https://devzone.nordicsemi.com/f/nordic-q-a/97523/nina-b301-connectivity-without-an-antennaHello all, We are experiencing odd behavior with a custom board which is using the NINA B301 by UBlox. This module contains the NRF52840 SoC inside. Looking through the product page here , it appears that there is nothing being done with this moduleen-USTelligent Community 13Thu, 09 Mar 2023 19:27:52 GMThttps://devzone.nordicsemi.com/thread/414488?ContentTypeID=1Thu, 09 Mar 2023 19:27:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a0c551e1-e2d7-4869-826e-1de90dee88f2jspear<p>That is interesting, I didn&#39;t know that it could have been powerful enough just by it being a no connect! Thank you for your response!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/414466?ContentTypeID=1Thu, 09 Mar 2023 16:49:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:644fab40-1f0e-419b-b854-d61c6ab06a03Turbo J<p>The unconnected antenna pin still emits <em>some</em> amount of RF radiation, and a close by receiver will be sensitive <em>enough</em> to detect and decode it.</p> <p>The only way to prevent that would be properly grounding the RF pin with a resistor (termination).</p> <p>You will se a severe reduction in connection quality and range, but you <em>can</em> operate BT and WLAN devices w/o a proper antenna in specific cases.</p><div style="clear:both;"></div>
