https://devzone.nordicsemi.com/f/nordic-q-a/12945/compiling-ansc-application-for-pca10001Hi, I am trying to compile &amp; run ANSC example under SDK8 in a PCA10001 board. I have programmed the SoftDevice using nRF Go Studio. Here is the example, nRF51_SDK_8.0.0_5fc2c3a\examples\ble_peripheral\experimental_ble_app_ancs\pca10028\s110\arm5_no_packsen-USTelligent Community 13Mon, 04 Apr 2016 14:16:29 GMThttps://devzone.nordicsemi.com/thread/49313?ContentTypeID=1Mon, 04 Apr 2016 14:16:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a283f879-a45b-4d58-8585-e3e8c076e769Stefan Birnir Sverrisson<p>Hi Kumar</p> <p>This is normal behavior. The sd_app_evt_wait() function, puts the nRF51 CPU to sleep, and will therefore halt the debug. You would then need to restart the debug session and set a breakpoint after call to sd_app_evt_wait(). Also, debugging halts when sd_* softdevice function is called from your application, see <a href="https://devzone.nordicsemi.com/question/81/how-can-i-debug-a-softdevice-application/">this thread</a>. <a href="https://devzone.nordicsemi.com/blogs/821/an-introduction-to-error-handling-in-nrf5-projects/">This blog</a> also contains useful debugging info</p><div style="clear:both;"></div>
