GPSD

The gpsd service manages communication with the GPS and provides position and time information to applications that need it. It is configured to listen on port 2947 and can be queried by clients compatible with the gpsd protocol.

This service is automatically installed and started whether a GPS is present on the RecoveryBox or not. The service is configured to start even if no application is querying it. This ensures the GPS is always available for applications that need it, even if they haven't been launched yet.

Configuration file

/etc/default/gpsd

Chrony

The chrony service manages system time synchronization. By default, it uses public NTP servers to synchronize.

In the RecoveryBox, chrony is configured to use the GPS as the primary time source and provide accurate time to devices connected to the RecoveryBox.

Configuration file

/etc/chrony/000-gps.conf

Python Virtual Environment

A Python virtual environment is used to isolate RecoveryBox Python application dependencies. This avoids conflicts between different library versions and ensures each application has its own set of dependencies.

This virtual environment is created in the /data/recoverybox_env directory. It is used by the Meshtastic daemon and the wiki-generate.sh script. It is available for other Python applications if needed.

Binaries are available in the /data/recoverybox_env/bin directory. They can be used to run Python scripts or install additional packages in the virtual environment without activating it.

Activate the virtual environment

source /data/recoverybox_env/bin/activate

Deactivate the virtual environment
