thank you so much I spend whole 24 hours to get it to work and it works you saved my life man good luck
I'm very very glad that I managed to find your video. This will be of great help to my current project. Awesome work Tomasz, keep it up!
Thank you, Paulo!
I just started to see this video
and can say PERFECT, PERFECT, PERFECT
wish best for you and good luck 🍀
Thank you so much, Hamid TB!!
Very nice websocket tutorial, love your video quality!
Thank you, Hizbi!
Браво братле!
Awesome tutorial! Thanks alot
Thanks! I'm glad it helped!
Love it :) more sucg tutorials please :)
You are such an Angel thanks
This is a great tutorial. Easy to follow and understand. Great explanations. This has helped me a lot with a project im working on. Thanks Tomasz!
Did you manage to do it? It is not working with some people
@@Ares-vh9qz it's a bit tricky to set up.. I haven't completed it, because my project has different requirements. Everything ive done according to the tutorial has worked well, even though I broke my head open few times over small errors on my side.
Thank you for this it’s great thank you
amazing, thank you
Great Video And Good Explaination 😁😁
Thanks, Rizmy Abdulla :)
Thank you so much. Very educated and professional coding. Could you also provide a documentation for controlling multiple ESP32s?
Nice video. Just want to know if there is any limit on the max number of esp32 (at various locations) that we can connect using your explained method?
Stary, ratujesz mi życie, teraz jestem biedny, ale po wypłacie aż wynagrodzę Ci to jakimś szeklem, tylko prosze dalej rób to co robisz :D
hej dzieki, ciesze sie ze pomoglem
Novamente parabéns, conteúdo excelente, obrigado
Real good video, thanks. I think you lost a lot of people on the json part. It can be confusing if people do not know json format. Maybe do a video on json format and sending back and forth between client and host
Hello Tomasz! One question. When you started the project you selected "NodeMCU-32" board. The setup and the code Is the same if I use another ESP32 like ESP32 from espressif? I have a ESP32 devkit-v1
Thanks, great video!
Parabéns excelente vídeo
Hey, Why didnt you use AsyncWebServer or AsyncWebServerSocket? are there separate use cases for async one?
Dziękuje ci, pomogłeś mi ogarnąć sterowanie robota przez telefon na olimpiadę z mechatroniki.
Hi Tomasz,
Thanks for your video and it very interest project .I was programing the three project and I had core problem the three program it the same project but the esp project I modify the program for esp8266 .
But the api gateway websokets server not connect .
The Wi-Fi connect is done already
On the esp8266 on monitor the massage show : WS disconnect
Hello! Do you have the exact version of the .yml file for serverless on github? I am getting the error: "Cannot resolve variable at "resources.Resources.ClientsTable.Properties.TableName": Value not found at "self" source" when I use yard deploy and I think my code is the same as yours
hey ,can we establish a websockets connection using only soft AP on a esp32 without internet ?
Hi Tomasz,
hope you're well.
I am facing some issues when it comes to creating a path for the serverless AWS template. 00:41:00
very helpful video. thanks you
Hi Tomasz , thanks a lot for your great video, I learned a lot from you
- do you have a tutorial how to make LittelFS run on ESP32 step by step (not ESP8266) from PlatformIO, I don't see any video for it on the network
Hey Eran, I don't have yet but I've managed to configure LittleFS with ESP32 and I will make a video about it soon.
Hi, I need to make this with ESP-IDF. Could you show this implementation, or just code?
thanks for uploading this video, can you make update for this video using azure
Nice walkthrough and explanation. Why don’t you have more subscribers and views? Is it too complex for most viewers? Is it too involved? Don’t you match what people are searching for?
Thank you, Edwin. I think the channel is still too young as it's only been 16 months since I've started uploading videos. I hope the algorithms pick it up soon :)
Please make tutorial how to control more than one esp32, please...
Hi Tomasz, I'm fairly new to this IOT stuff, i've one query, is all these web server using AWS, websocket free or we need to purchase some stuff? You didn't mention anything so it seems this all is free and we just need to purchase esp 32, led , resistor & breadboard.
In addition to above, if I wish to create cool IOT interfaces controlling stuff online, I need to learn JavaScript, aws & Esp 32 languages with their several libraries etc, is that right, or something else is required?
You have to establish an AWS account. It has a small number of free connections per month but as volume goes up so does cost.

Hi sir, I don't really have experience in Arduino, but can I apply what you explained in this video by using esp8266?
Hi HUSSIN, yeah I think connecting to WiFi and using WebSocket client should be almost identical on ESP8266. You can also check my old videos about ESP8266 they might come useful to you.
How do I know my current home IP address? Without it I can't access my home network from anywhere...
sir WS disconnected is poping again and again
Panie Tomaszu, panski project "Control ESP32 from Anywhere in the world" zwrocil moja uwage w zwiazku z tym ze tej zimy padly moje lithium battery zasilane przez solar panels i calkowicie stracilem mozliwosc wgladu na moja polane kilkaset kilometrow od domu. Postanowilem wiec kupic generator ktory moze byc odpalany przez remote control a to daje mozliwosc zainstalowania w nim ESP32 bo start jest automatyczny i choke jest automatyczny ....calosc zasilana z bateri 12v. Nie jestem z zawodu programista, kiedys naprawialem telewizory a arduino traktuje jako hobby . Moze to bylby jakis pomysl na przyszly projekt...dziekuje
Witam, pomysl jak najbardziej ciekawy, dziekuje za zainteresowanie kanalem :)
Hi, I have a question about at 41:07, I do not use macbook, I use code in window 11 so where should I paste the template in vscode?, I also download git for windows, but still dont know how to paste it, since it says --template-url not command found
Same problem...... I didn't understand..... Hay if you solved it can you please tell me....
@@jagdish9533
for windows
npm install -g serverless
npx serverless create --template-url github.com/ttarnowski/serverless-aws-nodejs-typescript-v2/tree/main --path websocket-server-api-gw
40:56
Sir how to get that VS Code terminal in windows?
Pls help
hello,
try either gitforwindows.org/ or ubuntu subsystem on windows: ubuntu.com/wsl
any alternative for aws?
can use normal server?
yeah, you can use a simple websocket server hosted somewhere on the internet to achieve the same results. BTW I'm working on something to simplify it so AWS won't be required :)
@@tomasztarnowski4434 thanks alot
I'm waiting for it...
where's the code of serverless.yml?
I keep getting this error and not sure how to handle it:
[128400][E][WiFiClient.cpp:313] setSocketOption(): fail on -1, errno: 9, "Bad file number"
WS Disconnected
Hi Aaron,
this error: [128400][E][WiFiClient.cpp:313] setSocketOption(): fail on -1, errno: 9, "Bad file number"
is most likely unrelated to "WS Disconnected"
is your board connected to WiFi?
@@tomasztarnowski4434 Yes it is connected to wifi
Hi Aaron,
try to compile the project with the debug flags:
in you platformio.ini file add:
build_flags =
-D DEBUG_WEBSOCKETS
-D DEBUG_ESP_PORT=Serial
and check what serial monitor returns
As of today 16th January 2024, this code is no longer working. I have spent all day trying to make it work but no response. I went ahead to copy your code base, but still won't work. I think something has broken with the aws serverless
Do you have any other solution? Need some help
Is it still not working?
@@Ares-vh9qz still same problem
@@linux1221 Damn... I tried contacting him but he's not answering. What is exactly not working with the aws serverless??
Oh man, u are to late, i need this knowledge 3month ago
there's more coming
maybe you'll find something useful :)
Sorry but for beginners this is complety crazy...😢
I can tell a full beginners video for me would be a titanic masterclass on the inputs and outputs of the tcp/ip layers of like 20 hours series
Me, a lazy dude, would have made everything a function used one time 🤣 just for beginners legibility
Or a full library 😂
I justo do a DHT temperature and humidity being see on an internet Pages acessível to all.
I give up! This is such a disastrous tutorial for a beginnner. It is ridiculously hard to follow with various components that you expect the viewer to know without ever specifying them.
After sinking about 5 hours in this video, trying to understand what you say and then solving all the errors you haven't mentioned including how you have to setup an AWS account, configure that information with your personal computer and so on.
At @42:16 , you just paste in code without every explaining where you got it from or how I can get it. Looking over your github repo, that code doesn't match as it contains addtional functions and leads to further several errors.
I still have multitudes of questions and errors. For example, when I deploy program, I keep getting erros like secret-key is not defined and etc. I would try to solve it but I don't even know where to start. Only by watching your other vidoes can I even begin to complete the puzzle.
As a self-learner with no knowledge of these concepts, you complete ruined the fun of the video. I have self-taught programming through online tutorials and I have never been left this confused and exhausted.
Instead of learning something new, I want to cry from frustration sinking so much time into a video while nothing to show for it.
What's most disappointing is that seeing your earlier video regarding hooking your esp32 to wifi and about platformio, I got so excited, but wasted my limited time on this 2 hour confusion fest.
This was a lot to know. Besides esp32, C and json, you have to know react, javascript and AWS. Thats a lot. One thing at a time then integrate them one by one.
I'm not sure that this video was geared towards beginners because of @noweare1's point
at least from what I can tell by looking for a solution like this, trying to control the device from anywhere in the world is quite an advanced concept as I can't find a lot of people that have done it from absolutely anywhere. Mostly just on local networks.
So if you are still into the IoT stuff I recommend starting a bit simpler than this. like trying to make it work with Low Bluetooth Energy.
