SIMPLE STEPS

Update or start fresh

Use desktop Chrome or Edge and a USB data cable. Close other serial tools. Connect one MAR at a time. Keep USB connected while flashing.

Update — keep settings

  1. Choose your board’s firmware above.
  2. Connect USB, check the board confirmation and click Connect & identify. Select MAR’s COM port.
  3. Click Flash update — keep settings and confirm.
  4. Wait for verification. Press RESET if needed, then open your MAR dashboard and review Device settings.

Updates require a recognized MAR build for the same board and partition layout. Both application slots are replaced; saved-data areas are checked unchanged. If rejected, nothing is written. Older 2.0 portals may reject 2.1 filenames—use this USB updater. Never rename the other board’s image.

Full flash — erase settings

  1. Choose your board’s firmware, connect USB and click Connect & identify.
  2. Check the full-erase box and click Full flash — erase settings.
  3. Wait for verification, then press RESET if needed. Allow a few seconds to start.
  4. Join MeshAutoResponder-Setup with ESP32MESH. Open http://192.168.4.1/wifi to set Wi-Fi, or http://192.168.4.1/ for the dashboard.

Full flash removes saved Wi-Fi, commands and settings. Use it for a fresh install or a deliberate clean reset.

Can’t find the port or setup Wi-Fi?

Hold BOOT, tap RESET, then release BOOT. Reconnect using the boot-mode COM port, which may be different. After flashing, press RESET normally.

In 2.1, press BOOT to open setup Wi-Fi and wake the screen. Wi-Fi stays enabled. BOOT opens the setup hotspot when needed. The dashboard needs no login by default; the hotspot password is still ESP32MESH. If you enable dashboard login, a fresh installation uses admin / ESP32MESH; an update retains your saved password. MAR 1.1.1 still requires its dashboard login.

The browser identifies the ESP32-S3 and flash size, but cannot verify LCD wiring or PSRAM. Select the matching board pane.

Use DMs or private channels for automated responses.

Enable Primary responses only for a deliberately managed infrastructure node. Be considerate of other users on the mesh.
