The official companion apps communicate with devices over BLE, but they are mobile-only. If you want to manage your MeshCore device from a desktop or laptop, the usual approach is to **flash USB-serial firmware** via the web flasher. However, this replaces the BLE Companion firmware, which means you can no longer use the device with mobile companion apps (Android/iOS). @@ -139,7 +141,7 @@ On macOS the address will be a UUID (e.g., `12345678-ABCD-...`) rather than a MA ### 3.

Monolith → package + +The single file was split into a `meshcore_gui/` package. Each class got its own module. Constants and `debug_print` moved to `config.py`. The original `meshcore_gui.py` became a thin entry point (101 lines) that wires components and starts the server. + +### 2. Protocol-based dependency inversion + +Four `typing.Protocol` interfaces were introduced in `protocols.py`: + +| Protocol | Consumer | Methods | +|----------|----------|---------| +| SharedDataWriter | BLEWorker | 10 | +| SharedDataReader | DashboardPage | 4 | +| ContactLookup | RouteBuilder | 1 | +| SharedDataReadAndLookup | RoutePage | 5 | + +No consumer imports `shared_data.py` directly. Only the entry point knows the concrete class. + +### 3. MeshCoreGUI decomposed into DashboardPage + 6 widgets + +The 740-line MeshCoreGUI class was split: + +| Old (MeshCoreGUI) | New | Lines | +|--------------------|-----|-------| +| 8 `_render_*` methods | 6 widget classes in `widgets/` | 592 total | +| 7 `_update_*` methods | Widget `update()` methods | *(inside widgets)* | +| 5 user-action methods | Widget `on_command` callbacks | *(inside widgets)* | +| `render()` + `_update_ui()` | DashboardPage (orchestrator) | 148 | + +DashboardPage now has 4 methods. It composes widgets and drives the timer. Widgets have zero knowledge of SharedData — they receive plain `Dict` snapshots and callbacks. + +### 4. Route visualisation (new feature) + +Two new modules that did not exist in the monolith: + +| Module | Lines | Purpose | +|--------|-------|---------| +| `route_builder.py` | 174 | Constructs route data from message metadata (pure logic) | +| `route_page.py` | 258 | Renders route on a Leaflet map in a separate browser tab | + +Clicking a message in the message list opens `/route/{msg_index}` showing sender → repeater hops → receiver on a map. + +### 5. SharedData extended + +SharedData gained 4 new methods to support the protocol interfaces and route feature: + +| New method | Purpose | +|------------|---------| +| `set_connected()` | Explicit setter (was direct attribute access) | +| `put_command()` | Queue command from GUI (was `cmd_queue.put()` directly) | +| `get_next_command()` | Dequeue command for BLE worker (was `cmd_queue.get_nowait()` directly) | +| `get_contact_by_prefix()` | Contact lookup for route building | +| `get_contact_name_by_prefix()` | Contact name lookup for DM display | + +The direct `self.shared.lock` and `self.shared.cmd_queue` access from BLEWorker and MeshCoreGUI was replaced with proper method calls through protocol interfaces. + +### 6.

Widgets depend only on `config` (for constants) and NiceGUI — they have zero knowledge of SharedData or protocols. + +--- + +## 2. SOLID assessment per principle + +### S — Single Responsibility Principle + +> "A class should have only one reason to change." + +| Module | Class | Responsibility | Verdict | +|--------|-------|---------------|---------| +| `config.py` | *(no class)* | Constants and debug helper | ✅ Single purpose | +| `protocols.py` | *(Protocol classes)* | Interface contracts | ✅ Single purpose | +| `shared_data.py` | SharedData | Thread-safe data store | ✅ See note | +| `ble_worker.py` | BLEWorker | BLE communication thread | ✅ Single purpose | +| `main_page.py` | DashboardPage | Dashboard layout orchestrator | ✅ See note | +| `route_builder.py` | RouteBuilder | Route data construction (pure logic) | ✅ Single purpose | +| `route_page.py` | RoutePage | Route page rendering | ✅ Single purpose | +| `widgets/device_panel.py` | DevicePanel | Header, device info, actions | ✅ Single purpose | +| `widgets/map_panel.py` | MapPanel | Leaflet map with markers | ✅ Single purpose | +| `widgets/contacts_panel.py` | ContactsPanel | Contacts list + DM dialog | ✅ Single purpose | +| `widgets/message_input.py` | MessageInput | Message input + channel select | ✅ Single purpose | +| `widgets/message_list.py` | MessageList | Message feed + channel filter | ✅ Single purpose | +| `widgets/rx_log_panel.py` | RxLogPanel | RX log table | ✅ Single purpose | + +**SharedData:** 15 public methods in 5 categories (device updates, status, collections, snapshots, lookups). This is deliberate design: SharedData is the single source of truth between two threads. Splitting it would spread lock logic across multiple objects, making thread-safety harder. The responsibility is *"thread-safe data access"* — that is one reason to change. + +**DashboardPage:** After the widget decomposition, DashboardPage is now 148 lines with only 4 methods. It is a thin orchestrator that composes six widgets into a layout and drives the update timer. All rendering and data-update logic has been extracted into the widget classes. The previous ⚠️ for DashboardPage is resolved. + +**Conclusion SRP:** No violations. All classes have a single, well-defined responsibility. + +--- + +### O — Open/Closed Principle + +> "Open for extension, closed for modification." + +| Scenario | How to extend | Existing code modified? | +|----------|--------------|------------------------| +| Add new page | New module + `@ui.page` in entry point | Only entry point (1 line) | +| Add new BLE command | `_handle_command()` case | Only `ble_worker.py` | +| Add new contact type | `TYPE_ICONS/NAMES/LABELS` in config | Only `config.py` | +| Add new dashboard widget | New widget class + compose in DashboardPage | Only `main_page.py` | +| Add new route info | Extend RouteBuilder.build() | Only `route_builder.py` | + +**Where not ideal:** `_handle_command()` in BLEWorker is an if/elif chain. In a larger project, a Command pattern or dict-dispatch would be more appropriate. For 4 commands this is pragmatically correct. + +**Conclusion OCP:** Good. Extensions touch only one module. + +--- + +### L — Liskov Substitution Principle + +> "Subtypes must be substitutable for their base types." + +There is **no inheritance** in this project. All classes are concrete and standalone. This is correct for the project scale — there is no reason for a class hierarchy. + +**Where LSP does apply:** The Protocol interfaces (`SharedDataWriter`, `SharedDataReader`, `ContactLookup`, `SharedDataReadAndLookup`) define contracts that SharedData implements. Any object that satisfies these protocols can be substituted — for example a test stub. This is LSP via structural subtyping. + +**Conclusion LSP:** Satisfied via Protocol interfaces. No violations. + +--- + +### I — Interface Segregation Principle + +> "Clients should not be forced to depend on interfaces they do not use." + +| Client | Protocol | Methods visible | SharedData methods not visible | +|--------|----------|----------------|-------------------------------| +| BLEWorker | SharedDataWriter | 10 | 5 (snapshot, flags, GUI commands) | +| DashboardPage | SharedDataReader | 4 | 11 (all write methods) | +| RouteBuilder | ContactLookup | 1 | 14 (everything else) | +| RoutePage | SharedDataReadAndLookup | 5 | 10 (all write methods) | +| Widget classes | *(none — receive Dict/callback)* | 0 | 15 (all methods) | + +Each consumer sees **only the methods it needs**. The protocols enforce this at the type level. Widget classes go even further: they have zero knowledge of SharedData and receive only plain dictionaries and callbacks. + +**Conclusion ISP:** Satisfied. Each consumer depends on a narrow, purpose-built interface. + +--- + +### D — Dependency Inversion Principle + +> "Depend on abstractions, not on concretions." + +| Dependency | Before (protocols) | After (protocols) | +|-----------|---------------|---------------| +| BLEWorker → SharedData | Concrete ⚠️ | Protocol (SharedDataWriter) ✅ | +| DashboardPage → SharedData | Concrete ⚠️ | Protocol (SharedDataReader) ✅ | +| RouteBuilder → SharedData | Concrete ⚠️ | Protocol (ContactLookup) ✅ | +| RoutePage → SharedData | Concrete ⚠️ | Protocol (SharedDataReadAndLookup) ✅ | +| Widget classes → SharedData | N/A | No dependency at all ✅ | +| meshcore_gui.py → SharedData | Concrete | Concrete ✅ (composition root) | + +The **composition root** (`meshcore_gui.py`) is the only place that knows the concrete `SharedData` class. All other modules depend on protocols or receive plain data. This is standard DIP practice: the wiring layer knows the concretions, the business logic knows only abstractions. + +**Conclusion DIP:** Satisfied. Constructor injection was already present; now the abstractions are explicit. + +--- + +## 3. Protocol interface design + +### Why `typing.Protocol` and not `abc.ABC`? + +Python offers two approaches for defining interfaces: + +| Aspect | `abc.ABC` (nominal) | `typing.Protocol` (structural) | +|--------|---------------------|-------------------------------| +| Subclassing required | Yes (`class Foo(MyABC)`) | No | +| Duck typing compatible | No | Yes | +| Runtime checkable | Yes | Optional (`@runtime_checkable`) | +| Python version | 3.0+ | 3.8+ | + +Protocol was chosen because SharedData does not need to inherit from an abstract base class.
