# Seeed Wio Tracker Setup Guide

<div id="bkmrk-%E2%9A%A0-antenna-safety-%E2%80%94-a" style="background:#fff3cd;border:2px solid #ffc107;padding:12px 16px;margin-bottom:20px;">**⚠ ANTENNA SAFETY - ALL DEVICES:** Always connect an antenna **before** powering on or transmitting with any LoRa device. Transmitting without an antenna can damage the radio. SX1262-based boards (like the Wio Tracker) are relatively low-power and tolerate brief antenna mismatches better than older parts, and simply powering the board on without transmitting is generally harmless - but never deliberately transmit without an antenna connected. </div>## Seeed Wio Tracker L1 - Setup Guide

The Seeed **Wio Tracker L1** is an nRF52840-based Meshtastic node with an SX1262 LoRa radio, an L76K multi-GNSS (GPS) module, and a 1.3" OLED display. The **L1 Pro**variant adds an enclosure and an integrated battery - strongly recommended for field deployment over the bare L1 board.

A note on naming, since Seeed's lineup is easy to confuse: the **Wio Tracker L1** is the bare board used for this build; the **L1 Pro** is the L1 plus an enclosure and integrated battery. These are distinct from the separate **Wio Tracker 1110**, which is a different LR1110-based development board - it is **not** the same product as the L1, so match the exact name to the store listing before you buy.

Most users deploying in the field should choose the **L1 Pro**, which ships as a ready-to-use node with an enclosure and an integrated battery. </div>### Driver Installation

**No driver installation required on any operating system.** The nRF52840 presents as a USB mass storage device. It appears automatically on Windows, macOS, and Linux.

### Entering Bootloader / DFU Mode

1. Connect the device via USB.
2. Locate the **RESET button** (may be recessed - use a SIM card ejector pin, toothpick, or similar small tool).
3. **Double-tap the RESET button** quickly.
4. The device will appear as a USB drive.

If the USB drive does not appear, retry the double-tap - timing sensitivity is similar to the T-Echo.

### Firmware Flashing

**Method A - Web Flasher (recommended):**

1. Enter DFU mode (double-tap RESET).
2. Open Chrome or Edge and navigate to: 
    - **MeshCore:** [flasher.meshcore.io](https://flasher.meshcore.io)
    - **Meshtastic:** [flasher.meshtastic.org](https://flasher.meshtastic.org)
3. Select the **Wio Tracker L1** variant from the device list.
4. Click **Flash**.

**Method B - Drag and Drop:**

1. Download the `.uf2` firmware file.
2. Enter DFU mode.
3. Drag and drop the `.uf2` file onto the USB drive.
4. Device reboots automatically.

### Post-Flash Configuration

1. GPS begins acquiring satellites automatically after boot.
2. Connect via Bluetooth app and set **region to US**.
3. Configure node name and channel settings.

### Known Quirks

- The RESET button may be recessed - have a SIM pin or similar tool available.
- GPS first fix may take several minutes on a fresh boot outdoors.
- L1 bare board requires an external battery and enclosure for practical field use.
