I've previously used the RDM6300 with the Raspberry Pi 1 and it worked flawlessly. After switching to the Raspberry Pi 3 it won't read RFID tags anymore.
I'm certain I've connected everything correctly and the module is running. I've also edited config.txt (added
enable_uart = 1) and cmdline.txt (removed
The python script I use looks as follows:
#!/usr/bin/python # coding=utf-8 import serial # This is where I read the RFID tag def read_rfid(): ser = serial.Serial("/dev/ttyAMA0") ser.baudrate = 9600 daten = ser.read(14) ser.close() daten = daten.replace("\x02", "" ) daten = daten.replace("\x03", "" ) return daten id = read_rfid() print id
That's all I needed to get the script working on my old Pi 1. What changed from Pi 1 to Pi 3? What additional changes do I have to make?
