Test QR-log Bridge under practical field conditions.
This page is the hands-on validation surface for QR-log Bridge. Use it to test reconstruction quality, robustness, handling on iPhone and iPad, and behavior under different distances, angles, lighting conditions, and device movement.
The sample viewer gives you multiple stream profiles, including a new superrobust sequence for harsher scan environments and stress testing.
Choose the profile that matches the test condition.
Each GIF variant stresses the receiver differently. Use smaller streams for quick validation, larger ones for throughput and sustained scanning, and the super robust stream for difficult real-world capture scenarios.
Fast setup and short validation loops
Useful when you want a quick end-to-end confidence check with minimal scan time.
Balanced validation stream
Best for routine testing of throughput, stability, and standard reconstruction behavior.
Higher resilience for difficult capture conditions
Useful when you want to push robustness harder under movement, distance, or less ideal optical conditions.
Switch streams, monitor load state, and preview the active GIF.
What to test and what to watch for.
What to test
Focus on scanning reliability, transfer completion, iPad and iPhone landscape layout behavior, optional header handling, and file reconstruction under real-world conditions such as different lighting, distances, angles, and device movement.
How to test
- Launch the app on an iPhone or iPad.
- Open this sample page or the fullscreen viewer.
- Scan the QR frames using the app camera.
- Switch between the GIF variants and compare behavior.
- Verify that the file is reconstructed correctly.
- Check preview, share action, stored file library, and debug export if enabled.
Key features under test
- QR code-based file transfer
- Optional protocol headers with default fallback settings
- Block-based parity and FEC recovery
- Interleaved replay and repeated parity frames
- CRC32 and SHA-256 verification
- Camera lens selection, tap-to-focus, and zoom
Special notes
- Camera access is required and used only for QR scanning.
- No external hardware is required.
- The app is designed as an offline transfer bridge.
- If no header is present, the receiver falls back to default protocol settings.
- The build includes a local received-files sheet for previous transfers.
