Blinky Example fail

[Mehmet Nuri]

Hi, i have just bought a NRF51 DK. I have tried to run the precompiled Blinky example. I have first installed NRFGo Studio. I connected the board. In NRFGo Studio, I selected the board. At right panel, Program Application tab, i have selected the .hex file and pressed the program button. I have pressed the verify button to see if the program installed. It has verified but no led on the board blinking except LD5(close to on/off switch). Is there something wrong with the board or did i do something wrong ?

Hi,

Are you using the hex file called blinky_pca10028.hex located in the folder SDK_folder\examples\peripheral\blinky\hex\ ?

I have tried them all. none worked. there are 3 files named blinky_pca10040.hex, blinky_pca10040_s132.hex, blinky_pca10056.hex. User guide for 51 DK does not specify any one of them. I assumed they all works in different ways.

Since you only have these 3 files, it seems that you are using a SDK version that does not support the nRF51-DK.

The latest SDK version that supports the nRF51 is SDK 12.3. You can download it from here.

PCA10028 is the name of the nRF51-DK board. This number is used for instance in the SDK release notes to tell what boards are supported, and in the SDK itself to contain the project files for the particular board. To use pca10028 you should use project files in the pca10028 folders, and hex files for labled with pca10028.
