Configuring nRF5340 for RF measurements

How to configure nRF5340 for RF measurements. which programs can be flashed to the device to get 100% TX and 100% RX and measure the RF parameters

Hi, As you can see here it does not make sense to measure both VDD_HV and VDD."

By default, the high voltage regulator is configured to source external components from the VDD pin. To save power this feature must be disabled. For details, see High voltage mode."
Is the device running in HV mode? Also, is this a custom board? I'm not sure that you would gain anything to measure the current consumption since if it is a custom boards you it can be hard to correlate power consumption with RX effect.

Hi Runar,

What did you mean by custom mode I'm using a nRF5340 DK and putting it into modes like advertisement using nRF connect in V S Code. 

So my question here is at that time, which of these rails(VDD & VDD_HV) can give the chips current consumption at these modes.

I was supposed  to write custom board. Since you are using the DK we have guide for current measurement here. 

I would also suggest to upgrade to a newer version of NCS for doing the radio test sample. I'm not sure what is going on v2.3 but I have tested a few newer versions and they all build.

Hi Runar,

I've updated the NCS version now but I'm facing these error on building an example,

this issue is facing in Both NCS versions, v2.3 and v2.5.2.

please help me resolve this.

Hi Runar,

Here the documentation is discussing on how to carry out the measurement right?

I'm asking you which number to be taken into consideration as the chips current consumption in these different states.

Hi 

just so that we are on the same page. You are trying to build the peripheral_lbs sample now? 

Could you update the toolchain so it aligns with the SDK version, do a pristine build and if it fails, post the log output. Just copy paste the log from the terminal and go back here, insert -> code and past it

Regards

yes I'm trying to build peripheral_lbs sample.

there is no toolchain of v2.5.2 available, I tried downloading tool chain v2.4.3 but it is failing to update.

what do you mean by printine build?

to create the project again? 

Reagrds,

Arun

That sounds very strange. You should be able to see multiple newer toolchain versions then 2.4.3, could you post the error message you get?

 

If you select the round arrow you do a pristine build and rebuild the entire project, however it is not worth doing until the toolchain and sdk version is aligned.
