JN5189 OTA Upgrade Link Key Mismatch error

[Abdullah_Faisal]

Hello,
I am trying to OTA upgrade JN5189 using the JN-AN-1244 application node. Everything works fine with the zigbee2Mqtt but when I try to upgrade the MCU with a console application named Z smart systems 'https://github.com/zsmartsystems/com.zsmartsystems.zigbee' it shows a LINKKEY MISMATCH error.

Hello @Abdullah_Faisal

Hope you are doing well.

Just to clarify, you were able to upgrade the image via OTA successfully (for example, following the JN-AN-1244 Application Note Documentation, Chapter 6 OTA Upgrade, inside the App Note Doc folder), but when using "Z smart systems application" it is not working, is that correct?

If that is the case, could you please contact the owner/developer of that repository for more information on your inquiry?

Regards,
Eduardo.
