I am trying to discover why my Pi 3 is not able to communicate with PN532 NFC module.
I'm using a couple of libraries to do it (libnfc and NPM PN532), but it's not working.
I followed the steps of the folowing answer and other sites, but I still having problems.
The only difference that I have to the answers I've consulted are in my file /boot/cmdline.txt:
dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p7 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait
dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait
Does anyone had this error in your new Raspberry Pi 3? Thak's for your attention to my question.
Error in libnfc:
pn53x_check_communication: Success error libnfc.driver.pn532_uart Unable to transmit data. (TX) lt-nfc-poll: ERROR: Unable to open NFC device.
NPM PN532: Keeps idling in this message:
