I assume that you are using SoftDevice s110 version 8.0.0, which is included with the SDK. I also assume that you are using the pca10028 DK. Correct me if I am wrong.</p> <p>When following the <a href="http://developer.nordicsemi.com/nRF5_SDK/nRF51_SDK_v8.x.x/doc/8.1.0/s110/html/a00073.html#project_hid_keyboard_test">HID Keyboard Testing procedure</a>, where does the board behave differently / at what steps are things going wrong and how?</p> <p>Regards, Terje</p><div style="clear:both;"></div>
