Summary by CodeRabbit

• New Features
  • Aggregate Format descriptors are now populated with the handles of registered Presentation Format descriptors when GATT services start. This makes the presentation-format information available through the aggregate descriptor. Unregistered services, characteristics, and descriptors are skipped.

Walkthrough

Arrr, after GATT services start, NimBLEServer::start fills each registered Aggregate Format descriptor with the handle bytes of registered Presentation Format descriptors. It clears the Aggregate Format value first and skips unregistered services, characteristics, and descriptors.

Aggregate descriptor initialization has bounded correctness gaps when replacing hidden descriptors or preserving manually supplied values. These warrant correction or explicit owner acceptance; broad startup failure is not established.

Full details: Title check

Explanation

Arr, the title "Add Aggregate Format Descriptor(0x2905) support" matches the changeset. The PR adds code in src/NimBLEServer.cpp that fills each characteristic's Aggregate Format descriptor (0x2905) with the handles of its registered Presentation Format descriptors (0x2904) after GATT services start. The title names the main change, so it passes.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 1 files.

_{The services start; the handles gleam,
0x2905 gathers 0x2904’s stream.
Clear the value, then bytes set sail,
Skip unregistered ports along the trail.
Arrr, the descriptors chart their course,
And GATT records each handle’s source.}

337-337: Minor · Potential issue · Low value

⚠️ Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The loop does not detect a failed NimBLEAttValue::append; the supplied append implementation silently leaves the value unchanged when its maximum length is exceeded. A 0x2905 value may therefore contain only the first few handles while start() reports success.

Peers receive an incomplete aggregate-format handle list with no startup failure.

This can occur when: The number of registered 0x2904 descriptors requires more bytes than the newly default-constructed NimBLEAttValue permits.

Review comments at @src/NimBLEServer.cpp:
- Line 327: Update the Aggregate Format population pass in
`NimBLEServer::start()` to skip removed descriptors when selecting the 0x2905
descriptor. Choose the first descriptor matching that UUID whose `getRemoved()`
state is false, so hidden descriptors cannot receive the value instead of the
registered replacement.
- Around line 333-334: Update NimBLEServer::start() to avoid unconditionally
resetting dsc2905->m_value before rebuilding the descriptor, preserving any
value supplied through NimBLELocalValueAttribute::setValue().
