Local Builds

DMC builds with PlatformIO. Building locally is useful to modify firmware, test pre-releases, or produce images that are not in Releases.

Tools

Install PlatformIO Core, or use the PlatformIO extension in VS Code.

Listing targets

Each env is a <board>_<role> combination. Envs are defined per board under variants/*/platformio.ini (the root platformio.ini pulls them in via extra_configs = variants/*/platformio.ini). List the available envs with:

pio project config

or browse the folders under variants/.

Building a target

pio run -e <env>

For example an observer build: pio run -e <board>_repeater_observer_mqtt. Observer envs are ESP32-only and gated on WITH_MQTT_BRIDGE.

Flashing

pio run -e <env> -t upload --upload-port <PORT>

<PORT> is COMx on Windows or /dev/ttyUSBx on Linux.

Monitoring

pio device monitor --port <PORT> --baud 115200

Release-style builds

build.sh produces branded artifacts with the distinctive version string v1.17.1.01-dutchmeshcore.nl-<hash>.
