Was there a new release / change with API for RFID-Reader of the MC9090-Z? The Motorola-DEMO works, but our Application can't read TAGS via API anymore.. Error-Description

READER CAN’T READ TAGS with MC9090- Symbol.RFID.Reader-API

(problem occurred only with THAT device, other devices working fine!)

this.MyReader = new Symbol.RFID.Reader();

(…)

this.MyReader.Parameters.TagType = Symbol.RFID.Tag.Types.EPC_CLASSG2;

(…)

this.MyReader.ReadNotify – Event:

Symbol.RFID.ReaderData TheReaderData =                    (Symbol.RFID.ReaderData)this.MyReader.GetNextReaderData();

TheReaderData.Result is Symbol.Results.SUCCESS !

 
but TheReaderData.TagList.TotalTags is always 0
