[IOERROR] - problem when doing i2c communication on the raspberry pi 5 using the Elechouse NFC Module V3

[ekinsol]

What happened?

I have a PN532 NFC MODULE V3 connected over i2c.

OS: Debian GNU/Linux 12 (bookworm)
Device: Rasbpberry Pi 5

sudo i2cdetect -y 1 -> Shows it connected on 0x24
nfc-poll also detects cards:

nfc-poll uses libnfc 1.8.0
NFC reader: PN532 over I2C opened
NFC device will poll during 36000 ms (20 pollings of 300 ms for 6 modulations)
ISO/IEC 14443A (106 kbps) target:
ATQA (SENS_RES): 00 44
UID (NFCID1): 04 a3 0b 5a eb 6c 80
SAK (SEL_RES): 00

Couldn't get my scripts to work, so now switched to the example (ntag21x_rw.py).

When running the sample, I get this error.

OSError: [Errno 121] Remote I/O error

I can confirm that there is data (0) returned on the SMBus.

import smbus

bus = smbus.SMBus(1)  # I2C bus 1
address = 0x24        # Replace with your NFC device's address
try:
    data = bus.read_byte(address)
    print(f"Read byte: {data}")
except Exception as e:
    print(f"Error accessing I2C device: {e}")

Reproducibility

Always (100% of runs)

Steps to Reproduce

1. Run example ntag21x_rw.py with i2c connection set to true

Code to reproduce

ntag21x_rw.py example

Host Controller

Raspberry 5

Python Version

3.8

Interface Mode

I2C

Power Supply

Wall adapter 5V

Logic Traces and other details

Can't get sigrok to work :/

Adding info:

After running ntag21x_rw.py and receiving the error, when I do nfc-poll, I get this error message:

nfc-poll uses libnfc 1.8.0
error libnfc.chip.pn53x Unexpected PN53x reply!
pn53x_check_communication: Input / Output Error

Running it the second time then works:

nfc-poll uses libnfc 1.8.0
