wadamesh beta_10 — flash from https://flasher.wadamesh.com, or update on-device (Settings → About).
What's new
T-Deck input
- Trackball mode — switch the T-Deck trackball between a mouse cursor (the default) and D-pad navigation (roll to move the selection, click to choose), under Settings → Keyboard. Handy if you prefer button-style navigation.
Map — #20
- microSD tiles now fill in as you explore. With Use microSD for tiles on, the device also downloads any missing tiles over Wi-Fi and saves them straight onto the SD card, so your offline library grows instead of showing blank areas past its edge. Thanks @1nerdherder (#20).
Power — by @Vybo (#19)
- Experimental battery saver (idle power-save). Throttles the CPU when the device is parked — screen off, on battery, no app connected and the mesh quiet — to trim idle power use, without ever missing a received packet. Off by default; enable under Settings → System → Battery. (#19)
Settings
- New "Battery" section under Settings → System — opens the battery & power-history screen (the same one you get by tapping the battery icon up top), and is where the battery saver now lives (it moved out of the Lock settings).
🙏 Thanks to Dan Vybiral (@Vybo) for the idle power-save feature (#19) and @1nerdherder for the microSD-tiles report (#20).

wadamesh beta_9
A reliability-focused drop — Wi-Fi recovery, a self-healing chat-history fix, crash-report export, plus room-server, map, contacts and app-drawer improvements.
Install / update: flash from flasher.wadamesh.com, grab it in LauncherHub, or use the on-device update check (Settings → About).
Stability
- Wi-Fi now reconnects on its own after the link drops — no more rebooting to get back online.
- Fixed reboot-on-every-received-message: a corrupted chat-history file could make the device reboot whenever a message arrived (and hide your messages). The bad file is now detected and reset automatically, so it recovers on its own.
- Boot hardening: NULL-guards on the display draw buffer so a unit with quirky/limited memory degrades gracefully instead of getting stuck on the boot logo.
Crash reports
- After a crash, Settings → About shows an "Export crash report" button that saves the crash dump to the microSD card — so you can send it to the devs and get the bug fixed.
Chat & room servers
- Room-server messages now show the time each message was actually sent, not when it arrived.
- Room-server messages now show who sent them.
- Sharing your contact QR now produces a valid
meshcore://contact/add?…code that the MeshCore phone app can scan and import. - Unread counts show "99+" instead of an alarming raw number on busy channels.
Map
- The reload button for corrupt tiles now actually clears the cached tiles — including when you're offline — and the missing/blank "twilight zone" tiles re-download on their own.
- Fixed tiles not re-fetching at zoom levels 13–15.
Contacts
- Favourited contacts always appear in the contact list now, even with hundreds of similarly-named contacts (they used to stay hidden until you searched).
App drawer
- New icon-size setting — tap the cog at the top-right of the app drawer to switch between Compact and Large (bigger icons + labels, easier to read).
- Smoother scrolling through the app list and the other scrollable lists.

wadamesh beta_8
Polish + fixes for the touch UI — a faster chat acknowledgement, map readout controls, and an internal-memory trim.
Install / update: flash from flasher.wadamesh.com, grab it in LauncherHub, or use the on-device update check (Settings → About).
Chat
- Quick replies insert at the cursor instead of replacing whatever you'd already typed.
- New one-tap "Ack" — long-press any message and tap Ack. It drops a ready-to-send reply into the composer with that message's signal strength (SNR/RSSI) and the route it took (hop codes), so you can instantly confirm someone's test came through. On a channel it
@-mentions the sender. You review and send — it's never auto-sent. - Fixed the message action menu (Ack / Copy / Info / Mention / Block) running off the bottom of the screen — it now fits, and scrolls if it ever needs to.
Map
- The zoom button now shows a clear "+/-" icon.
- Show or hide each on-map readout independently in Map settings — the coordinates line, the tile x/y/z line, and the contact markers.
- Map settings reorganised: the microSD-tiles switch sits at the top under its own heading, separated from the new visibility toggles.
- New auto-refresh button — turn it on and the map re-centres on you automatically whenever your position changes, with an on-screen Auto-refresh on/off confirmation.
- Fixed the close (X) in Map settings overlapping the switches when the panel was scrolled.
Performance
- Reclaimed ~19 KB of internal RAM (scratch buffers moved to PSRAM), leaving more headroom for Wi-Fi and trimming the idle-memory growth seen in recent betas.
