How to specify device type and revision for application.dat file?

[la-ble]

I'm manually creating the .dat file for a DFU following the format specified in this document.

Where can I get the device type and revision values from to populate those first two words?

Does it make a difference whether I compress the folder containing application.dat and application.hex on a Mac vs Windows PC?

I've attached my application.dat and application.hex files for reference. The compiled hex is the example experimental_s110_with_dfu for the pca10028 dev board, but I still seem to be getting the error:

application.hex

application.dat

application.zip

There was a mistake in how I read the documentation. The user CAN specify if desired a device type and revision. This is not something specified by Nordic. It is something the user can choose to use.

The particular error shown above was because I was using an experimental variant of the OTA DFU firmware examples.
