FreeRTOS OTA upgrade abort and restart,

Partners & Sponsors AWS
1

I have implemented the FreeRTOS OTA on my STM32 device. Generally it works fine, but sometime, maybe 1 in 10 case, I found OTA upgrade abort and restart it.
may I know what is the reason behind it and may I know how to resume it not restart it?
as I have already download large data, if network or anything wrong, it good to resume not restart.

Hello,

The OTA demo should suspend and resume if a network error happens during the download. From the part of logs you shared it seems the network was disconnected the agent was suspended and resumed after the the device reconnects. Can you please confirm if the same job was received and not the next one in the queue and if the previous job was aborted ?

It will be great if you can upload the complete log by removing any sensitive information that you want to hide.
