Duplicated request

Postby selectiveignorance » Tue Jul 18, 2017 1:10 am

I am trying to poll 4 RFID 1024 readers one by one. I am creating object for every reader and attaching the event handlers. However, inspite of closing the reader object I get a duplicated request exception.

Also, the TagLost event is not getting fired. Please help.

Are you specifying different serial for all 4 readers?

The duplicate exception happens either when you call open on and already opened phidget handle, or if you try to open the same phidget using 2 different handles - by specifying the same serial twice for example.
