https://devzone.nordicsemi.com/f/nordic-q-a/19723/nrf52-s132-antenna-steeringHello, recently I&#39;ve been going through SDK v12.2 and board documentation but I can&#39;t find any info about choosing which of board&#39;s antenna to use. Simply, I&#39;d like to know if I can send for example one packet of data by pin P0.09, then switch to pinen-USTelligent Community 13Wed, 15 Feb 2017 15:18:09 GMThttps://devzone.nordicsemi.com/thread/76745?ContentTypeID=1Wed, 15 Feb 2017 15:18:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a4076afe-735f-4102-b536-aa15e3564095J&#248;rn<p>Hi Oskar,</p> <p>As you mention GPIO P0.09 and P0.10 (Pin 11 and 12 on the chip) I assume you’re talking about the NFC antenna. The NFC antenna is a differential antenna which uses both pins simultaneously when sending, or receiving, a signal. So you do not choose between them when using the NFC.</p> <p>For NFC antenna interface see Figure 6: <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Fnfc.html&amp;cp=2_2_0_41_7&amp;anchor=concept_wpf_bzd_fq">infocenter.nordicsemi.com/index.jsp</a></p> <p>The other antenna on the board is a single end monopole antenna for 2.4GHz BLE, which is connected to pin 30 on the chip (Not shared with GPIO). For further information, I recommend reading the NFCT chapter of the nRF52832 product specification</p> <p>Best regards</p> <p>Jørn Frøysa</p><div style="clear:both;"></div>
