  • Use the Filter parameter as much as you can. It will be easier to establish a connection between devices.



Scanner Type 111:

  • The use of ScannerType: 111 for Zebra devices requires the BT Pairing service at Android Accessibility menu option to be activated. In addition, it is convenient to use UnpairAll: false, to avoid having to scan multiple times to connect the scanner. UnPairAll: true could be more problematic when you establish the connection between the device and the scanner.
  • Before using the scanner, please, scan the Non-Discoverable and the AutoReconnect barcodes:
