Hi Alessandro, You can confirm only the running image, so you need to reboot your board after upload, and then confirm if it works ok. If you reboot again without confirming the image, it will be reverted back to the old one.
For a disconnection error at the end, could you try getting btmon logs (on linux) so we can see the reason of disconnection?
