In the SDK example , lpc54018iotmodule_aws_aws_shadow_wifi_qspi_xip , I see some errors as below :

>>>>

The SDK is :

The IDE is :

MCUXpresso IDE v10.3.1 [Build 2233] [2019-02-20]

Once it fails , it will never be able to publish again. The only way to fix it is to terminate the debug session and start over again from beginning..

>>> Adding MQTT Fx Client

My AWS iot thing is OK.. I can see the shadow update message from Mqtt Fx Client. As you can see from the attached log , the errors happened after many successful publishes. I could duplicate the error if I re-run the program. The time to get the error message is random. Sometimes it runs more than one hour to show the error , sometimes errors come out in 10 minutes.. Anyone see something like it ??

Thanks

Hello Rick,

This behavior seems quite strange. I dont believe that there should be an error with the actual connection, because generally when there is an intermittent signal it will cause an error, but should try to reconnect again.

I will try to reproduce this error with the earlier version of MCUXpresso.

However I am currently using MCUXpresso 11.0.0 and the SDK version I have is 2.6.0. Could you please confirm the SDK version you are using as well?

Also could you provide a small description of your process, what it is being updated?

Best Regards,

Sabina

Hi Sabina,

Thanks for the reply. The SDK is 2.6.0(228 2019-06-04) : SDK_2.x_LPC54018-IoT-Module. The MCUXpresso is MCUXpresso IDE v10.3.1 [Build 2233] [2019-02-20]. This example is to update the AWS iot shadow state every 5 seconds:

{"state":{"desired":{"Shd-IOT-0":"red"}},"clientToken": "token-56156"}

{"state":{"reported":{"Shd-IOT-0":"red"}},"clientToken": "token-56360"}

The shadow Document :

Shadow state: ( from AWS console )

{   "desired": {     "Shd-IOT-0": "red"   },   "reported": {     "Shd-IOT-0": "red"   } }

I could see the update message from MQTT fx and AWS iot console. The messages are correct. However , as you could see from my post , the LPC54018 iot module will run into errors and not being able to publish message anymore.

Thanks

Rick

Hello Rick,

I've gone ahead and tested this from my side and so far I do not experience the same behavior as you.

I am working with MCUXpresso 11.0.1 and the same SDK version 2.6.0.

I have connected to my AWS thing and are able to see the shadow update properly as you mention. However I have let this run for over an hour and have not seen the same results as you.

Are you using semihosting or uart as your serial console? The semihosting console has been known to cause issues in the execution of applications.

Does this happen in a debug session only or also without the debugger?

Were there any modifications made to the example?

I possible I would recommend to update your MCUXpresso IDE and try again. Let me know if the results are the same.

Best Regards,

Sabina

Hi Sabina,

Thanks for checking. I will try MCUXpresso 11.0.1 .

I use semihosting :

[MCUXpresso Semihosting Telnet console for 'lpc54018iotmodule_aws_aws_shadow_wifi_qspi_xip JLink Debug' started on port 58215 @ 127.0.0.1]

I did not modify the example except the "clientcredential.h" ..

Thanks again...

Not a problem. If you would like to test using the UART console. You can change the settings of the project by clicking the project itself. Then in quick start panel on the bottom left corner you will find quick settings-> SDK Debug console-> uart console. Rebuild and run your project.

Then open your preffered serial terminal such as teraterm.

Sabina

Hi Sabina ,

I follow your instruction to test using the UART console . The program run over one hour without issue. Thanks.

I do not use Teraterm. The MCUXpresso IDE has a terminal tab. I select /dev/cu.usbmodem on the setting- >serial port then I can see the output :

12525 6984367 [ShDemoUpdt] Performing Thing Shadow update.
12527 6984402 [ShDemoUpdt] [Shadow 0] MQTT: Publish to operation topic succeeded.

12530 6989128 [ShDemoUpdt] Performing Thing Shadow update.
12531 6989161 [ShDemoUpdt] [Shadow 0] MQTT: Publish to operation topic succeeded.

Thanks for your help...
