This is a non-breaking change that increases the internal representation of node counts from uint8_t (max 255) to uint16_t (max 65535) to support larger mesh networks, particularly on ESP32-S3 devices with PSRAM. Changes: - NodeStatus: numOnline, numTotal, lastNumTotal (uint8_t -> uint16_t) - ProtobufModule: numOnlineNodes (uint8_t -> uint16_t) - MapApplet: loop counters changed to size_t for consistency with getNumMeshNodes() - NodeStatus: Fixed log format to use %u for unsigned integers Note: Default class methods keep uint32_t for numOnlineNodes parameter to match the public API and allow flexibility, even though internal node counts use uint16_t (max 65535 nodes). This change does NOT affect protobuf definitions, maintaining wire compatibility with existing clients and devices.
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.
