How to connect multiple ST25R3916 readers to the java sdk

I'm needing to get readings from more than one st25r3916 at once for a project using the pc (and java sdk). I'm unsure as to how to do this because

"STReader stReader = new STReader(); stReader.connect();"

Always connects to the same reader - the only sucess i've had so far is by running 2 instances of the program which isn't fit for purpose.

Can anybody help?

    Hello Thomas,

    the ST25 Java SDK can manage several tags but only one reader at a given time, as you discovered.

    Unless you disable the COM port of the first reader before connecting to another reader, you will always find the same device first.

    Regards,
