Hi Stanley,
Can you please confirm what version of MCUXpresso and the version of the SDK as well please.
Also what console are using to debug the example, the semihosting or uart? I ask this because the semihosting causes strange behavior in the application. You can check to see if this is the issue by flashing the application, stop the debug session and reset the board by disconnecting and connecting it again. Wait a minute or two while it connects then open your thing's shadow in the IoT Console.
You can find it under Services >> IoT Core >> Manage >> "yourThing" >> Shadow
If it is properly connecting you see the inital status of your shadow, as shown below:
If you see this then you can verify its functionality by manually editing the shadow state and change the "desired" Ledstate you will see the led turn on and off by doing this.
If you dont see this and it says something like this thing doesn't have a shadow then can you please show me what your thing's policy looks like as well as the aws_clientcredential_keys.h.
Please note: for your own security you can blur out or put x's at the beginning of your endpoint xxxxxxxxxxxx-ats.iot.us-west-2.amazonaws.com. You can also blur your key credentials the actual numbers are not important to me, but I would need to see how they are defined.
Best Regards,
Sabina
Hello Sabrina,
MCUXpresso: version 11.0.0_2516
SDK: version 2.6.0
The console displaying the messages is the one within the MCUXpresso IDE, not the UART
Under Services >> IoT Core >> Manage >> "yourThing" >> Shadow, it shows:
Shadow state:
{ }
I had the following Notification messages:
Mqtt connection lost. Reconnect. Error code: 8. AMQJS0008I Socket closed
Failed, please try again later.
Below is the policy document:
The 'aws_clientcrdential_keys.h' is also attached.
Many thanks for your help on this issue!
Best regards,
SL
Hi Stanley,
I've replicated the example with the same version you are using and had no problem.
So here is a couple of things to try as its possible something was not copied to project correctly.This is assuming you have made no other changes in the example than the two files you mentioned 'aws_clientcredential_keys.h' and 'aws_clientcredential.h'.
So double check the following:
In 'aws_clientcredential.h', make sure thay these four match exactly with your thing's endpoint and name, as well as your internet credentials.
In the 'aws_clientcredential_keys.h':
Download the keys again and copy them to the file.
First detach the current one.
Next click on creat certificate and download "A certificate for this thing" and "a private key" and click on activate.
Then "Attach a policy" & copy each key to the file again.
Last, I'd recommend to change the console to UART as I mentioned before the semihosting causes issues in the behavior. You can do this by selecting the example and in the Quickstart panel >> Quick Settings >> SDK Debug Console >> UART
Please try this and open your thing's shadow again, refresh the page if you still see the open brackets as you mentioned, to see if it changes.
Let me know the results.
Best Regards,
Sabina
