There should be a green pulsing light when connected and waiting to be detected by the Power Profiler application.</p> <p>You can try turning the device off, removing any power sources from it, then remove the plastic cover by unscrewing the four screws in the corner. Then short a connection between GND and TP34 on the PPK2 with a jumper. Put the cable back in USB DATA/POWER and power the board back on, remove the jumper after powering the kit on. This should put it into bootloader mode, and let you see the device as a serial number in the Power Profiler app. When selecting it it should get a prompt where you can program the Power Profiler application onto it, and let it move to normal operation.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
