https://devzone.nordicsemi.com/f/nordic-q-a/35446/nrf52832-the-problem-about-the-use-of-32mhz-crystal-in-bluetoothHello, we are using the nRF52832 for building our custom board.After loading the example bluetooth_uart code given in the SDK, our board is not producing correct RF(Bluetooth advertisement) which is different from what is generated in the developmenten-USTelligent Community 13Fri, 15 Jun 2018 13:24:11 GMThttps://devzone.nordicsemi.com/thread/136381?ContentTypeID=1Fri, 15 Jun 2018 13:24:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bd84aa47-0477-493a-ab6e-1abdf4369d75FormerMember<p>What is the load capacitance of the crystal? And what is the values of the load capacitors in the layout? The value of the load capacitors should be calculated according to the formula in the &quot;Crystal and load capacitors&quot; section in <a href="https://devzone.nordicsemi.com/tutorials/b/hardware-and-layout/posts/general-pcb-design-guidelines-for-nrf52">this </a>tutorial.</p> <p>&nbsp;</p> <p>Does you application start, so that you can print over UART? If not, I would recommend you to check the LFCLK source as well. All examples in the SDK use an external 32 kHz crystal, if your board doesn&#39;t have an external crystal, the internal RC oscillator should be used instead.</p><div style="clear:both;"></div>
