Hi,

first of all thank you for you SimpleReader. It works fine :)
Do you have any idea to read faster? We have the RFID reader under remote-controlled cars and the Tags lie on the ground. The problem is, that the cars drive too fast over the tags, so that the reader can't read.

We have no idea to improve that. Maybe you have an idea? :)

Thank you :)

Hi, I am trying to use this reader to read an RFID device in someones hand. https://dangerousthings.com/shop/xm1-plus/

We are not having a lot of luck, it requires a lot of moving the hand around the reader to get it working.

I've read that it's possible to increase the gain of the reader. I tried looking for a method in your code, but couldn't see anything that would let me increase the gain of the reader.

Can you help?

I see that 1 CPU core is at 100% usage when I run 01_read.py script.
There is this while 1 loop, but it blocks somewhere inside.

Is there a work around - What could be done to fix this ?

Hi,

I'm experiencing an issue where the python script hangs and the rfid reader crashes. The script is based off the SimpleMFRC522 library. Have you experience this before?

My current code is this:

`reader = SimpleMFRC522()

try:
# Welcome message
print("Welcome to the MFRC522 data read example")
print("Press Ctrl-C to stop.")
id = None

while True:
    dbConnection = pymysql.connect(
        host=config.host, user=config.user, passwd=config.passd, db=config.dbname, charset='utf8mb4', cursorclass=pymysql.cursors.DictCursor)
    cur = dbConnection.cursor()
    # Get the UID of the card
    id = reader.read_id()
    print(id)
    cur.execute("SELECT * FROM access_list_2 WHERE rfid_code = %s;", (id,))
    if cur.rowcount != 1:
        print ("Access Denied")
        # Log access attempt
        cur.execute("INSERT INTO access_log SET rfid_presented = %s, rfid_presented_datetime = NOW(), rfid_granted = 0", (id,))
        dbConnection.commit()
        id = None
        dbConnection.close()
    else:
        GPIO.output(12, GPIO.HIGH)
        # Log access attempt
        cur.execute("INSERT INTO access_log SET rfid_presented = %s, rfid_presented_datetime = NOW(), rfid_granted = 1", (id,))
        dbConnection.commit()
        time.sleep(5)
        GPIO.output(12, GPIO.LOW)
        id = None
        dbConnection.close()
   time.sleep(1)

except:
logging.exception("message")
finally:
GPIO.cleanup()
raise
