mudp 1.0.0a7

A library for Meshtastic communication over UDP.

This library provides UDP-based broadcasting of Meshtastic-compatible packets.

Installation

pip install mudp

Command Line

To view all Meshtastic udp activity on your LAN:

mudp

PubSub RX Topics

When using this library as a listener, it can publish received packets to the Python pubsub system. The following topics are available:

• mesh.rx.raw – publishes (data, addr) with the raw UDP packet bytes and source address tuple.
• mesh.rx.decode_error – publishes (addr) when a packet fails to decode.
• mesh.rx.packet – publishes (packet, addr) for all successfully parsed MeshPacket objects.
• mesh.rx.decoded – publishes (packet, portnum, addr) when the decoded portion is available.
• mesh.rx.port.<portnum> – publishes (packet, addr) for filtering by port number.

Send Functions (see examples for further information):
