Thank you for reporting this, I have reported the bug internally.
As with the last one, I am not able to give a time estimate on when this will be fixed yet.
But I will let you know when I can give you more information on the issues.

Regards,
Sigurd Hellesvik

Hello.
Thanks for your reply.
Understandable. Thanks for your help.

I also have another issue, i am unsure if reported by anyone.
I made a video where i showed what is going on:
https://youtu.be/0r0edfkOH6c?t=525

In a nutshell. The output buffer is not cleared when starting a new measurement which gives the user incorrect measurements and a big spike which i initially thought was some capacitors charging up

I found the guy who wrote the firmware for the PPK2.

The PPK2 does not have functionality for remembering DUT state after Serial disconnect.

This have been added to the list of things to be done, but we can not give a time estimate on when it will be added as functionality.

Good to hear that you are able to figure out some way to do it better in the meantime!

Hello.
Thanks for the update, sorry for not replying.
I've figured out that it was not my device that timed out so for my testing this will work.
I still would highly prefer being able to keep the power supply powered opon closing the Software/serial port for debugging but it is not as high a priority as it was when i thought the device timed out and reset

Works really well for my test setup until now!

Hello

I still have gotten no answer from our developers.

I hope they answer me early next week.

Ah, I see your issue.

The PPK2 firmware does only supply power if a serial connection is upheld.

I will ask our developers if there is any way to fix this. I hope to get you an answer by end of tomorrow.

Hello,
I am already using this library.
but in my case the power supply turns off and resets(voltage is 0.8V when opening SW) by itself after some time being inactive or you close the communication.

Assuming you are using the PPK2 with https://github.com/IRNAS/ppk2-api-python, use:

ppk2_test.toggle_DUT_power("ON")

ref example.py#L37
