How to Enable Specific Barcode Formats with Your License

« Back to FAQ index

Problem

When moving from a trial license to a production license, you may encounter the error [xxx] No license found if your enabled barcode formats don’t match the formats supported by your license. This occurs because the SDK validates enabled formats against your license’s capabilities.

Solution

Explicitly enable only the barcode formats covered by your license in your code configuration.

Step-by-Step Guide

1. Check Your License Coverage
   Confirm which barcode formats your license supports (e.g., QR Code + 1D barcodes).

2. Configure Barcode Formats
   Update your code to explicitly enable only the licensed formats.

   • Example for Enabling QR Code Only:

      let settings = await router.getSimplifiedSettings("ReadSingleBarcode");
      // Enable QR Code only
      settings.barcodeSettings.barcodeFormatIds = 
        Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE;
      await router.updateSettings("ReadSingleBarcode", settings);
      await router.startCapturing("ReadSingleBarcode");
     

   • Example for Enabling Multiple Formats:

     Use bitwise OR (|) to combine formats.

      // Enable QR Code and 1D
      settings.barcodeSettings.barcodeFormatIds = 
        Dynamsoft.DBR.EnumBarcodeFormat.BF_QR_CODE | Dynamsoft.DBR.EnumBarcodeFormat.BF_ONED;
     

3. Verify Supported Formats
