Hi,
A typical reason for getting invalid object error is that the DFU image was not signed with the correct key. Can you confirm that the bootloader was built with your public key, and that the DFU image was signed with the corresponding private key?
If the above is not the issue, can you elaborate on the issue? Also, can you upload the log from the DFU master?
sir sorry... where i can get log. im new to this field
i created zip file but its showing invalid object

I see. Most likely that means that pre-validation failed for some reason. Typical reasons include:

this is the log file i got while trying to transfer the file
Hi,
I see. this means that pre validation fails for some reason, but we cannot see from the DFU master exactly what it was. You can either check RTT log from the debug bootloader to see exactly which check failed, or you can let me know in detail the configuration of the existing application (from when you generated the bootloader settings), and the full set of parameters you use when you generate the upgrade image using nrfutil. It would also be good to double check that you are using the correct key for signing the upgrade image (and that the bootloader was built with the corresponding public key).
i think creating zip file i made error. can u please give me the command prompt code for generating zip file for ble dfu
