Copying UdpMulticastHandler's egress guard verbatim capped the BLE mesh at a single hop. A packet that arrived over BLE and comes back through Router::send is a rebroadcast, not a reflection: NextHopRouter::perhapsRebroadcast takes an allocCopy of the received packet, and nothing on the TX path rewrites transport_mechanism - RadioInterface stamps TRANSPORT_LORA in deliverToReceiver, which is only reached on receive. So the copy still said TRANSPORT_BLE_ADV and the guard refused every relay, leaving two nodes able to talk and a three-node chain unable to. Log it and proceed instead. Loop protection is the same as LoRa's and needs no help here: PacketHistory drops a packet seen recently, hop_limit decrements per relay, and onScanReport already ignores frames whose sender is us. Note this leaves BLE without dupe suppression: perhapsCancelDupe is gated on TRANSPORT_LORA, and Router::cancelSending reaches only iface's TX queue, which cannot see BleMeshHandler's ring. Redundant relays are paid for until both are extended. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
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.
