🔍 BLELogger vs. others
The ZeroTrace BLELogger is not just a BLE HID device. It is a hybrid hardware and software analysis platform designed for live input monitoring, detection, and emulation. This page breaks down how BLELogger compares to traditional HID tools and why it is fundamentally unique.
🧩 What Makes BLELogger Different?
BLELogger is the only device in its class that combines BLE interception, keyword and regex detection, and a full keyboard calibration system. This enables accurate logging across any keyboard layout, language, or region.

🌍 Universal Keyboard and Language Support
🔧 Calibration System
BLELogger introduces a keyboard calibration system that removes the biggest limitation of keylogging.
Different layouts, languages, and scan codes.
What calibration enables
- Use any keyboard ANSI, ISO, custom
- Support all languages QWERTY, QWERTZ, AZERTY
- Correct mapping for special characters
- Accurate reconstruction of real text, not raw codes
| Feature | Other Devices | 🕵️ BLELogger |
|---|---|---|
| Layout-dependent | ❌ Yes | ✅ No |
| Language-agnostic | ❌ No | ✅ Yes |
| Custom Keymaps | ❌ No | ✅ Yes |
| Dynamic Re-mapping | ❌ No | ✅ Yes |
🌐 Software and Control Layer
BLELogger is paired with a modern web-based control interface.
| Feature | Classic Devices | 🕵️ BLELogger |
|---|---|---|
| Web Dashboard | ❌ No | ✅ Yes |
| Live Input View | ❌ No | ✅ Yes |
| Regex and Keyword Editor | ❌ No | ✅ Yes |
🧪 Detection Example
Example:
keywords:
- password
- login
- admin
- secretTriggers when any defined word is typed instantly.
Example:
regex:
- ([A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,})
- (password\s*[:=]\s*\S+)Detects emails, credentials, and structured input patterns.
🎯 Intended Use Cases
- Security research and testing
- Input behavior analysis
- BLE HID emulation and bridging
- Multi-language keyboard environments
- Advanced automation and detection workflows
ZeroTrace BLELogger is intended for authorized environments only. Always comply with local laws and obtain explicit permission.
🏁 Summary
ZeroTrace BLELogger is not a simple keylogger.
It is a hardware-backed input intelligence platform combining:
- BLE HID emulation
- Inline keyboard interception
- Keyword and regex detection
- Universal keyboard calibration
- Modern web-based control
No other device currently offers this combination in a single, compact unit.
