Has anyone played with the Red to connect to AWS IoT instead of the AirVantage platform? Google was of no great help! Would love to see a tutorial for doing this. Any pointers welcome.
Thanks in advance
We use the Mangoh Red and have an option to connect to AWS IoT using certificates as they specify. We started with WolfSSL and created our own variant of MQTT based off the Paho async clients. Our solution is the result of many months of work and was not a simple exercise, but we have what I believe is one of the most stable and best performing solutions out there. We also have created a second security solution that uses the SIM card to generate TLS security credentials. That is our real product. Our solution is really a reference solution that weâve created for the automotive market and it includes a complete set of options including very low power operation, secure software update and our patent pending âquick connectâ solution. We can connect to an idle device in under 3 seconds without an active data session and without SMS messages.
Hi Thanks for the pointers. I had a look at the WolfSSL and there is a WolfMQTT. Wonder why you created your own variant and not use the WolfMQTT? There is also an example of AWS IOT. Did that work for you? Curious to learn more about your experiences
Hi,
You might also want to check this out as it uses AWS.

I am trying to use the AWS IoT SDK as an external build and linking into my app. I know if I build the SDK natively and run the sample test files it is working. But when I bring it into the Legato component I am getting build errors. If anyone can help me unlock would appreciate it

Iâm not sure what the problem is. Can you provide the source code for the project you are trying to build? If you can do that, then I will try to build it myself and try to work through any errors.
Hello David
Its not the same error any more, but I am still getting errors. Also Iâm not sure if I am using the DataServices call le_data correctly. Happy to receive your input. The file is attached

RedToAWS.zip (857 KB)
I have made some progress and now able to load the software on the board but coming across with some stability issues.
So seeing a number of issues here.
First I packaged the application within the system build. When I installed the Red system package, my app didnât show up with âapp statusâ. Also when I make clean the files donât get removed. Iâm guessing may be a sdef configuration issue.
Second, When I didnât see any activity on the log from the app, I then attempted to update the app, but the software informs me that this is already installed and wonât do anything more.
Third, I am attempting to load by the App certain certificate files. On my development environment this is easily detected, but when I try to replicate the same structure, it doesnât work. So I then try to specify a location on the target and it appears that application doesnât find these files.
Fourth I can see that the application doesnât like my attempt to establish a data connection. Iâm at a loss as to why and I canât get to the AWS servers.
Lastly I havenât been able to trace why the application is closed down.
Any suggestions on how to move forward would be most appreciated as I have exhausted all thoughts
If this is a tools/versions mismatch issue please help with links to matching software versions as I have spent the best part of 2 days trying combinations to get past various uid mismatch errors
I have highlighted the concerning areas on the attached log file.
Log dump 1812.pdf (267.4 KB)
OK I have progressed now and able to subscribe and publish but at some expense. I wanted to sandbox the application so that it has access to whatever data connection that already exist. For whatever reason the application doesnât like being sandboxed and doesnât show up on the app list. My other problem is that the app wont auto start. The app also doesnât like being a standalone App. That is it wonât start a data connection which is still puzzling me. Perhaps its because its a legacy App and not a Legato App, but I do get connectivity if I have another Legato App not sandboxed started before the legacy App. It means I have to manually start both apps now. Any suggestions to automate the process and also work inside the sandbox is welcome.
Hi @mohamid, can you publish a tutorial/wiki page so others can follow what you did? Other members who are interested might be able to provide more insights as well.
Hello chucklink,
I would like to know if you can share with me the code of the connectivity for the MangOH RED with the AWS IOT.
Thank you
Hi mohamid,
Can you share some tutorials/additional comments how to install this SDK on MangOH red?
