Custom firmware/program name¶

Sometimes it is useful to have a different firmware/program name in build_dir. The following example uses Custom options in platformio.ini and adds a project version suffix to the firmware name.

platformio.ini:

[env:env_custom_prog_name]
platform = espressif32
framework = arduino
board = esp32dev
build_flags =
    -DVERSION=${this.custom_prog_version}
extra_scripts = pre:extra_script.py
custom_prog_version = 1.2.3

extra_script.py:

Import("env")

env.Replace(PROGNAME="firmware_%s" % env.GetProjectOption("custom_prog_version"))
