Prerequisites
Device connectivity
Ensure your computer is communicating with the device correctly by following these instructions.
Download Latest Firmware
Firmware can be downloaded from the Downloads page. Your initial installation has to happen over USB from your Mac, Windows, or Linux computer. Over the air updates are currently only available using the Android application after this initial installation.
:::note The T-Beam 0.7 board is an earlier version of the T-Beam board, and due to changes in the design in subsequent iterations this board uses a specific firmware file different from the other T-Beam boards.
firmware-tbeam0.7-1.x.x.bin is the correct firmware. firmware-tbeam-1.x.x.bin is incompatible. For all other T-Beam boards firmware-tbeam-1.x.x.bin is the correct selection.

Command Line Interface Instructions
<Tabs groupId="operating-system" defaultValue="linux" values={[ {label: 'Linux', value: 'linux'}, {label: 'macOS', value: 'macos'}, {label: 'Windows', value: 'windows'}, ]}>
Install Prerequisite Software
Check if you have python3 and pip installed with the following command
python3 --version
pip3 --version
If python3 is not installed, install with
sudo apt-get update
sudo apt-get install python3
If pip is not installed, install with
sudo apt-get install python3-pip
Install esptool
pip3 install --upgrade esptool
Install Prerequisite Software
OS X comes with Python 2.7 installed, but not pip. The following uses Homebrew to install python3 which includes pip3. On MacOS you will use pip3 instead > of pip.
:::note Check if you have Homebrew installed with the following command
brew -v
If it's not installed, follow the instructions on the Homebrew website before continuing. :::
Check if you have python3 and pip installed with the following command
python3 --version
pip3 --version
If python3 is not installed, install with
Install Python3
brew install python3
Confirm pip3 was installed alongside python3
pip3 -v
Install esptool
pip3 install --upgrade esptool
- Download and install Python. When installing, make sure to click
Add Python X.Y to PATH. - Download and install Gitbash (or other appropriate shell) and run all subsequent commands from that shell.
:::note
Confirm installation of python & pip with the following commands.
py --version
pip --version
:::
Install esptool
pip install --upgrade esptool
Confirm Communication With Chip
<Tabs groupId="operating-system" defaultValue="linux" values={[ {label: 'Linux', value: 'linux'}, {label: 'macOS', value: 'macos'}, {label: 'Windows', value: 'windows'}, ]}>
:::important
On Windows, you must explicitly declare esptool as a .py script. Use esptool.py chip_id.
:::
Connect the radio to your computer using a data USB cable. Confirm your device is talking to your computer using the following command:
esptool chip_id
# You should see a result similar to this:
mydir$ esptool chip_id
esptool.py v2.6

Navigate to Firmware
cd into the directory where you unzipped the latest release. For example:
cd ~/Downloads/firmware/
Install/Update Firmware
Install or Update the device that you have by using the following commands according to your operating system:
:::caution Be very careful to install the correct load for your board. In particular the popular 'T-BEAM' radio from TTGO is not called 'TTGO-Lora' (that is a different board). So don't install the 'TTGO-Lora' build on a TBEAM, it won't work correctly. :::

Select Firmware
Browse to the previously downloaded firmware and select the correct firmware based on the board type and frequency.
:::caution Be very careful to install the correct load for your board. In particular the popular 'T-BEAM' radio from TTGO is not called 'TTGO-Lora' (that is a different board). So don't install the 'TTGO-Lora' build on a TBEAM, it won't work correctly. If you flash the incorrect firmware: It may appear to flash correctly, but if your device has a screen it might stay blank. On-board radio peripherals might be damaged because of GPIO pin direction, but you should just try to flash with the correct version. :::
Flash Firmware
Select Flash ESP. It may take a minute or two. Once complete, "Done! Flashing is complete!" will be shown.
Over the Air Update Instructions
OTA updates are only currently available on Android.
