Hi,
I'm using nRf52840 rev B and C chipset and not able to detect the NFC on the device (the rev A chipset is working). Following SW combination is used:
nRF5_SDK_15.0.0_a53641a
t2t_lib
s140_nrf52_6.0.0_softdevice
I've tested this both with our application and the sample example in examples/nfc/record_url. NFC can not be detected if Rev B or C of the chipset is used.
Thanks,
Ramtin
