## Recovery one-liners
|
||||
|
||||
- **`userPrefs.jsonc` dirty after a test run?** Re-run `./mcp-server/run-tests.sh` once (pre-flight self-heals from the sidecar). If still dirty: `git checkout userPrefs.jsonc`.
|
||||
- **nRF52 not responding?** `mcp__meshtastic__touch_1200bps(port=...)` drops it into the DFU bootloader, then `pio_flash` re-installs.
|
||||
- **Device fully wedged (no DFU)?** `mcp__meshtastic__uhubctl_cycle(role="nrf52", confirm=True)` hard-power-cycles it via USB hub PPPS. Needs `uhubctl` installed (`brew install uhubctl` / `apt install uhubctl`); on Linux without udev rules, permission errors fail fast, so use `sudo uhubctl` yourself or configure udev access.
|
||||
- **Port busy?** `lsof <port>` to find the holder. Usually a stale `pio device monitor` or zombie `meshtastic_mcp` process. Kill it.
|
||||
- **Multiple MCP servers running?** `ps aux | grep meshtastic_mcp` — zombies hold ports. Kill all but the one your host spawned.

## Environment variables (test harness)
|
||||
|
||||
| Var | Purpose |
|
||||
| ------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| `MESHTASTIC_MCP_ENV_<ROLE>` | Override PlatformIO env for a role (e.g. `MESHTASTIC_MCP_ENV_NRF52=rak4631-dap`). Default map: `nrf52→rak4631`, `esp32s3→heltec-v3`. |
|
||||
| `MESHTASTIC_MCP_SEED` | PSK seed for the session test profile. Defaults to `mcp-<user>-<host>`. |
|
||||
| `MESHTASTIC_MCP_FLASH_LOG` | File path to tee pio/esptool/nrfutil/picotool output. `run-tests.sh` sets this to `tests/flash.log` so the TUI can stream live flash progress. |
|
||||
| `MESHTASTIC_UHUBCTL_BIN` | Absolute path to `uhubctl` binary. Default: PATH lookup. |
|
||||
| `MESHTASTIC_UHUBCTL_LOCATION_<ROLE>` | Pin a role to a specific uhubctl hub location (e.g. `1-1.3`). Wins over VID auto-detection — use when multiple devices share a VID. |
|
||||
| `MESHTASTIC_UHUBCTL_PORT_<ROLE>` | Pin a role to a specific hub port number. Required alongside `LOCATION_<ROLE>`. |
|
||||
| `MESHTASTIC_UI_CAMERA_BACKEND` | Camera backend for UI tier + `capture_screen` tool: `opencv` / `ffmpeg` / `null` / `auto` (default). |
|
||||
| `MESHTASTIC_UI_CAMERA_DEVICE` | Generic camera device (index or path). Used by the UI tier when no per-role var is set. |
|
||||
| `MESHTASTIC_UI_CAMERA_DEVICE_<ROLE>` | Per-role camera pinning (e.g. `MESHTASTIC_UI_CAMERA_DEVICE_ESP32S3=0` for the OLED-bearing heltec-v3). |
|
||||
| `MESHTASTIC_UI_OCR_BACKEND` | OCR engine selection: `easyocr` / `pytesseract` / `null` / `auto` (default). |
|
||||
| `MESHTASTIC_UI_TUI_CAMERA` | Set to `1` to mount the live camera-feed panel in `meshtastic-mcp-test-tui`. |
