Can we write simple code to test the board without SoftDevice support?

[ligang]

All of Nordic 's example need the SoftDevice support?

I want to know , can we use simple code to test the board without SoftDevice?

[Susheel Nuguru]

try the example nRF5_SDK_12.1.0_0d23e2a\examples\peripheral\blinky\pca10040\blank

All examples inside SDK\examples\peripheral\xxxx\board\blank do not use softdevice.

But, when I use nRFgoStudio erase all, and download the code by keil . the led can not lighting.

when I use the nRFgoStudio download the SoftDevice first and then download the code by keil

The led can lighting . So, I ask the program.

then you are compiling the application with wrong project. You have to use blank project as mentioned my answer nRF5_SDK_12.1.0_0d23e2a\examples\peripheral\blinky\pca10040\blank
