MeshService::injectAsReceived (gated by MESHTASTIC_ENABLE_FRAME_INJECTION, off by default) extends the portduino SimRadio SIMULATOR_APP path to real hardware: a client-supplied frame, wrapped in a Compressed envelope on the SIMULATOR_APP portnum, is delivered through the real receive pipeline (router->enqueueReceivedMessage) as if it arrived off the LoRa chip. It therefore exercises from!=0 enforcement, channel/PKC decryption, remote-admin authorization, and hop/dedup/module dispatch - paths the toRadio API cannot reach (it forces from=0). from==0 is dropped to match real RX. This forges over-the-air traffic, so the flag must never ship enabled. Drive it with the meshtastic-mcp inject_frame tool / cli/meshinject.py. Documents the technique in the agent-facing copilot-instructions.md + AGENTS.md.
Meshtastic Firmware
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
