This article baed on "pca10040", nRF52832
example code path "examples/ble_peripheral/ble_app_uart"
board config file of this example located in "components/boards/pca10040.h"
and uart pin defined in this file, like this:
#define RX_PIN_NUMBER 8
#define TX_PIN_NUMBER 6
So, the KEY point of this example is uart character goes through PIN#8 an PIN#6
if you don't know where are they, see schematic of you board
I spend whole night to figure out why I can't see anything through my JLink uart
thats because my JLink uart using PIN#15 and PIN#16 as UART
after I changed my code to :
#define RX_PIN_NUMBER 16
#define TX_PIN_NUMBER 15
problem resolved(if nothing happened , try swap RX TX pin)

I can't find references to that N-LINK programmer/debugger online. Do you get it from Nordic Semiconductor?
Your problem obviously was that you don't use PCA10040 but some custom dev kit for some custom board. Therefore you should create your own header file for your HW. Anyway nice catch and if you would (finally!!!) identify what HW you have and place it to the article (preferably headline) you can save some time to many people coming after you!
my questions before
