It's all right. DFU works again.

I tested on smartphone and desktop PC with nrf connect. It's only space introduced by windows script that is not supported by python parameters, that corrupted zip file.

Thanks for your quick support

Regards,

Cedric

I solve problem by adding :~0,-1 between %% of variable path

Hello

For the "space" caracter added to file name, I think I find the reason.

I run batch script on windows. I write batch with parameters like path of hex file (because I have several hex to manage). In my batch, I verify each command by an echo, and all is right.

Then, these parameter have a native "invisible" space on variable (find in forum cmd / batch), but when use by windows, the "space" is automatically removed, then I not see it (ex with echo).

However, if the variable is passed to nrf_util, the space is conserved because it is a python script and not a windows management. I supposed the file extension (hex) is replaced (into python script) by BIN and DAT extension and the extra space is keeped.

So,

- in .json file, there is space because it is generated by python script

- in windows file system, the space is automatically removed ! (I test it by adding manually space, it is not possible, windows remove it immediately).

Regards

Cedric

Hello,

Yes indeed there is a space after .bin and .dat in .json file (I had indeed not seen it), but the files do not have spaces, it is very surprising.
I manually deleted the spaces and re-zip.

It doesn't work any better, but the file opening error is gone.
I therefore have 2 questions:
- where does this space come from because the script only has the .hex and the .zip as input (and there is no space), the .bin and .dat are not managed by me (but directly by nrf_util)?
- even if I remove the space, the download does not start, what can happen? In the log, the message is "[DFU] wait(600)"

If you open the manifest.zip file inside, you can see that the file names contain a space at the end. Check if your script does not contain any spaces there, you may also try to removing the spaces manually and replace the manifest.json file with the modified one.

{
    "manifest": {
        "application": {
            "bin_file": "Periphs_nrf51822_xxaa.bin ",
            "dat_file": "Periphs_nrf51822_xxaa.dat "
        }
    }
}

Hi Milleret,

Could you please clarify, can you open the .zip file you created using nRF Connect on Android or nRF Toolbox on Android ?

Please attach the file you create here as well.
