  • @summer: You need to provide some more information on:

    • The log you have when you update with Toolbox, try to find it using the nRFLogger app.

    • Which guide did you follow ?

    • Which application firmware did you use , how did you generate the .zip DFU package.

    • Have you tried the example .zip provided with the nRFToolbox app (inside NordicSemiconductor folder) ?
