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)

Now I will set up this utility on my cellular and join the TP-link modem to the keyboard to pass the contemporary in it. If it will really phrase then I will begin the typing to make Essay Help UK book entire earlier than the time of post day.
Thanks. You’ve helped make it clearer for me! spanishto-english.com/spanish-dictionary
Now I will install this application on my mobile and connect the TP link modem to the keyboard to pass the current in it. If it will actually word then I will start the typing to make bestessays book complete before the time of publish day.
Thanks for this detailed post ! But it was initially made for the SDK12.3 if I'm not mistaking? It's not working with the 14.2, for example, there is no ble_evt_dispatch function anymore so maybe some code are missing. I got stopped by a vector catch (HardFault_Handler) at the SVCALL for the sd_ble_gap_device_name_set. Do you have an updated version of your tutorial that could help?

I can't find references to that N-LINK programmer/debugger online. Do you get it from Nordic Semiconductor?
