https://devzone.nordicsemi.com/f/nordic-q-a/9649/ble-multilink-central-example-not-working-on-pca10028Hi, I am trying BLE multilink central example from SDK9 on PCA10028 board, but everytime device gets stuck at LEDS_CONFIGURE() in main.c. Below is my setup: Flash S120 softdevice via NRF Studio goto nRF51_SDK_9.0.0_2e23562\examples\ble_centralen-USTelligent Community 13Mon, 12 Oct 2015 12:18:54 GMThttps://devzone.nordicsemi.com/thread/35655?ContentTypeID=1Mon, 12 Oct 2015 12:18:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:44c2eb51-7881-4ee9-9659-1c67b5cf6e93Susheel Nuguru<p>not sure what you mean by debug stuck in LEDS_CONFIGURE!!! LEDS_CONFIGURE is the first debuggable line in main.c so i guess the blue arrow is just stalled because the device went to sleep mode. If you put a breakpoint at other lines, you will see that they are executed normally.</p> <p><img src="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/6013.Capture.PNG" alt="image description" /> When you run this application and hit stop, this blue pointer does not mean that the execution is still stuck there. It is not able to point to the correct place because the last execution was sd_app_event_wait() and then the chip went to sleep after executing the softdevice instructions.</p> <p>If you see the PC value, it points to inside the softdevice. Which is correct. <img src="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/3480.Capture.PNG" alt="image description" /></p><div style="clear:both;"></div>
