Hi,

can you give any insight into why this is so? I have just encountered a similar issue whilst working with DFU - UART and building the blinky example. Actually ends up in exactly the same place in that I get INVALID OBJECT when trying to run DFU.

Windows 10, nRFgo Studio v1.21.2.10, SEGGER Embedded Studio 3.50, GNU Tools Arm Embedded 7 2018-q2-update, nrfutil v3.5.1, nRF5_SDK_15.0.0_a53641a, nrfjprog v9.7.1, JLinkARM.dll v6.34b

That seems to have helped with DFU packing, thanks.

Unfortunately I'm still not able to perform OTA update (get INVALID OBJECT when trying to run DFU). Probably that's a different issue.

Which SDK version are you using? I am guessing you used the blinky example from the peripheral folder without the softdevice, right? If you used the peripheral folder, could you try using the blinky example that includes the s132 softdevice (inside s132 folder, blinky_pca10040_s132) & try the OTA-DFU again? That should hopefully make it work.
