PPK: Initialization failed - could not load calibration values, though they are shown in RTT

[erltot]

Last time I used it, it worked fine, it's been sitting in a drawer for some time since then.

When I tried to use it now, i get this error - even though I can read the output in RTT..

I've tried two different USB cables, one which was new and unused.

Any clues what is up here?

Hi Erltot, 

Could you let me know which PPK software version you are using ? 

If you are using v1.1.0 it could be a little bit out dated. 
The PPK software is now running on the nRFConnect platform. 
If you download nrf Connect application here, you can install the Power Profiler app. This app will flash the new firmware (v2.0.1) and can run on the GUI interface (not using python). 

We will update our website to point to the new software platform.

I was using 1.1.0

With new nRF connect it didn't respond at first, I had to clean the firmware and reinstall it but now everything works! Thanks
