The app offers two complementary approaches:
โข Local Mesh Discovery (Scanner) โ an automated mode that cycles your connected radio through different LoRa presets, listens on each, and ranks which preset performs best at your location.
โข Manual exploration โ traceroute, Neighbor Info, and the node list, which you can use at any time to investigate specific paths and topology.
Local Mesh Discovery (Scanner)
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 โ Advanced โ Local Mesh Discovery. On desktop, it has its own Settings โ Local Mesh Discovery entry.
โ โ ๏ธ Note: Discovery temporarily changes your radio's LoRa settings while it scans, then restores
โ your original configuration when it finishes. Your device must be connected to run a scan.
Setting Up a Scan
Before starting, configure these controls:

โ LoRa preset picker โ Select one or more presets to scan. Discovery dwells on each selected presโฆ โ
โ Dwell time โ Time to listen on each preset. Choose from 1, 5, 15, 30, 45, 60, 90, 120, โฆ โ
โ Keep screen awake โ Optional toggle that prevents the screen from sleeping during a long scan. โ

The Start button stays disabled โ with an explanation of why โ until the scan can run. Common reasons it's disabled:
โข The device is not connected.
โข No presets have been selected to scan.
โข The selected preset uses 2.4 GHz, which your hardware doesn't support.
Live Progress
While a scan runs, Discovery shows its current stage:

โ Preparing โ Saving your current configuration and getting ready to scan. โ
โ Shifting to <preset> โ Switching the radio to the next preset to test. โ
โ Reconnecting โ Re-establishing the connection after the preset change. โ

Additional features available from the results:
โข Scan History โ saved sessions you can revisit; view or delete past scans.
โข Discovery Map โ a map of the nodes found during the scan.
โข Report export โ export a report as a PDF on Android, or as text on other platforms.
โ ๐ก Tip: On Android, Discovery can generate an on-device AI summary (Gemini Nano) of your results.
โ If the on-device model isn't available, an algorithmic summary is used instead โ so you always
โ get a readable interpretation of the scan.
Mesh Beacon
Mesh Beacon lets nodes invite others to join their mesh. A beaconing node periodically broadcasts an invitation โ optionally advertising a channel, region, and modem preset โ that nearby devices can hear even before they share a configuration.
Configure it under Settings โ Module Config โ Mesh Beacon:
โข Listen for beacons โ receive invitations broadcast by other nodes.
โข Broadcast beacon โ send your own invitation at a set interval, with an optional message and an offered channel.
Received invitations appear as Mesh invitations cards on the Discovery screen. Each card shows the sender's message plus the offered channel, region, preset, and signal quality, with these actions:
โข Join โ switch to the offered channel and preset (retunes the radio and reboots). When the offer matches your current frequency slot, an Add channel action adds it without a reboot.
โข Discover โ seed a Discovery scan with the offered preset so you can survey that mesh before joining (shown only when the beacon offers a preset).
โข Dismiss โ ignore the invitation.
Channels advertised by beacons also show up in the scan setup as Beacon channels โ select one to include it as a scan target.
Manual Exploration
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.
