Using a Zebra MC3300 Device with Datawedge 8.0 +
I've been working on a scanning app that requires me to scan an RFID in step one and immediately scan a barcode in step two. The process is repeated to link the RFID and barcode in the DB. I've developed the app using the data wedge API but the scan is failed after a couple of scans the RFID scan doesn't scan anymore even though it is enabled and whether enable/disable the profile, restarting the app doesn't help either. When this happens I have to restart the device completely to get it to work again.
From the logs, I observed some sort of crashes and messages that I think might be helpful in understanding the issue. Any help is appreciated.
Thanks in advance.
