Getting Started with Amazon AWS IoT Core using ESP32 || Creating Thing, Policy & Certificates

[@HowtoElectronics]

For those who are working currently with the latest aws version, there is an update on the Resource ARN part. Replace resource ARN path with * sign. Replacing the path with * will simply allow everything.

[@WhiteLemon_Official]

thank you! great help!

[@simhadripatapanthula9091]

yes . i tried that but what data i give in subscribe data topic

[@danieltrivino2935]

Great video and excellent explanation Have a question about the certificate. Do I have to update the code on the EDP32 to make it work?

[@HowtoElectronics]

Yes update all the certificates

Super projects with AWS, Graet explenation, THANKS

[@djom20]

Amazing video, I love it, Thanks a lot for this demo. I only recommend updating it with the new versions of AWS

[@abdussami4500]

Do i need to open aws to check everytime or can I get a notification or something

[@hacker6695]

Hi.. i am not able to create policy. Its giving error "Policy document is Malformed: The following resources are invalid" what could be wrong ? its not showing Resource arn.

Thank you for the video! but, can I do the same with a DS18B20? and how? which are the libraries I'll need? Thanks

Hi, Please make tutorials on Device provisioning service (DPS) using ESP32 & AWS.

[@SteveOnIoT]

Hi, you have a subtle problem in your code which could lead some students to problems. You declare your byte buffer as "char jsonBuffer[512]". That won't work by default. The MQTT payload size limit is hardcoded to 128 bytes in the MQTT library you are using. IF you want to use a larger buffer size for a bigger payload to publish then you would need to change the constant in the relevant header file in the MQTT library. If the user's payload exceeds 128 bytes in your 256 byte buffer, the device will connect but no payload will be delivered to AWS IoT Core

My esp32 board is hangging at Connecting to AWS, could you help me out? It cannot connect to AWS IoT Core, only display Connecting to AWS......

[@jeiffer777]

having the same problem would like help as well if anybody could find a solution

[@edb5031]

Same Problem here too, mine is connecting to the wifi but not AWS. So presuming I've initialised it wrong somewhere. If anyone had this issue and subsequently managed to fix it, let us know 🙂

[@SteveOnIoT]

Usually this is caused by incorrect certificates. First step is to check the monitor tab in AWS IoT core to see if your device is even pinging aws, if not its likely a bad endpoint, also make sure your certificates are created in the same region as your current IoT Core console. After that make sure you have attached a policy to your certificates. Make sure your certificates are activated. Finally make sure port 8883 is not being blocked by your network admin.

[@PabloDiaz-lm2it]

@@SteveOnIoT oh my god you are a god send. You and the author of this video. Thank you!!!!!!!!

[@bennid861]

Nice video, as you said this course is for beginners, is there also a version planned with more advanced stuff? Like how to create some kind of middleware between your devices and aws, to make sure no data are lost in case of missing internet uplink. What do you think about the approach two use mqtt in your local network and a subscriber which will publish all events to aws, with this in place you could also use other devices (with mqtt support)

[@HowtoElectronics]

We will be making at least 10 videos related to AWS IoT core. Just wait for updates and subscribe to our channel.

[@SteveOnIoT]

Thats what AWS Greengrass is for. Also don't reinvent the wheel, AWS shadow device services handles holding last known state of device with updates ad updates/accepted

[@FredFlintstoffel]

It seems AWS does not have the same user interface anymore and I am really struggling to get esp32 connected to IOT Core. Any updated explanation?

[@FredFlintstoffel]

Nevermind, it seems it is just superficial menu Changes, will try again

[@FredFlintstoffel]

AWS connection just keep trying and not connecting, I did follow all steps to the letter. Any Advice?

Can you tell how to send these data to react web page ?

[@DANIELELMERPARADOSOSA]

When I send data at 30-second intervals, only the first piece of data is sent and no more data is sent afterwards. But when the delay is set to one second, the data is sent normally. Why does this happen?

[@ayan.debnath]

Great tutorial, Beautiful Voice.

[@dmaria9931]

Do you know what can I do if from AWS MQTT test is not possible send the sub message to the ESP?

[@SteveOnIoT]

You have a subscription option on your device in most ESP sketches. Simply subscribe to a topic then use a republish function from lambda or republish directly to your topic on IoT Core

I can not connect to AWS, where should I save the secrets.h file, And should I save the secrets.h file like as it is (all small letter) or must the s be a capital letter S. as on your discription?

[@SteveOnIoT]

Secrets.h is a separate file to add into the project, so your Arduino screen would have two file tabs (Arduino-->Sketch-->Add file) . Capitalization doesn't matter just keep the name consistent between the invoking file and the header file.
