Hi ,

Follow the below steps (in dev kit P20 strip connector)

1. GND connect GND
2. VDD connect VDD
3. SWD IO connect SWD IO
4. SWD CLK to SWD CLK
5. In dev kit VTG is connect with VDD
6. In dev kit GND detect is connect with GND

thank you for reply. this nrf8122 module have only one VDD. if one VDD goes to other VDD in development kit. which VDD i have to connect with VTG in dk board.

Step 4 and 5 connect with in Development kit.

So we have to connect VTG on P20 strip connector to VDD on female connectors onto side & similarly GND of P20 strip connector to GND on female connectors onto side.

yes you are right. In P20 dont have GND it is GND Detect.
