Two different batches of pn7150 NFC modules have different effects

[xiaoliu5116]

Two different batches of pn71501 NFC modules have different effects。

i exchange pn71501 chips and find that the effect is only related to the chip!!

1、does the solution integrator burn some production batch based parameters into the chipsets?
2:libnfc-nxp.conf file,NXP_RF_CONF_BLK_1 and NXP_RF_CONF_BLK_2,Please tell me how to adjust these two parameters。

Hi 

For different batches, the pre-installed firmware version maybe different.  you can contact with the distributor for more details.

Hi 

For the RF configuration settings, I would suggest you refer to AN11755: PN7150 Antenna Design and matching guide.
