Zip file format for DFU on iOS nRF Toolbox

Paul

I am having some trouble sending DFU to my development board through the iOS app.

When I prepare a zip file for the nRFToolbox app, I include the .dat and .bin files in a zip file. I transfer this zip file to my iOS device. When I load the file through the nRF toolbox app it says "DFU application.hex not exist inside selected file demo.zip" [sic].

I downloaded the iOS nRFToolbox source and found a few of the example zip files - "hrs_sdk7_1_bin_sc.zip" - if I manually upload this to my iOS device I can transfer it using DFU to my board. In other words the demo zip works.

But. If I unzip "hrs_sdk7_1_bin_sc.zip" and rezip it (using either Mac or Windows) and repeat the process I can no longer send the DFU and get the same "DFU application.hex not exist inside selected file nordicExample.zip" error as above. Because the contents of the zip file is identical to the demo zip and the only difference was that it was extracted and re-compressed, I am lead to believe there is something in how this is being zipped up that is causing the iOS app to not parse the .bin/.dat file. Also given that it is looking for a .hex file in the error message makes me think this is a generic exception.

I am using nRF Toolbox 1.8, released a few days ago in the App Store.

Please advise.

    I am using nRFToolbox version 1.8, updated April 17, 2015, downloaded from the iOS App Store. Whether or not this differs from the repo version of nRFToolbox available through the Nordic website, I couldn't say.

    I see the same issue with your attached HRS_S110_V7.zip file. Sending it straight over to the app works fine. Uncompressing and recompressing it causes the app to fail with the same "application.hex not exist inside selected file HRS_S110_V7_Mac.zip"

    I am reattaching both zip files. The original you can see in a hex editor is identical to yours. My uncompressed and recompressed version using OS X's built-in zip tool yields a different zip file. When both files are extracted, the contents of the .bin and .dat files are identical when doing a binary diff. Attaching files in the following comment due to character limit.
