# Open-source interoperability notice

Mesh Guard is closed-source PX7 software. It does not embed or link Meshtastic protocol code or SwiftProtobuf.

Optional Meshtastic compatibility is provided by the separately installed **PX7 Meshtastic Bridge** executable. That independent process contains Meshtastic protocol definitions and generated sources under GNU GPL version 3 and Apple SwiftProtobuf under the Apache License 2.0. Its license, corresponding source and build instructions are distributed with the bridge.

Mesh Guard communicates with the bridge only through a documented, versioned JSON-lines protocol over the child process's standard input and output.

Mesh Guard is independent software compatible with Meshtastic. It is not affiliated with or endorsed by the Meshtastic project.
