## Overview

Meshtastic Flasher is a graphical user interface for flashing [supported devices](/docs/hardware) with Meshtastic.

## Prerequisites

Install Meshtastic Flasher by either [downloading the executable file](https://github.com/meshtastic/Meshtastic-gui-installer/releases) or installing using `pip`. The following operating systems are currently supported: Windows, Mac, and Ubuntu.

### Check Data Cable

Plug your device into your computer using a USB cable and then do the following:
:::important
You may need to install a driver from Silicon Labs for the [CP210X USB to UART bridge](https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers)

Some newer boards may require the drivers for the [CH9102 Windows](http://www.wch.cn/downloads/CH343SER_ZIP.html) or [Direct Download](https://github.com/Xinyuan-LilyGO/CH9102_Driver) for Windows 7. For [CH9102 Mac](http://www.wch.cn/downloads/CH34XSER_MAC_ZIP.html). Click the big blue button with the down arrow. Be sure to open up the application and click "Install" after the package is installed. Also, reboot.

Connect your Meshtastic device to your USB port, open a `Terminal` and enter the following command:

```bash
lsusb
```

You should see something like: `ID 10c4:ea60 Silicon Labs CP210x UART Bridge` for CP210X or `ID 1a86:55d4 QinHeng Electronics USB Single Serial` for CH9102

## Flashing the Device

The Meshtastic Flasher will flash the latest firmware to esp32 and nrf52 devices. This is a newly developed application (as of February 1, 2022), so there may be some issues discovered as it is tested by users.

There are three steps:

* Click the "GET VERSIONS" button to get the versions available (from GitHub).
* Click the "DETECT DEVICE" button to determine the port and device variant connected.
* Click the "FLASH" button to flash the version selected, using the port selected to the device.

## Issues?

If you run into an issue, please create a ticket here: [Flasher Issues](https://github.com/meshtastic/Meshtastic-gui-installer/issues)

The code can be found at the [Meshtastic-gui-installer repo](https://github.com/meshtastic/Meshtastic-gui-installer)

## Known limitations

The following are known limitations:

* Raspberry Pi is not available, since it is arm-based and there are no pre-built libraries for [PySide](https://wiki.qt.io/Qt_for_Python)
* Ubuntu 20.04 is the version used for testing, it may work with other versions
* see [README](https://github.com/meshtastic/Meshtastic-gui-installer/blob/master/README.md) for more details
