Yes, exactly.

you mean: disconnect the DUC and just let PPK2 run with power turned ON without the load?

I don't have anything else but Mac

I meant to say that the PPK2 isn't connected to any device such as the ESP32 that you mentioned earlier? I can tell from the picture you shared last that PPK2 is set to source mode with the power supply enabled. I was wondering if you can disconnect the PPK2 from any DUT and just let it be connected to your Mac and see if the current consumption is still high.

I will keep you posted but as far as I understand there is no specific request from you to me such as log or so? I am happy to help you guys to solve the issue of course as I need a reliable system for my "thingis" ;-)

Hi,

Ok, thanks for the description.

And you're still getting this readings if the PPK2 is not connecting to anything else than the Mac?

Please update this case if you have more new observation regarding this issue.

1- frequency: I did not use PPK2 since the last time we spoke - I just opened it today since then

2- when I restart the app all is OK (until next time)

3- I am not sure about voltage: I used today many values between 3.3V and 5V - when it happened I was at max=5V, the current drawn by my project is anything between 30uA and 300mA

Hi,

Is this happening with the same frequency as before? Do you see it after restarting the application?

Do you see it when you lower the supply voltage from the PPK2?

Hi,

Have you disabled usage statistics in the settings menu?

Just upgraded successfully, will let you know while using if there problem continues

However, do we need the bold lines? Do we need to be traced even while using the PPK2?

just asking ;-)

Hi,

There is a new update out that should address your issue. Can you see if you're able to reproduce the issue with v3.5.3?

regards

Jared

so far so good but it is too short to say

however, I see that the new version is much more different than I thought - see the screen from both versions - see how the new version extended the Y scale from 0, while 3.4.5 is excellent and the chart is where it should be - not from 0 but from min to max of the current it was drawn

RE: PPK2 showing crazy current even if it is OFF

zyghom — Thu, 24 Nov 2022 15:20:51 GMT

downloaded, testing

will let you know Jared

RE: PPK2 showing crazy current even if it is OFF

Hehe, I understand.

Could you try to downgrade the Power Profiler version by downloading the previous version here and follow this guide.

no, my last Windows experience was 10 years ago (and I don't miss Windows) ;-)

RE: PPK2 showing crazy current even if it is OFF

Jared — Thu, 24 Nov 2022 14:53:44 GMT

Hi Zygfryd,

Are you able to reproduce this with a windows computer and the same PPK2?

regards

Jared

RE: PPK2 showing crazy current even if it is OFF

zyghom — Thu, 24 Nov 2022 13:55:12 GMT

no, sometimes "eject" button does not make it working - so back to square 1: close the app, disconnect PPK2 from usb, start from the beginning and only then it works

RE: PPK2 showing crazy current even if it is OFF

zyghom — Thu, 24 Nov 2022 12:56:46 GMT

this issue is repeating all the time however I am not able to narrow down what causes it.

However, it seems that it is enough to restore the proper behaviour of PPK2 by simply clicking this button - no need to close the program and disconnect PPK2 from USB.

but the solution is for another few measurements and the problem repeats - I find it super annoying ...

RE: PPK2 showing crazy current even if it is OFF

zyghom — Thu, 24 Nov 2022 10:51:05 GMT

it happens again:

power is off, but the graph shows crazy values

and as you asked: I disconnected the load - no change at all

what I will have to do it is to eject PPK2, disconnect from USB, restart the software and it will be back good again

Ok, great.

Please notify me if it happens often.

hi Jared,

the crazy readings were not disappearing even when I disconnected ESP32, Only solved it when I closed the app and disconnected usb and then started new connection and application start.

But this was not the first time so I expect this to happen again and they I will follow what you said

RE: PPK2 showing crazy current even if it is OFF

Jared — Wed, 23 Nov 2022 13:49:50 GMT

Hi Zygfryd,

Could you disconnect the ESP32 from the PPK and only connect it to the Macbook. Are you still measuring unreasonable values when it's not connected to anything except for the Macbook?

Jared

Hi,

Can you share the revision and build code for your PPK2? You can read it of the sticker on the PCB.

regards

Jared

RE: PPK2 showing crazy current even if it is OFF

zyghom — Mon, 21 Nov 2022 14:17:50 GMT

o yes, of course

micro USB: "power plus data" connected to macbook

Vout and GND connected to my ESP32

PPK2 used as a source of the power for ESP32

no other pin connected on PPK2
