Hi,
In our current project we using IMX8MM with NXP's own PN7150 NFC which runs Android 11. We have successfully integrated and have a working solution on the custom board, BUT we wanted to decrease to TListen time from 550 Ms which we are currently observing down to 250 or 300 ms.
from all the documents we found
Name NCI Tag Length Default value Description
Total_Duration 0x00 2 0xE803 Total duration of the single discovery period in [ms-Little endian coded] TLISTEN = Total_Duration - TPOLL
reference: AN11757.pdf
We tried to add the same to libnxp-nfc.conf
# Core configuration settings
NXP_CORE_CONF={ 20, 02, 2B, 0D,
00, 2C, 01
28, 01, 00,
21, 01, 00,
30, 01, 08,
31, 01, 03,
33, 04, 01, 02, 03, 04,
54, 01, 06,
50, 01, 02,
5B, 01, 00,
60, 01, 0E,
80, 01, 01,
81, 01, 01,
82, 01, 0E,
18, 01, 01
}
But we have not observed any change in TListen times on the oscilloscope.
Thank you
