Error when receiving data from PN532

I am programming the PN532 board with the MSP430FR2433 microcontroller and when I send commands to the PN532 I do not get a valid response.

For example when I type the command to get the pn532 version (0x00 0x00 0xFF 0x01 0xFE 0xD4 0x02 0x2A 0x00) what I get is 0x80 the number of times I have told it the size of the message back.

On the other hand, if I write (0x00 0x00 0x00 0xFF 0x02 0xFE 0xD4 0x02 0x2A 0x00), I get 0x01 and it stops, does not enter the interrupt to read the next bytes it receives and stops forever.

I think the correct command is the second one, but it does not raise the flag to enter the interrupt to read the next bytes, it only reads the first one (0x01).

Can anyone help me, please?
