My laptop is the first one I have with a NFC reader, so I'm not used to test this as it was not working yet. I booted the machine with a 5.1.1, the series applied on top, and the config options set as mentioned above. The nxp-nci kernel module is loaded and neard is installed. I used the sniffing tool with the command libnfc -d nfc0 -n but when passing my NFC devices on the laptop's NFC mark, nothing happens.
