I had the same issue. There is a workaround (downgrade to 3.7) here that worked perfectly and conveniently for me.

Hi,

[quote user="duxinglang"]that is to say, ppk is not connected to dk board, they are separate and independent operation.[/quote]

Is the nRF Current measurement pin (P22) on the nRF91DK open? If so, put a jumper on P22. If the P22 is open, it is not able to communicate with the chip from the JLink-OB.

Sorry, I did not make it clear. I use ppk to measure the power consumption of my client board actually, while the dk board is only used for program burning and simulation, that is to say, ppk is not connected to dk board, they are separate and independent operation. I suspect that Programmer V2.0.1 has some Bugs.

Hi,

For the Programmer app, you would need to remove the pin connection from PPK2 and put the Jumper back on P22. Then, the DK can be detected by the Programmer app.

I tried according to your way, now power Profiler can recognize PPK, but programmer still hasn't found my DK, it only shows that PPK is recognized, but JFlashLite can recognize and upgrade firmware normally.

Hi,

Try to turn off the DK and make only the PPK2 connect to the PC. After the Power Profile app of NRF Connect detects and connects to PPK2, turn on the DK.
