description: Explore your mesh network — the Local Mesh Discovery scanner, traceroute paths, neighbor maps, and node discovery tools.

aliases:

• mesh-discovery

• local-discovery

• network-scan

• traceroute

• neighbor-info

Инструменты обнаружения помогают понять, как твоя mesh-сетевая структура соединена — какие ноды могут слышать друг друга, по каким путям проходят сообщения и где существуют узкие места или слабые звенья.

The app offers two complementary approaches:

• Local Mesh Discovery (Scanner) — an automated mode that cycles your connected radio through different LoRa presets, listens on each, and ranks which preset performs best at your location.

• Manual exploration — traceroute, Neighbor Info, and the node list, which you can use at any time to investigate specific paths and topology.

Local Mesh Discovery is a dedicated scanning mode that helps you find the best LoRa modem preset for your location and see which nodes are active on each preset. It cycles your connected radio through one or more presets you choose, listens (or "dwells") on each one for a set time to collect packets, then analyzes and ranks the results.

Open it from Settings → Local Mesh Discovery.

│ ⚠️ Note: Discovery temporarily changes your radio's LoRa settings while it scans, then restores

│ your original configuration when it finishes. Your device must be connected to run a scan.

Before starting, configure these controls:

The Start button stays disabled — with an explanation of why — until the scan can run. Common reasons it's disabled:

• The device is not connected.

• No presets have been selected to scan.

• The selected preset uses 2.4 GHz, which your hardware doesn't support.

While a scan runs, Discovery shows its current stage:

When the scan completes, Discovery presents a per-preset result card for each preset it tested, plus an overall summary.

Metrics include:

Additional features available from the results:

• Scan History — saved sessions you can revisit; view or delete past scans.

• Discovery Map — a map of the nodes found during the scan.

• Report export — export a report as a PDF on Android, or as text on other platforms.

│ 💡 Tip: On Android, Discovery can generate an on-device AI summary (Gemini Nano) of your results.

│ If the on-device model isn't available, an algorithmic summary is used instead — so you always

│ get a readable interpretation of the scan.

The tools below are available at any time from the node list and node detail screens. Use them to investigate specific paths and build a topology picture, alongside or instead of a full scan.

Трассировка показывает точный путь, который сообщение проходит от твоей ноды до любой другой ноды в сети. Это самый полезный инструмент для отладки проблем с подключением.

1. Перейди в Ноды и коснись ноды, которую ты хочешь отследить.

2. На экране деталей ноды нажми Трассировка.

3. Приложение отправляет запрос трассировки и ожидает ответа.

4. Результаты отображают каждую ноду по порядку с качеством сигнала на каждом этапе.

Результат трассировки выглядит так:

T282828

Каждый хоп представляет собой ретранслирующую ноду, которая переслала сообщение. Значения SNR и RSSI на каждой ноде говорят о качестве соединения на этом конкретном участке.

│ 💡 Совет: Запусти трассировку несколько раз в течение нескольких минут. Если путь изменяется, у

│ твоей сети есть лишние маршруты — признак хорошо связанной сети.

• ''Маршрут не найден'' — Целевая нода может быть оффлайн, находиться вне зоны действия или на другом канале. Проверь, что обе ноды имеют хотя бы один канал с одинаковым ключом шифрования.

• Время ожидания трассировки истекло — путь может быть слишком длинным (превышен лимит хопов) или нода ретрансляции перегружена. Попробуй увеличить лимит хопов в Настройки → Конфигурация LoRa.

• Асимметричные маршруты — трассировка от A→B может проходить по другому пути, чем B→A. This is normal — radio propagation is not always symmetric.

The Neighbor Info module lets each node broadcast a list of the nodes it can directly hear (single-hop). When multiple nodes share their neighbor lists, you can piece together a topology map of the entire mesh.

1. Перейдите в Настройки → Конфигурация модуля → Информация о соседях.

2. Включение модуля

3. Set the broadcast interval (default: 900 seconds / 15 minutes).

Once enabled, your node periodically broadcasts its neighbor table. Other nodes with Neighbor Info enabled do the same.

• Open any node's detail screen and look for the Neighbors section.

• Each neighbor entry shows the node that was directly heard and its signal quality.

• Combine neighbor data from multiple nodes to understand the full mesh topology.

│ ⚠️ Note: Neighbor Info increases airtime usage because every enabled node periodically broadcasts

│ its neighbor list. On busy meshes with many nodes, consider longer broadcast intervals (3600

│ seconds or more) to avoid congestion.

The node list itself is a powerful discovery tool when you use its filtering and sorting features effectively.

• Sort by Last heard to see the most recently active nodes at the top.

• Enable Include unknown to see nodes that have appeared on the mesh but haven't sent user info yet — these are often newly powered-on devices.

• Sort by Hops away to see which nodes are directly reachable (0 hops) versus relayed.

• Sort by Distance to find nearby nodes and verify they're reachable.

• Use Exclude MQTT to focus on nodes reachable over radio (not via internet bridge).

• Disable Exclude infrastructure to see Router, Repeater, Router Late, and Client Base nodes.

• Check their signal quality and last-heard times to verify your infrastructure nodes are healthy.

See Nodes for full details on filtering and sorting options.

• Start with traceroute — it gives you immediate, actionable information about a specific path.

• Enable Neighbor Info on key nodes — especially routers and repeaters, to build a picture of the backbone.

• Check the map — node positions on the Map combined with signal data help you understand why some links are strong and others are weak.

• Compare signal over time — use the Signal Meter guide to interpret SNR and RSSI values correctly.
