Hello everyone !
I'm trying to use the UHF RFID Unit (JRD-4035) to collect the ID of an UHF tag.
It's linked to an ESP-Wroom-32 chip thanks to UART.
I use a simple code on micropython but I can't read any tag. It returns me nothing.

import machine
import time

print("Lancement du programme")

#uart = UART(1, 115200)                         
#uart.init(115200, bits=8, parity=None, stop=1)

uart = machine.UART(2, baudrate=115200, rx=16, tx=17)

print("UART connexion created")
print("Waiting for a tag")
while True:
    if uart.any():
        data = read_rfid()
        # check if a tag has been detected
        if len(data) > 0:
          print("Tag detected: {}".format(data))
        time.sleep(0.5)

I work with these tag, maybe they are not compatible with this unit : https://www.amazon.fr/dp/B07B6LSKXG?psc=1&ref=ppx_yo2ov_dt_b_product_details

Is there anybody who tried to do something like this ?
If you have example in Arduino, I'm interested to !

Thank you and have a nice day.
