GrovePi + Grove - 125KHz RFID Reader + Python

[jeroen_schuiten]

Hi,

I bought a Raspberry Pi in combination with the GrovePi+
Now I’m trying to make the Grove - 125KHz RFID Reader to work in Python.

I’m super new to programming. Many attempts to find a good tutorial/sample code online has lead to nothing.
If I’m correct, the module should be plugged into the RPISER port of the GrovePi+.

I also found this forum topic:

125 khz RFID Reader sample (Python or NodeJS)

Hi all, I recently purchased a new set of sensors, including the 125Khz RFID reader with some tags. I thought there would be some samples for this, but couldn't find any. Besides that, the reader uses Serial port communication and it's not that straightforward to use... I'm using my GrovePi+ with a Raspberry Pi 3. Does anyone have a running sample for this for Python or, even better, NodeJS? Thanks

but the provided example seems to be for Arduno. I’m using a Raspberry Pi

I’m using the following:

• Raspberry Pi 3
• GrovePi+
• Grove - 125KHz RFID Reader

Hi @jeroen_schuiten,

We don’t have example programs for the Grove RFID Reader at the moment.

Please give us a day or two to come up with a solution for you.
We will reach back to you.

Does this sound good to you?

Thank you!

Hi @jeroen_schuiten,

As I don’t have a Grove RFID Reader on my hands I can only give you a “rough” estimation of what you should have.
You will need to have the pyserial package installed in order to use the following python script.
In this script, when I message is received on the serial line, it’s gets printed in the console and then the program ends.

import serial
import time

rpiser = serial.Serial('/dev/ttyAMA0', baudrate=9600, timeout=0)
rpiser.flush()

while rpiser.inWaiting() == 0:
    time.sleep(0.005)

serial_data = rpiser.readline()
print(serial_data)

I think this script should work for your needs.

Thank you!
