How can I program the nRF51422 (specifically the pca10028 dev kit) using Makefiles? I have the latest SDK, but all of the examples are for nRF52 boards. I looked in an older SDK (11.0.0) and found and example for the pca10028, but when I tried to run make, it wouldn't work; it failed to create the _build directory and, if I added it, failed to proceed to the next stage.
Can someone walk me through how to get a basic bluetooth example working? It has to be using Makefiles due to the nature of the project I'm using the board for. I've trawled through documentation but so far nothing has been helpful.
I am running Windows 10, I have gcc, nrfjprog etc.already installed. The examples for the nRF52 in SDK 15.2.0 worked fine.
