 I would like to use an external GPS active antenna on the nRF9151 EVB for testing (J2), does it disconnect the on board antenna GPS ? should I connect/disconnect any solder bridge ? 
 How does it works ? priority ? 
 
 Tnx,

This is done by ensuring that the&amp;nbsp;&lt;/span&gt;&lt;span&gt;VEN&lt;/span&gt;&lt;span&gt;&amp;nbsp;signal is low and set using&amp;nbsp;AT&lt;/span&gt;&lt;span&gt;%XCOEX0.&amp;nbsp;&lt;/span&gt;You can find relevant information in the documentation -&amp;nbsp;&lt;a href="https://docs.nordicsemi.com/bundle/ug_nrf9151_dk_jp/page/UG/nrf91_DK/hw_description/antenna_interfaces.html"&gt;antenna interfaces&lt;/a&gt;&amp;nbsp;and&amp;nbsp;&lt;a href="https://docs.nordicsemi.com/bundle/ug_nrf9151_dk_jp/page/UG/nrf91_DK/hw_description/gnss.html#gnss"&gt;GNSS&lt;/a&gt;.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Best regards,&lt;br /&gt;Dejan&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
