How use to Power Profiler Kit and nrf52840

[sema_tufan]

Hi,
I am working on sample projects on the subject "proprietary_rf" which includes the nRF5_SDK_15.2.0_9412b96 sdk. I updated the codes according to my own project. Finally, I want to make some measurements using the Power profiler kit. I have 2 piece nrf52840dk. I installed the power profile kit on nrf52840dk, which I encoded as rx. You will see it in the photo I uploaded.Then I opened power profiler from nrf Connect application. The receiver is connected nrf52840dk and chose it. I press the button from the transmitter. The receiver works, but no measurement appears on the application screen. I want to measure current. Or what can I do. Can you help me?

Hi Sema, 

Have you cut the solder bridge SB40 on the PCA10056 as instructed here (and in the PPK user guide) ?

I have reviewed the PPK user manual. I get an error when connecting to nrf52840dk with the nrfConnect program.  

"Error while probing devices: Error occured when get serial numbers. Errorcode: Could not execute the function due to too many calls in line (0xe)". The led was on when I installed the first ppk. Then when I put it on, the led did not light up. I wonder if ppk is broken?.

Please take a screenshot when the issue occurs. 
Have you made sure you flashed the firmware for the PPK  ? 

You didn't have the issue last time when you posted the question ? Has the PPK worked and you managed to measure current before  ?
