Program Keil generated hex file with nRFStudio

[Bryan]

I need to program the hex application image into the PCA10001 board. However, if I program the hex file generated by the Keil compiler using nRFStudio, the application does not run correctly. The S110 is programmed correctly.

If I program using the Keil tool, the application runs fine. What am I missing?

It ended up that the PCA1001 required a power reset (i.e. unplug USB cable) for it to advertise correctly.
