Your beacon comes with FW 1.1, which has SoftDevice 7.1 preinstalled. If your application uses an older SoftDevice than this, you may need to flash the older SoftDevice as well.</p> <p>If it continues with the blinky example, an error occurred when uploading (or verifying) and the new application was not written to flash. Are you correctly creating the init-file? <a href="http://developer.nordicsemi.com/nRF51_SDK/nRF51_SDK_v8.x.x/doc/8.0.0/s110/html/a00092.html">developer.nordicsemi.com/.../a00092.html</a></p><div style="clear:both;"></div>
