Hi there,

I'm building your project. Can you let me know where I should put the above modifications? Thanks.

Hi,

Can you try to move the nrfx_spis_buffers_set() to the main loop and use a flag to wait for the buffer to be set successfully? Here is an example that implements exactly this, it was written for an earlier version of NCS so it's a bit outdated but it can be used as a reference on how to implement a master and slave.

Hi there,

I'm not able to build your project, it seems that it's dependent on a common.cmake file. Is this file already in the nRF Connect SDK, where should I place your sample folder for it to build successfully?
