MeshCore Signal Tester · Releases
from GitHub · updated 2026-07-106 releases
v1.2.3 # 10 days ago · 2026-07-10 15:51 UTC
Added
- Tap a point in a 2D chart to open that packet in the Received Packets table.
Changed
- 2D charts now follow live data while zoomed in — during measurement a zoomed SNR/RSSI chart keeps up with new packets at the right edge and stays within the recorded time range, instead of drifting onto old or empty time.
- The 2D-chart tooltip shows the time down to the millisecond and the packet type, plus how many receptions a clustered point stands for.
- Smoother, steadier 3D-map clustering — points no longer flicker or shuffle as you move or zoom the camera, more individual points are shown when you zoom into a sparse area, and points appear right after zooming in.
- Received Packets columns are ordered by recent activity — the most active repeaters lead, and columns with nothing in the newest packets no longer jump to the front (noticeable right after loading saved data).
- CSV export shows the saved file's size, and the notification's speaker icon appears as "(🔊)" when sound is set to "Disconnect only".
Fixed
- The 3D-map show/hide (eye) button now works for repeaters that share an ID prefix (collision columns).
- No more duplicate rows for the same repeater when it is seen at different ID lengths over a long run.
- The Received Packets table no longer clears when you open certain repeater columns.
- Seen Repeaters no longer scrolls on its own — it jumps to a repeater only when you select it.
- The "Load previously captured data?" prompt reliably appears when you reopen the app with saved data.
- "Show all repeaters" now works for loaded or long-running sessions — it places every known repeater that has a position, not only the ones that sent a packet in the recent in-memory window (previously it could do nothing even though each repeater still appeared when clicked individually).
- No more burst of queued beeps when you return to the app after it was in the background — per-packet sounds keep playing while the phone still allows audio, but once it suspends audio in the background they're skipped instead of piling up and all playing at once on return.
Internal
- Unit test suite (
node --test, 84 tests) covering CSV round-trips, the spatial index, tile/geo math, serial framing, repeater ID collision handling, the 3D-map LOD pyramid, and the chart zoom window — run automatically by a new GitHub Actions workflow on every push. - Several self-contained pieces of logic were extracted from
app.jsinto pure, tested modules:column-key.js(repeater ID prefix/collision semantics),frame.js(serial frame extraction),geo.js(map tile math),maplod.js(3D-map level-of-detail pyramid), andchart-zoom.js(live-follow zoom window). - Headless-browser regression harness (
tools/browser-check) that drives the real page in Chromium — imports a CSV and asserts the stats, column order, and "Show all repeaters" behave; used before every build.
v1.2.2 # 23 days ago · 2026-06-27 14:23 UTC
Added
- Import multiple CSV files at once — select several files and they're merged in a single import.
- 3D map keeps loading tiles while "Center on me" follows you — only while the map is on-screen and the app is in the foreground, to save data.
- Auto-reconnect after Bluetooth returns (for example after leaving airplane mode).
Changed
- Android 15 support with true edge-to-edge — the dark border around the UI is gone; content runs to the screen edges and stays scrollable to the very top.
- Android app package renamed to
cz.kyblsoft.meshcore.signaltester. It installs as a new app — the previous build is not replaced.
Fixed
- "Connected but no packets" after airplane mode — Bluetooth turning off is now detected as a disconnect instead of leaving the app stuck "connected".
- Tables no longer go blank after long runs — Seen Repeaters and Received Packets are restored from disk once old data ages out of memory.
- 3D map repeater icons are now correctly hidden behind signal balls in front of them, plus various other UI and chart fixes and polish.
Internal
- The
usb-serial-for-androidlibrary is vendored and built from source (no JitPack); the build is reproducible with pinned tooling and dependency checksum verification, and a CI workflow builds and lints the app on every change.
v1.2.1 # 28 days ago · 2026-06-22 15:32 UTC
Added
- Auto-reconnect — an optional toggle that automatically retries the last device after an unexpected drop, before the disconnect alarm. Shown only where it can actually work (not for Bluetooth in a mobile browser).
- Nicer packet sound — a pleasant bell whose pitch still tracks signal strength, plus a new "disconnect only" sound mode. The disconnect alarm now sounds on every unexpected drop.
Changed
- Location now starts automatically when you connect (Android) — no need to tap the 3D map's "Enable location" button anymore.
- Steadier location on the 3D map — occasional GPS jumps (sudden ~200 m hops) are filtered out.
- 3D map zooms in to street level even on large maps, and deep zoom is smoother.
- 3D camera framing — "Center on me" no longer jerks at the end of its move, and repeaters are framed with a little headroom above them.
Fixed
- 2D charts could stop updating with Display set to All, until you switched the Display window and back.
- Help (?) tooltips could appear away from their icon.
- Seen Repeaters now shows the true last RSSI/SNR, not a rounded/averaged value.
- Received Packets always lists every repeater as a column, not only the ones on the current page.
- 3D map selection no longer clears itself on its own.
- 3D map tiles no longer flicker while panning or zooming.
- Footer text now has proper contrast in light mode.
v1.2.0 # 1 month ago · 2026-06-14 12:24 UTC
Added
- Zoomable 2D signal charts — wheel or pinch to zoom the time axis, drag across a region to zoom in, drag/Shift+wheel to pan. Both charts stay aligned; double-click or Reset zoom to restore.
- Full capture history is now kept on disk, not just in memory — "Auto-remove: Never" keeps the whole session without slowing down or running out of memory, your data survives a reload or crash (it offers to resume on launch), every view is consistent across the Display window, and CSV export covers the complete history.
- More 3D map styles — CARTO (Dark Matter, Positron, Voyager, +no-label variants), Esri (Dark/Light Gray Canvas and satellite), more OpenStreetMap flavours, and a None (no map) option. In dark mode the area around the map is now black.
Changed
- Longer history durations — Auto-remove and Display now offer 3 h and 12 h (10 min and 30 min were removed).
- The 3D map's "Cluster radius" setting is gone — nearby points are grouped automatically based on zoom, so there's nothing to tune.
Fixed
- The Android app no longer freezes on a blank screen after running for hours, and recovers on its own if the system reclaims it in the background.
- Packets captured before location was turned on are no longer placed at your current location on the 3D map — position-less points aren't shown; CSV import likewise never assigns the current location to rows that have none.
- Connecting to a saved Bluetooth device while Bluetooth is off now prompts you to turn it on instead of silently never connecting.
- A Bluetooth device you renamed after saving it now connects under, and is re-saved with, its new name.
- Better light/dark readability — the map's location-status text, the 3D-map fullscreen button, the packet detail panel and the page footer are now legible in both themes; map buttons no longer look stuck-pressed after a tap.
v1.1.0 # 1 month ago · 2026-06-07 06:32 UTC
Added
- Connect over USB — plug a companion radio in with a USB cable instead of using Bluetooth. Devices you've connected to before show up as buttons for one-tap reconnecting.
- Repeater support — you can now plug a MeshCore repeater into USB, not just a companion radio; the app detects which kind it is on its own. With special logging firmware it shows full detail for every packet; with normal firmware it shows what it can read from the repeater's logs.
- Connect over WiFi (Android app only) — reach a WiFi companion over your network by typing in its IP address. Web browsers can't do this, so it works only in the Android app.
- Android app niceties — it now shows the current status in the phone's notification bar (with a speaker icon while beep alerts are on, and a "paused" marker when capture is stopped), opens web links in your normal browser, and closes pop-ups when you press Back.
- 3D map additions:
- optionally show your own device's location on the map (off by default — while on it keeps asking the device for its position, which can drain the battery faster, so leave it off when you don't need it);
- a Center on me button that recentres the map and then follows you as you move;
- pin repeaters to the map and point the camera at one;
- while capturing, the map keeps the area around you loaded so you don't drift off the edge.
- Disconnect warning — a clear full-screen alert if the connection drops unexpectedly (cable unplugged, device reset, out of range). It stays quiet when you disconnect on purpose.
Changed
- Tidier header — the connect/disconnect buttons and the status are grouped into one colour-coded box (red when disconnected, green when connected).
- Sound is easier to notice — when the beep-on-each-packet sound is turned on, its control turns yellow so you can see at a glance that it's on.
- Clearer repeater colors — brighter and easier to tell apart.
Fixed
- Trace packets now show the correct route (they used to show the wrong path).
- Your contacts list no longer sometimes fails to finish loading.
- The 3D map's "Enable location" button no longer freezes when your phone's location is switched off — it works again once you turn location back on.
- The same Bluetooth device no longer shows up several times in your list of saved devices.
- The 3D map's fullscreen button now works in the Android app (it did nothing there before).
Plus lots of smaller improvements throughout.
