Hello,

I'm not sure what's causing the INVALID OBJECT here, but you are using a bootloader set up for the nRF52832 device. You should use the bootloader_secure_ble\pca10056_debug with s140 5.0.0-2.alpha instead if you want to test DFU with your preview kit.

Note that alpha release of the softdevice must not be used in production. See compatibility matrix below for supported combinations of Softdevice, SDK and silicon revisions.
