Test build. Stable stays beta_50.

The big one: WADAMESH runs apps written in Lua now, installed from a Store on the device and updated over the air without reflashing. The runtime, the API, the Store and the first converted apps all ship together in this tag.

Flash it from https://flasher.wadamesh.com (flip the Beta toggle), or on-device via Settings → Firmware with "Get test builds (beta)" enabled.

Lua apps

An app is a single .lua file. It installs from the Store, appears in the app drawer beside the built-ins, and updates when a newer version lands in the catalog — no firmware flash involved.

Store lives in the app drawer, with three tabs:

  • Apps — install, update or remove what the catalog offers.
  • Built-in — hide the stock apps you never open, so the drawer holds what you actually reach for. The MQTT bridge is hidden by default now.
  • Languages — download translations (see below).

RF Monitor and Airtime are Lua apps rather than firmware pages, and they gained things the native versions never had: RF Monitor scrolls the full packet list, Airtime has proper Y-axis labels and a Reset button. Snake is a Lua app too. Removing one really removes it; reinstalling brings it back with your scores intact.

Write your own. Drop a bare .lua file into /apps/ on the card and it appears in the drawer — no manifest needed. The API is about thirty functions covering the screen, input, read-only mesh data, an HTTP fetch and a little per-app storage.

📖 API reference: https://wadamesh.com/sdk.html

Two constraints worth knowing up front. The mesh is read-only in v1 — an app can read contacts, the packet log and radio statistics, but cannot transmit; a buggy or hostile app must not be able to put packets on the air in your name. And http_get is plain HTTP, because after Wi-Fi associates there is not enough internal heap left for a TLS handshake on the smaller boards.

Languages are files now

Translations are no longer baked into the firmware. They download from the Store's Languages tab as versioned files, so a translation can be fixed and shipped without waiting for a firmware release — the device offers Update when a newer one exists.

Every language got a full sweep: roughly 150 strings that had quietly stayed English for months — the channel settings sheets, the message menus, most buttons — are translated across all 13 languages. Settings → Language opens the Languages tab directly, and switching one now tells you it is restarting before it does, instead of rebooting under your finger.

Heltec V4

The V4 has 2 MB of PSRAM and very little free internal memory, which made the Store unreliable there. It now ships every language and every catalog app inside the firmware image — the apps are in the drawer on first boot and all 13 languages are already installed. Its Store is a picker rather than a shop.

Around 17 KB of internal memory reclaimed on the V4, measured step by step: the store and Discover tables moved out of static memory, and the allocator now places ordinary allocations in PSRAM instead of forcing everything under 4 KB into internal RAM.

Fixes

  • "Save update bin to SD" works again. It failed with "SD write failed" at 1–7% on every T-Deck and had been broken since the feature shipped in beta_36. The download buffer sat in PSRAM, which the SD card cannot reliably DMA from, so the write died partway through at a point that moved with the network. Nothing to do with card size or formatting. Reported by Marshal W7TER, df2080 and Dennis.
  • The same defect is fixed in two places nobody had hit yet: copying any file to the SD card from the Files app, and exporting a crash dump.
  • The Store fits narrow and high-DPI screens. Cards measure their own text instead of assuming two lines, so nothing is cut off and a long title no longer lands on top of the description. This also fixes every board for languages whose text runs longer than the English.
  • Installing an app or language shows a spinner on the button for the whole download instead of a brief message, so a slow connection no longer looks like the tap did nothing.
  • Opening the app drawer and the Store is quicker — the card was being re-scanned on the UI thread every time the drawer opened.

Both P4 panel variants are built fresh for this tag: wadamesh-tdisplay-p4* (AMOLED) and wadamesh-tdisplay-p4-lcd* (TFT-LCD).
