Context

The environment

Wireless assessment work benefits from portable tooling that can capture useful evidence without requiring a full workstation at every step.

Problem

What needed to change

Combine constrained hardware, wireless protocol handling, and evidence export into a practical workflow for authorized testing and analysis.

Constraints

  • Limited embedded memory and compute resources.
  • Different capture and inspection requirements across Wi-Fi and BLE.
  • Evidence needed to remain exportable to standard analysis tools.

Contribution

My responsibility

  • Embedded architecture and implementation
  • Wi-Fi and BLE capture workflows
  • Frame inspection and evidence handling
  • PCAP export and report generation

Approach

How I structured the work

Design around constrained hardware

Keep capture, inspection, and export responsibilities explicit so the device can perform useful work within embedded resource limits.

Preserve standard evidence

Export captures in PCAP-compatible form so deeper inspection can continue in established desktop analysis tools.

Connect events to a timeline

Generate reports and chronological evidence that make captured activity easier to review and communicate.

Outcome

What the work established

  • Combined Wi-Fi and BLE evidence collection in a portable embedded platform.
  • Supported PCAP export for established analysis workflows.
  • Connected raw capture activity to reporting and timeline evidence.
