https://devzone.nordicsemi.com/f/nordic-q-a/68581/third-party-nfc-chip-is-woken-up-by-ble-advHello, We are using nRF52832 to develop a door lock controller. As nRF52832 cannot work as NFC master, we use another chip to read M1 cards. Everything goes well, except that the NFC chip is occasionally woken up if BLE adv is enabled. Not sure if thisen-USTelligent Community 13Mon, 23 Nov 2020 14:15:08 GMThttps://devzone.nordicsemi.com/thread/281348?ContentTypeID=1Mon, 23 Nov 2020 14:15:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:314abf2d-be38-4dbd-a95a-beb7096ca385ketiljo<p>It could be be something with the design of the NFC chip. You should reach out to the manufacturer of this chip and ask them.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/281160?ContentTypeID=1Fri, 20 Nov 2020 15:32:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:51aa932e-d1da-4be1-a107-dae159aad9a4Gary Gu<p>Sorry I did&nbsp;not make it every clear about the &quot;wake up&quot; feature. The NFC chip is normally in a Low Power Card Detect (LPCD) mode.&nbsp;It will trigger an interrupt to wake up <span>nRF52832 to do card reading,&nbsp;</span>when a card comes&nbsp;into the field. So this is a feature by design, we cannot turn it off. It is observed the interrupt is triggered occasionally without any card in field, when BLE adv is turned on.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/281064?ContentTypeID=1Fri, 20 Nov 2020 10:05:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7fdbcce5-a09e-4fd8-a172-b46ca9e60615ketiljo<p>Can you turn off the wake up on the NFC chip? If it&#39;s a reader only, there&#39;s no reason for it to wake up on field.&nbsp;</p><div style="clear:both;"></div>
