I was plugging ppk mid way, so it was showing error .

Hi Ishika

Great to hear that you found a solution!

It would be interesting to hear what the problem was?

Either way, I will close the ticket.

No I only have nRF7002dk.

I will once try with another PPK2 kit and get back to you.

I tried with another ppk, it is showing same result.

Getting 0uA and when connecting in opposite polarity I am getting some, 2.6uA. So is this setup issue or code issue? or issue with nrf7002dk?

also I looked into this,

when connecting according to your quoted message, I am getting 0uA and when connecting in opposite polarity I am getting some, 2.6uA, like attached below.

can you run Wifi: shell example in v2.5.1 of SDK and tell me the readings you are getting on your end?

I think I have some issue in the code, so just want to confirm from your end.

So there should be some reading, but in one of the thread it was mentioned that if we connect in opposite polarity it would hurt ppk2. So I think because of this that it is showing 0uA.

I see the same warnings on my side, I don't think they are related to the issue with the PPK.

Do you happen to have any other Nordic kits available, such as an nRF52 based kit?
It could be interesting to try and use the PPK2 with some other kit just to check if the issue is related to the nRF7002DK, or to the PPK itself.

The screenshot you shared earlier indicates some PPK issue, since even if you connect it the wrong way you would expect to see some noise in the PPK readout. In yoiur screenshot it looks like the PPK2 is reading exactly 0 constantly.

Also, there are 2 warnings in the code

Hi,

I tried with Wifi station example, and made the setup as you have showed. The code is running but there is no output on power profiler side.

Hi Torbjørn,

Version is 1.0.2

ovrebekk — Mon, 19 Feb 2024 09:12:03 GMT

Hi Ishika

I mean the version of the kit itself. There is a white paper label in the middle with the name PCA10143 and a version number underneath. I can see it in your picture, but it isn't sharp enough for me to see the version number and production code.

Best regards

Sure will test with wifi station example and get back to you.
Version of nRF7002dk, didn't get you, are you asking host mcu?

Make sure to do a full power reset of the board after flashing the new code, to ensure a full reset of the system.

My measurement setup looks like this:

And the PPK plot looks like this:

Which version of the nRF7002DK do you have?

Ishika123 — Fri, 16 Feb 2024 11:02:13 GMT

Hi Torbjørn,

I tried by connecting as you said in the link using step5 and 6. It didn't work.

Also how you created application and which version are you using for measuring the current?

I am using wifi shell example with 2.5.1v of toolchain and sdk.

Just let me know when you have been able to test it.

Hi Ishika

It is very strange that the board doesn't work for you, when connected in the same way.

Could you try to use the PPK in source mode instead, as described here?

The link I sent assumes you have two PPK2 kits available, but the procedure will work with a single kit also, you just need to keep the jumper on P22 in place.

Following this method you should use the PPK2 in source mode, and ensure you supply a voltage in the 3.0-3.6 range.

Best regards

Ishika123 — Thu, 15 Feb 2024 04:38:21 GMT

Hi Torbjørn,

Now the error changed and it is showing bus fault error. After we connect PPK2 to P23 of nRF7002dk, and output of PPK2 shows DUT on, then if we pass any command it throws bus fault error.

Also, first we create application and then create west workspace or vice versa?

Ishika123 — Tue, 13 Feb 2024 10:33:39 GMT

I tried connecting as told by you, but it is not showing any output ( 0uA). But when connecting the opposite way it is showing 1.16uA, attached the image below.

Also just to verify if I have not made any mistake while setting up application (I have used wifi/shell on SDK v2.5.2, using nRF connect for VS code), could you please share any link.

I just tested it on my end and can get it to work without any issues.

Looking at your picture it seems you might have the two pins from the PPK mixed up. Can you verify that VOUT on the PPK is connected to the arrow pointing inwards on the DK (the pin closer to the Debug Out connector) ?

Yes loaded ppk2 and output showed DUT on,

connected ppk2 (Vin and Vout ) to P23 of nRF7002dk.

Have you configured and started the PPK2?

Could you show a picture of your setup, showing how you are connecting the PPK to the nRF7002DK?
