## 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: Windows, Mac, and Ubuntu.

  ```bash title="Install Meshtastic Flasher"
  python3 --version
  # ensure you are using at least python v3.6
  # change to a directory where you want to create a python virtual environment
  mkdir some_dir
  cd some_dir
  # if the following command fails, it might tell you what package to install
  python3 -m venv venv
  # activate the python virtual environment
  source venv/bin/activate
  # your prompt should change - it should include "(venv) in the front
  # upgrade pip
  pip install --upgrade pip
  pip install meshtastic-flasher
  ```

  # open a command prompt
  # create a new directory for the python virtual environment
  cd c:\
  mkdir some_dir
  cd some_dir
  # check that python version is sufficient, must be at least v3.9+
  python -m venv venv
  # activate the python virtual environment
  venv\Scripts\activate

## 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
