No J-Link device found

[Beginner]

Hello, I am using PCA10040 and sdk12.2.2. I am trying to load ble_app_template code. But when I try to flash my code in pca10040 I am getting error as "No Jlink Device found". I am able to see my dk in device manager as "JLink CDC he UART Port(com14)". I am getting com port still I am unable to load the code.

Have you flashed the softdevice to your nrf52? You can do this by installing nrfGoStudio. When you open nrfGoStudio, find the device manager section -> nrf52 development boards -> click on the Segger tab -> press Erase all -> press Program SoftDevice tab -> press Browse ... -> find softdevice under SDK folder -> components -> softdevice -> s... (choose the correct softdevice) -> hex -> choose the hex file. Then, press the Program button. Then try flashing & downloading your code again. Hope that helps!

Have you also checked that you have installed all of the required software? See the "nrf5 Getting Started" tab -> "Nordic Tools & Downloads" in the Nordic InfoCenter.

Hope that helps!
