I'm working with an R503 fingerprint sensor and a Raspberry Pi, and I'm encountering an issue where I'm receiving a "Failed to Read Data from Sensor" error message.I am using the libraries that adafruit gives you and I am trying to run the fingerprint_r503_rpi.py. I've checked my wiring and connections, ensured that the power supply is stable, and verified the serial communication settings. However, I'm still unable to establish communication with the sensor.
