Hi,

Currently I am using TICC3220SF along with AWS-FreeRTOS example demo project downloaded from AWS.

While downloading OTA-JOB document, I am getting the same duplicate JOB document 2 or 3 times.

I understood that, this behaviour is because cloud is expecting Ack from the device (as enabled QOS1 for prvSubscribeToJobNotificationTopics),

Ack is missing due to network issue(testing under slower network).

Whenever this issue occurs, OTA task is getting aborted and reporting JSON parse error to the cloud.

**Device side Error :** _“Superfluous report of current job”_  
**Cloud side error :** _“error occurred during JOB Document parsing”_

If I make device side code changes QOS1 to QOS0 I am able to resolve the issue.  
I wanted to do work around to avoid the duplicate job and continue upgrading the OTA without aborting.

Please help me to resolve this.

Please find the following logs for more info:

HI pvyawaha,

Thanks for your reply,

I am using SDK _ **SimpleLink\_CC32xx\_v2\_10\_00\_04** _ (OTA : Amazon FreeRTOS OTA V1.0.3).

There is no custom changes, I am using AWS-OTA Example code.  
Creating OTA task _**prvOTAUpdateTask()**_ and checking OTA update by _**OTA\_CheckForUpdate()**_.

Below API is causing the issue (eOTA\_JobParseErr\_BusyWithSameJob):  
_**prvProcessOTAJobMsg()**_

Regards,  
Suresh

Hello,

If you are using MQTT protocol ( which is only supported at this time for control messages ) you do not need to call the _**OTA\_CheckForUpdate()**_ as you are already subscribe to the job notification topics. Can you try running the demo provided and check if you still receive the same error?

Hi pvyawaha,

Thanks for your response and support.

Device operates over battery and goes to hibernate mode regularly, Due to application requirement needs to perform _**OTA\_CheckForUpdate()**_.
