 I am developing a ble applications and am unable to get pins 9 or 10 to work as gpio. I understand that this is because, by default they are used by the NFC. 
 I have tried the following solutions: 
 1) defining the CONFIG_NFCT_PINS_AS_GPIOS</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 02 Aug 2017 19:34:56 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/24025/enable-pins-9-and-10-as-gpio-on-nrf52" /><item><title>RE: Enable pins 9 and 10 as GPIO on NRF52</title><link>https://devzone.nordicsemi.com/thread/94565?ContentTypeID=1</link><pubDate>Wed, 02 Aug 2017 19:34:56 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:bc42ab34-7ec7-47d7-94fb-b893ba741735</guid><dc:creator>endnode</dc:creator><description>&lt;p&gt;Hi Jeremy,&lt;/p&gt;
&lt;p&gt;SW part will help you to switch GPIO vs. NFC setting in nRF52 registers but on nRF52 DK there are HW elements to tune 13.56MHz antenna interface so you need to modify solder-bridges to make it really available for external GPIO. &lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/development/nrf52_dev_kit/hw_nfc.html?cp=2_1_4_5_10"&gt;See nRF52 DK guide&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;Btw. this was answered like 10 times in past 18 months... (see e.g. &lt;a href="https://devzone.nordicsemi.com/question/122106/cannot-get-p009-to-operate-as-a-gpio/"&gt;here&lt;/a&gt;).&lt;/p&gt;
&lt;p&gt;Cheers Jan&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
