino Guru will fix it.

[@larsniklassonhede3798]

In ESP-NOW it's a WiFidisconnect so I belive that is the problem to use OTA here. I don't know how to get around it.

[@tonyp4894]

Great Tutorial. One Question. I have three ESP32 Cams in different locations. I noticed that the OTA program sets the ip address of the network port. I have tried changing that address, but it would not change the IP address. How can i set the OTA initial code so that it will update to the right camera, and not accidentally erase the code of another camera? Thanks, Tony

[@Mr31Vince]

It's not the OTA that sets the IP address it's your router. The best way around this is to set a fixed IP address for each esp cam in the SetUp section of your Arduino code, then you can upload to each cam separately as required.

[@tonyhodgson6744]

Hi, Got this working perfectly, thanks. now i need it to work over cellular network (4g). can anyone guide me to such a good guide as this one... cheers

[@programmingelectronics]

I'll see if I can add one! Thanks for the recommendation!

[@TonyHodgson-e9q]

Brilliant, thanks, look forward to seeing that. Ive got a sim7600e connected to my esp32....

[@ElvinAsadov.]

just perfect no word

[@programmingelectronics]

Thanks!

[@ngobduong8066]

I have some problem while using OTA with ethernet w5500

[@sathviksathish1450]

OTA is cool I am working on a project where WiFi network are diff how can i upload the updates via cloud to esp32

[@binisol7353]

Great video but What if i was using Wifi Manager?

[@James-mv9qx]

Hey mate this is a superb video, straight to it with no fluff, gets a like and sub from me. Just wondering if you have much experience with AWS IoT ? There's a definite gap in videos for that on YT, could tap into a niche there!

[@programmingelectronics]

Thanks for the recommendation! I have used AWS for things like running up machine learning models, but have never used there IoT service... Is there a specific AWS IoT feature you are hoping to use?

[@durairaj5747]

so simple tutorial very useful but one doubt whats that password stuff while uploading the sketch which password should i need to enter in to that? please help me im struc there.

[@juanperezgarcia9963]

Could you do ota updates over different networks through ethernet using arduino giga?

[@tharonerussianman]

Unfortunately, it gives me an error requesting ipv6 for some reason

[@AnotherCG]

Works

[@skeldon66]

Thanks

[@programmingelectronics]

I hope it helped!

[@Websand64]

Why is it not possible when using an Arduino R4

[@programmingelectronics]

The Arduino R4 does have an ESP32 on board, but it uses a different primary processor and I am not sure the ESP32 OTS library works with it. However, with "Arduino Cloud", you can do OTA with the R4, here are some docs - best of luck! docs.arduino.cc/arduino-cloud/features/ota-getting-started/

[@zlackbiro]

Can we do OTA using GSM module? 😂 That would be savage...

[@nidhansudharsan3135]

❤

[@programmingelectronics]

Thanks for watching!

[@sabonimahmenna5920]

now you should delete the other video , it cost me another esp32 cause i thaught something was wrong with my first one

[@programmingelectronics]

Sorry about that!

[@norberthartmann5075]

nice stuff - but not stable....
