* Only send Neighbours if we have some to send. The original intent of NeighborInfo was that when a NeighbourInfo was sent all of the nodes that saw it would reply with NeighbourInfo. So, NeighbourInfo was sent even if there were no hop-zero nodes in the NodeDB. Since 2023, when this was implemented, our understanding of running city-wide meshes has improved substantially. We have taken steps to reduce the impact of NeighborInfo over LoRa. This change aligns with those ideas: we will now only send NeighborInfo if we have some neighbors to contribute. The impact of this change is that a node must first see another directly connected node in another packet type before NeighborInfo is sent. This means that a node with no neighbors is no longer able to trigger other nodes to broadcast NeighborInfo. It will, however, receive the regular periodic broadcast of NeighborInfo, and will be able to send NeighborInfo if it has at least 1 neighbor. * Include all the things * AvOid memleak |

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.
