Hello, I purchased 2 sets of Ultra-Small UHF RFID Tag Rain & the SparkFun Simultaneous RFID Reader - M6E Nano cant read them. Also the UHF RFID Ring Antenna is retired, so how am I supposed to use the ultra small tags ?

What happens if you put the small tags nearly on-top-off the M6E-Nano antenna ?

Nothing happens. I’m guessing I should return them.

weird indeed. Does the M6E connect correctly with the sketch and is trying to read the EPC ?

Yes, I can read other tags. I just cant read the rain tags.
