Hi Dimi,

As our discussion, it looks like NFC failed comes from nxp abnormal.
Could you please help to check this part? Thank you :)

Hi Viral,
I found that in libnfc-nci
NFCSTATUS_INVALID_DEVICE is defined as 6 in phNfcStatus.h
And gpphTmlNfc_Context->pDevHandle is opened in function |phTmlNfc_i2c_open_and_configure| and the handle value returned by open function is also 6 in this case.

So it will treat  gpphTmlNfc_Context->pDevHandle as an invalid device and then NFC cannot be enabled correctly. I have tried making open function return a "non 6" value then everything works fine.

I think the problem is that we should not treat "6" as invalid value because it is actually a valid handle value returned by open function, please check this with t2m, thanks!

I think this bug no longer exist since bug 1153155 already landed.
