hi Bjørn Kvaale thanks you your testing ， but my PPK is not ok yet.

I think it is due to other reasons, I have done a test blew:

I just try to download the hex file to ppk use the nrfjprog.exe by a bat file ,It is not work,like the picture shows（DOWNLORD WRONG.png and DOWNLORD SETTING.png in the first comments）

Take a look at Chapter 4 in the PPK User Guide v1.1. Install python 2.7.12. Then, you'll want to install the latest version of pip like shown. Then, run the python_packages.bat file. Then, you can setup everything the way I mentioned in my answer (remember to set COM switch on PPK to DK, not EXT). Could you try running flash_ppk.py & then ppk.py & let me know if that works? If you take a look at the flash_ppk.py code, you can see that it is slightly different to what you have tried in your DOWNLORD WRONG pic. Also, have you downloaded all of the ppk files from here?
