This tutorial series is nothing less than a Gold mine....the more you dig the more you explore...... amazing work.....please keep posting such videos......🎉

[@Cherupakstmt]

This is a gold!. Thanks for awesome presentation.

[@jfr7038]

@architecturebytes, I'm sure I'm missing something. Being a newbie, Can you please clarify whats the purpose of having location service, event bridge and additional Lambda if the first Lambda function directly sends the data to DynamoDB table?

[@ArchitectureBytes]

While you could store location data directly in DynamoDB, Location Service offers specialized capabilities for managing and processing location data, including geospatial data storage, spatial queries and calculations, geocoding/reverse geocoding, routing, map visualization, geofencing (trigger action if device enters or leaves a certain area) - which are very useful for Location based applications. This demo does not demonstrate All the capabilities of AWS Location Services.

It keeps showing "Failed to load resource: the server responded with a status of 403 (Forbidden)" in browser for loading index.js & simulator.js for index.html & simulator respectively.

[@Seven-ky6nq]

btw I set rules and policies in us-east-1, and my default region is ap-southeast-2, will it be affected?

[@ArchitectureBytes]

Please see the Readme file in the github repository linked in video description. Just check if you missed any configuration or step.

"Error sending location data: An error occurred (AccessDeniedException) when calling the BatchUpdateDevicePosition operation: User: arn:aws:sts::{Account}:assumed-role/FleetLocationSave-role-pboyo8hn/FleetLocationSave is not authorized to perform: geo:BatchUpdateDevicePosition on resource: arn:aws:geo:ap-south-1:{Account}:tracker/FleetTracker"
I am getting the above error while simulating the location data from FleetLocationSave Lambda function.Can you please help?

[@ArchitectureBytes]

The lambda function must have a role that has permissions to write to tracker.
Kindly see Readme on github repo - for details.

[@user-ev5sn8hs7e]

I am getting 403 forbidden error when "send location data" button in simulator.html .do we need to add other authentication for that?

[@ArchitectureBytes]

Have you updated the IDENTITY_POOL_ID, IOT_ENDPOINT, TOPIC, REGION correctly in web/js/simulator.js? Please check the same.

[@user-ev5sn8hs7e]

@@ArchitectureBytes yes updated .

[@ArchitectureBytes]

​@@user-ev5sn8hs7e
Pls check if Identity Pool is created with 'guest access' as shown at 8:10 onwards along with a Role that has appropriate permissions (see Readme on github repo for details ).

[@zoomcam7706]

hi
can u please integrate this option in our fleet management software?

[@ArchitectureBytes]

Which software are you referring to?

[@zoomcam7706]

datbase is sql server.I can explain to u table structure@@ArchitectureBytes

[@ArchitectureBytes]

The tutorial should help you integrate.

[@jfr7038]

Awesome tutorial to the point! Thanks. For me, all went well except the index.js is not able to make connection with websocket it looks like. socket.onmessage() is not executing . Still in the process of troubleshooting. but just wanted to check if anything i should look for
here is my test code by removing other pieces
socket.onmessage = (event) => {
console.log('Message received:', event.data);
};

[@ArchitectureBytes]

Please see the Readme file in the github repository linked in video description. It has necessary instructions.

[@jfr7038]

@@ArchitectureBytes Thanks, As a newbie, it took sometime to figure things out on how to setup right permissions to those lambda function. But, All looks good. Its works great . Thanks again. this gives me a overall idea about how to leverage AWS services to proceed further with my POC.!!!

[@jfr7038]

Im just wondering if you have any insights / videos on sending real device data to Aws IOT and tracking its location through the similar architecture?>

[@ArchitectureBytes]

@@jfr7038 You would use similar architecture for that. You can also see the IoT Playlist on this channel. The video description has a link to that.
