After looking into error code it shows 'DFU_END_ERROR_UNAUTHORIZED'.

I followed procedure from here. Am I missing something here. Have flashed my application and trying to send blinky using DFU.

Please let me know if you need more things from me.

Hi. 

First of all, which version of the nRF5 SDK for Mesh are you using here?

Regards, 
Joakim

[Shubham]

nRF2 SDK for mesh 3.10

[Joakim Jakobsen]

Thanks!

Have you made any modifications to any of the examples you are using?

Regards,
Joakim

I am not using firmware from the dfu directory. I added dfu to my private firmware other things stays the same.

[Joakim Jakobsen]

Ok. 

The unauthorized error you are getting is very likely caused by your device having keys that doesn't match the keys of the DFU it is receiving. Either the DFU is sent without authentication or it's authenticated with the wrong keys. 

Best regards,

Thanks Joakim,

Understood, actually I was sending the wrong firmware, this firmware package was generated with different public key.

You can close the ticket.
