RFID2 unit not working with UIFlow 1.12.5 / Core2 Burn 1.9,8

[falbriard]

I have an RFID reader device model "RFID2", default port A(33,32) programmed by UIFlow 1.12.5. I also did a new burn ate the M5burner with image 1.9.8. The tutorial explains:
"RFID2 compared to the previous generation RFID UNIT only makes the replacement of read and write IC (RC522->WS1850S), there is no difference in function.The product has been discontinued."

The RFID "card near" and "card uid" functions are working OK, but no read, or write string at address 1, or other addresses. It gives a blank return information. Any hint how to fix it?
