Can't get PN532 and NEO air To work

Moderators: chensy, FATechsupport

Hi everyone,

I try to set up a PN532 (correctly set to HSU mode) module on a NanoPi Neo Air with UART.

I'm using a 3.3V output, ground, and UART1_TX/GPIOG6 connected to PN532 Rx and UART1_RX/GPIOG7 connected to PN532 Tx.

I'm trying to read serial with :

Code: Select all

cat /dev/ttyS1
(I've tried S0,S1,S2)

or with :

Code: Select all

./comtest -d /dev/ttyS1 -s 115200


But got no output.

How can I read data from this UART ?

Thanks a lot !

Did you enable UART1 ?
Did you enable UART1 ?


All 3 UART are enabled.
