https://devzone.nordicsemi.com/f/nordic-q-a/100912/frequency-offset-calibrationHi all: How to calibrate Bluetooth frequency deviation, can it be calibrated through the function interface? Thanks!en-USTelligent Community 13Tue, 24 Dec 2024 01:54:16 GMThttps://devzone.nordicsemi.com/thread/516196?ContentTypeID=1Tue, 24 Dec 2024 01:54:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b102a483-67d2-403e-91b2-e070e84161bfLongQi<p>is this the correct one?&nbsp;<a id="" href="https://docs.nordicsemi.com/bundle/nwp_006/resource/nwp_006.pdf">https://docs.nordicsemi.com/bundle/nwp_006/resource/nwp_006.pdf</a></p> <p>but it did not mention how to tune the load capacitors in the code.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/516081?ContentTypeID=1Mon, 23 Dec 2024 08:40:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:49866aed-1b3b-4bb6-b484-d824f390b683LongQi<p>could you help to update the document link?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/431462?ContentTypeID=1Fri, 16 Jun 2023 11:03:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:32b7da1d-779f-481e-b20c-b2c28560fe03Kaja<p>Hi,&nbsp;<br /><br />for the nRF52 series you adjust the frequency accuracy by adjusting the load capacitors on the 32 MHz crystal (HFXO).<br /><br />See chapter 4:&nbsp;<a href="https://infocenter.nordicsemi.com/pdf/nwp_006.pdf?cp=18_20">RF Performance Test Guidelines</a></p> <p></p> <p>If the carrier is higher then what you set is as: The load capacitors should have a higher value, and lower if the frequency is lower.&nbsp;<br /><br />Best regards,<br />Kaja&nbsp;</p><div style="clear:both;"></div>
