Thanks ,I solved the problem. In fact, it is necessary to select " DUT Select "instead of Dk at SW2

Oh sorry, I read a bit fast and didn't see you were using a PPK. I'm not sure how exactly the device works so I'll let someone with more experience answer.

its necessary to add a 10 ohm resistor ?

Hi, when you remove the jumper on P22, do you replace it with an ampere-meter or a 10ohm resistor on R6 ? Because looking at the schematic for the nRF52 DK, if you cut SB9 and don't replace it with anything, I don't think your nRF52 is powered at all (VDD_nRF is just disconnected).

hello @ haakonsh ,

I don t think so, because when I use a jumper in the P22 pin, the program works.

i don t have any error when i launch the ppk application .

so i didn t see where s the issues ?

Can you help me .

thanks

Ahmed

Hey Ahmed,

You might have acidentally flashed your application to the PPK instead of the DK. The PPK uses an nRF52832 that communicates with the PC application through the DK's on-board debugger (SEGGERs Real Time Terminal).

I need you to launch the PPK application in nRF Connect and tell my what error code you get.

Cheers,

Håkon.
