✅ COMPLETED DELIVERABLES

Core Driver Enhancements

• ✅ LBT Implementation: wpanusb_set_lbt() implemented in wpanusb.c:906-932
• ✅ Frame Retry Mechanism: wpanusb_set_frame_retries() implemented in wpanusb.c:934-959 with proper validation
• ❌ Dynamic Configuration System: Hard-coded arrays still present (wpanusb_powers[] in wpanusb.c:490)

Firmware API Extensions

• ❌ Device Information APIs: Command enums exist but handlers not implemented
• ❌ Advanced Features: Management frames, scanning capabilities not implemented

Testing & Validation

• ✅ Basic Test Suite: Test directory exists with networking test scripts
• ❌ Automated CI/CD: No evidence of CI integration
• ❌ Hardware Testing: No comprehensive test results documented

Documentation

• ✅ Technical Documentation: README files present for both drivers
• ✅ Planning Documents: Comprehensive implementation plans exist
• ❌ API Documentation: Missing detailed API docs for new functions

Code Quality

• ✅ Driver Implementation: Core functions implemented with proper error handling
• ❌ Stub Removal: Still contains -ENOTSUPP stubs in firmware
• ❌ Upstream Standards: No evidence of checkpatch.pl validation

❌ MAJOR GAPS REMAINING

Critical Missing Items:

1. Firmware Handlers: SET_LBT and SET_FRAME_RETRIES commands have cases but no implementations
2. Dynamic Configuration: Hard-coded wpanusb_powers[] and channel arrays still present
3. Device Capability APIs: All get_* functions missing from firmware
4. bcfserial Driver: No evidence of LBT/retry implementation
5. Upstream Patches: No patch series prepared for linux-wpan
6. Video Documentation: No YouTube videos found

Implementation Status:

• Driver Side: ~60% complete (core functions implemented, missing dynamic config)
• Firmware Side: ~20% complete (command structure exists, handlers missing)
• Testing: ~30% complete (basic tests only)
• Documentation: ~70% complete (planning docs good, missing API docs)
• Upstream Ready: ~10% complete (major refactoring needed)

🚨 URGENT PRIORITIES

1. Implement firmware handlers for SET_LBT and SET_FRAME_RETRIES
2. Remove hard-coded arrays and implement dynamic capability queries
3. Complete bcfserial driver equivalents
4. Prepare upstream patches following kernel standards
5. Create required video documentation

Your project has solid foundational work but needs significant completion for successful GSoC submission.

wpanusb_bc Firmware Integration Test Scenarios

Overview

This document outlines comprehensive integration test scenarios to validate the wpanusb_bc firmware implementation with real hardware and the Linux wpanusb driver.

Hardware Setup Requirements

• BeagleConnect Freedom board with CC1352P7
• BeaglePlay or Linux host system
• USB cable for wpanusb connection
• Optional: UART connection for bcfserial testing … +335 lines (ctrl+r to expand)
