When I bring a valid RFID tag close to the sensor, I hear the normal beep. However, there is no sign of the tag id when getting a list of tags via example 5 from the library. What's weird is last time I used it, a few months ago, everything worked.
Code: Select all
RFID Tag: -1-1-1-1-1-1 Scan Time: 4294967.50
RFID Tag: -1-1-1-1-1-1 Scan Time: 4294967.50

Help would be appreciated :)
