Zigbee FOTA update won't apply

[pjbuntinx]

Hi,

I am currently developing a custom Zigbee end device with support for FOTA updates. My FOTA seems to work (all data gets transferred correctly) but the update won't apply. The device just restarts and still has the same MCU boot version. For testing FOTA, I am using the Zigbee Light Switch example. Please check my Wireshark capture and see if anything is wrong with the transfer (header, subelement header...). The secur key of the coordinator I am using is: "9d557f5dac6d327963c2d984083b9e7d". 
I am using NRF connect in VS Code with SDK version v2.5.2.

Thanks in advance!

Best Regards,

Pieter-Jan Buntinx

Hello,

After reviewing the logs, I suspect the issue might be related to image signing. Have you followed all the steps mentioned on this page? Ensure that the firmware image being sent over OTA is correctly signed and validated before the update process.

Kind regards,
