With the Barcode Scan App it is possible to scan barcodes using a Bluetooth barcode scanner. This allows you to scan barcodes with your smartphone or tablet. A Bluetooth barcode scanner connects to your phone or tablet via the wireless Bluetooth connection.
The scanner connects as a Human Interface Device (HID). This means the scanned barcodes are passed to the phone as keyboard input. Make sure the barcode scanner is configured to send an enter (code 13) after scanning the barcode. This ensures the scanned barcode is recognised by the Barcode Scan App and processed immediately. Sending an enter after scanning is also known as a suffix.
Depending on your scanner type, you can enter the enter command as follows:
| Decimal | Hexadecimal | Octal | Code | Description |
| 13 | 15 | 0x0D | \r | CR (Carriage Return) |
