Biscuit Manager vs Smith Designer Lite

This is the official companion application for the Biscuit hardware ecosystem. The Biscuit is a headless wireless auditing tool designed for wardrivers, security professionals, and even beginners. This application connects to the device via Bluetooth Low Energy (BLE) to provide a user interface for the device. Use this app to control scanning, analysis, and testing operations across 2.4GHz, 5GHz, and WiFi 6 networks. WiFi Capabilities Dual-Band Scanning: View Access Points, Stations, and Probe Requests across 2.4GHz and 5GHz bands simultaneously. a Traffic Analysis: Monitor channel utilization and capture beacon frames with security type detection. Handshake Capture: Capture PMKID and 4-way handshakes for analysis. Network Testing: Perform deauthentication testing (broadcast and targeted) and deploy captive portals. Threat Detection: Identify Rogue APs and known audit devices like Pwnagotchi or WiFi Pineapple. Bluetooth Capabilities Device Discovery: Scan for BLE and Classic Bluetooth devices, including tracker tags. Skimmer Detection: Identify potential credit card skimmers (HC-05/HC-06 modules). Wardriving: Log Bluetooth data with GPS integration and support for WiGLE uploads. Device Management Dashboard: View real-time connection status and battery levels. Configuration: Configure the RGB status LED for stealth operation. Firmware Updates: Perform Over-the-Air (OTA) firmware updates over WiFi. Hardware Required This application requires the Biscuit Pro physical device. It is not compatible with standard ESP32 hardware for 5GHz operations. Legal Disclaimer The Biscuit Pro and this application are designed for authorized security auditing, educational purposes, and research only. Users are responsible for ensuring they have proper authorization before testing any network or device. Misuse may violate local or federal laws.

Smith Designer is a powerful and interactive Smith Chart tool for RF and Microwave professionals, students, and hobbyists. Design, analyze, and optimize impedance matching networks directly on your mobile device. This is a feature limited version, a full featured version is also available. The Smith Designer Lite version allows up to 3 elements per network and up to 2 networks per project. Whether you are designing an antenna match, an amplifier interstage, or a filter, Smith Designer provides an intuitive interface to visualize impedance transformations in real-time. Key Features: • Interactive Smith Chart: Visualize impedance trajectories as you add components. Toggle between Impedance (Z) and Admittance (Y) grids. • Schematic Editor: Build matching networks using a drag-and-drop interface. Supports Series/Shunt Inductors, Capacitors, Resistors, series and parallel RLC, Transmission Lines (Series and shunt, Open/Short Stubs), Transformers, fixed jX and jB, and S2P blocks. • Real-Time Tuning: Adjust component values using sliders or by dragging points directly on the Smith Chart to see immediate effects. • Auto Match: Automatically synthesize L-network matching circuits to match a source to a load. • Simultaneous Conjugate Matching for unconditionally stable devices, and provisions to help stabilize conditionally stable networks. • Optimization: Built-in gradient descent optimizer to fine-tune component values for the best match. • Frequency Sweeps: Analyze your design over bandwidth. Plot S-Parameters (S11, S21, S12, S22), Gain (Ga, Gp, Gt), Noise Figure, Return Loss, and Group Delay. • Monte Carlo Analysis: Simulate manufacturing tolerances. Define component variations (Uniform, Gaussian, Triangular) and visualize the spread on the Smith Chart to ensure design robustness. • S2P/Touchstone Support including noise data: Import .s2p files for S-parameter blocks and .s1p files for frequency-dependent source/load impedances. • Vendor Libraries: Easily import and use component libraries (supports Murata LPB format, see https://www.murata.com/tool/data/librarydata). • Comprehensive Overlays: Visualize VSWR circles, Constant Q arcs, Stability circles, and Noise circles (requires noise parameters). • Load Pull Contours: Import multi-frequency Load Pull and MDIF files. Frequency interpolation (nearest, linear, cubic spline). Filled contours with 5 color maps. Reference/contour plane transforms through the matching network. • Data Explorer to assess SnP data files, load-pull data files, antenna patterns and more. Advanced Tools: • Analytical Line Models: Closed-form Z₀, loss, and synthesis for Coaxial, Parallel Lines, Twisted Pair, Microstrip, Stripline, Grounded CPW, Rectangular Waveguide, and Circular Waveguide. • Transmission Line Models: Constant Phase, Electrical Length, and Physical models with loss and velocity factor. • Resonator & Attenuator Designers: Built-in calculators for common circuit blocks. Export & Share: • Export professional PDF reports with schematics, charts, and plots. • Export designs as SPICE netlists for further simulation. • Save high-resolution PNG/SVG images. • Share project files to collaborate with others. Perfect for RF engineering coursework, ham radio antenna tuning, and professional circuit design. Unlock the power of the Smith Chart in your pocket!
