I will start&nbsp; fresh today with SDK 14.2 and report here, thank you.</p><div style="clear:both;"></div>RE: DFU on SDK v14.0 or v15.1 question, doing everything by the book but can't get it to work.https://devzone.nordicsemi.com/thread/157095?ContentTypeID=1Tue, 13 Nov 2018 13:23:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:553748c8-bd30-40eb-954b-3602448821b5Hung Bui<p>Hi Oleksandr,&nbsp;</p> <p>I&#39;m sorry&nbsp;to hear that you have trouble when testing our DFU solution.
