Class NWKGPHandler

14-0563-19 #A.3.8.2 (Commissioning mode control)

Put the coordinator in Green Power commissioning mode.

SPEC COMPLIANCE NOTES:

• ✅ Enables commissioning for bounded window (defaults to 180 s, clamped to 0xfe)
• ✅ Clears existing timer before starting new session to avoid overlap
• ✅ Logs entry for diagnostics; required commands are gated on this flag elsewhere
• ⚠️ Does not broadcast commissioning state to sinks; assumes host-only coordination

14-0563-19 #A.3.8.2 (Commissioning mode control)

SPEC COMPLIANCE NOTES:

• ✅ Cancels active commissioning timer and resets state flag
• ✅ Logs exit for diagnostics, matching spec recommendation for operator visibility
• ✅ Clears duplicate tables only when stop() invoked to preserve replay protection during window
• ⚠️ Additional cleanup (e.g., pending key distribution) not yet triggered here

14-0563-19 #A.3.5.2 (Duplicate filtering)

SPEC COMPLIANCE NOTES:

• ✅ Maintains per-source security frame counter as primary replay protection metric
• ✅ Falls back to MAC sequence number when security not in use, per spec guidance
• ✅ Applies timeout window to age entries out of duplicate tables
• ✅ Handles both source ID and IEEE/endpoint addressing forms
• ⚠️ Does not persist counters across restarts; relies on runtime tables only

14-0563-19 (Green Power) #A.3.8.2

SPEC COMPLIANCE NOTES:

• ✅ Parses NWK GP command identifier and forwards payload to Stack callbacks
• ✅ Enforces commissioning-mode requirement for commissioning/success/channel request commands
• ✅ Applies duplicate filtering prior to forwarding (isDuplicateFrame)
• ⚠️ Does not validate security parameters beyond duplicate table (future enhancement)
• ⚠️ TLV decoding delegated to consumer (payload forwarded raw)
