So I strongly suggest that you fix these issues.&nbsp;</p> <p>Issue 3: SHould not affect the programming of the chip, but the incorrect load caps will most likely lead to the RADIO peripheral not working properly. So if you are using the RADIo for BLE, then you need to apply the correct load caps corresponding to the CL value of the crystals you have selected.&nbsp;</p> <p>Best regards</p> <p>Bj&oslash;rn</p><div style="clear:both;"></div>
