* Add general-purpose packet cache This commit adds a caching system that will save packet data in a much more compact form than the regular MeshPacket protobuf. It cannot be worked with directly to the same degree (although the packet header is available), but consumes *much* less memory, and as a result can be used to temporarily store large numbers of packets. Cached packets can be retrieved either by their (from, id) tuple, or by their hash. This cache is a pre-requisite for the upcoming packet replay feature. * Remove debug initialiser Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Fix ordering Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Add missing size assignment Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Add comments for hash & bucket macros * Make it clear that this field stores a map of the original data --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> Co-authored-by: Ben Meadors <benmmeadors@gmail.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.
