TapTap Firmware for MeshCore

February 7, 2026 · View on GitHub

TapTap Firmware is a specialized build of MeshCore designed for tracker-style devices like the Seeed Studio T1000-E and WisMesh Tag. It introduces enhanced messaging capabilities and specific button interactions tailored for headless operation (devices without screens).

  • Double Click: Enter Canned Message Mode.
    • Single Click: Cycle through the 8 preset messages.

    • Auto-exit: If no action is taken for 10 seconds, the device will automatically exit this mode.
  • Triple Click: Toggle GPS functionalities on/off to save power.
