Exporting data from PPK

[Marcos1234]

Hello everyone!

As far as I've read in the manual, Power Monitor allows to export measurement data to file and use the for further processing. I'm using Power Monitor v2.2.0 in Ubuntu 18.04 LTS. I cannot see any button or something which allows me to export data to file. How can I do it?

Hi.

At the moment there is no support for exporting/saving the logs from the Power Profiler Application in nRF Connect for Desktop, where did you read this?

You could use the old logging firmware, the flash_ppk.py firmware to get logs to a text file.

If you wish to use the old Power Profiler Kit Software, which is not maintained anymore, there are the following requirements:

1. Python 2.7.12 (32 bit)

2. pyside version 1.2.4 (pip install pyside)

3. pyqtgraph version 0.10.0

4. numpy version 1.11.3

5. pynrfjprog version 9.1.0 (pip install https://files.pythonhosted.org/packages/44/60/26a2c5322670434d76a35456ed6d505bc7da58d2ce85fcc293ff34de1e17/pynrfjprog-9.1.0.zip#sha256=a24fdac8264760bc8506ee04d864985c46870ef4500e051c443f53f4aaa3f9e0 )

No other combinations of Python version or packet versions are supported. If you don't have these requirements then the python scripts might not work.

We recommend that the Power Profiler Application found in nRF Connect for Desktop is used instead of this old version, it will in the future also have a logging options. You should only use this version if you require logging to a text format, and that yet has to be released for the Application in nRF Connect for Desktop.

Best regards,

Andreas

I read it in the User Guide in "Key features" section.

"Export measurement data for post-processing"

So I've deduced it is about exporting to file.
