Development

There should be mqtt broker available on the host system. If not, there is a docker image for that:

docker run -d --name mosquitto --restart unless-stopped -p 1883:1883 registry.gitlab.com/roxautomation/images/mosquitto:latest

• Open in VSCode devcontainer. Virtual com port is located at /tty/tty_nmea_rx
• Pre-recorded nmea stream can be sent to com port with replay_data.py in integration/data folder.

TODO

Current setup works, but it can always be made better.

• add tests
• Use uart ports instead of usb. This will make system more robust.
