## About MeshCore
|
||||
## MeshCore Simple Sensor — Heltec T114 + BME280
|
||||
|
||||
MeshCore is a lightweight, portable C++ library that enables multi-hop packet routing for embedded projects using LoRa and other packet radios. It is designed for developers who want to create resilient, decentralized communication networks that work without the internet.
|
||||
Прошивка **Simple Sensor** на базе [MeshCore](https://github.com/meshcore-dev/MeshCore) для платы **Heltec T114** (без экрана) с датчиком **BME280** (температура, влажность, атмосферное давление).
|
||||
|
||||
## 🔍 What is MeshCore?
|
||||
### 🎯 Назначение
|
||||
|
||||
MeshCore now supports a range of LoRa devices, allowing for easy flashing without the need to compile firmware manually. Users can flash a pre-built binary using tools like Adafruit ESPTool and interact with the network through a serial console.
|
||||
MeshCore provides the ability to create wireless mesh networks, similar to Meshtastic and Reticulum but with a focus on lightweight multi-hop packet routing for embedded projects. Unlike Meshtastic, which is tailored for casual LoRa communication, or Reticulum, which offers advanced networking, MeshCore balances simplicity with scalability, making it ideal for custom embedded solutions., where devices (nodes) can communicate over long distances by relaying messages through intermediate nodes. This is especially useful in off-grid, emergency, or tactical situations where traditional communication infrastructure is unavailable.
|
||||
Удалённый сенсорный узел mesh-сети. Автоматически считывает показания с BME280 и передаёт телеметрию в сеть. Поддерживает опрос данных, алерты при выходе за пороги и управление по последовательному порту или через LoRa.
|
||||
|
||||
## ⚡ Key Features
|
||||
### 📻 Параметры радиоканала
|
||||
|
||||
* Multi-Hop Packet Routing
|
||||
* Devices can forward messages across multiple nodes, extending range beyond a single radio's reach.
|
||||
* Supports up to a configurable number of hops to balance network efficiency and prevent excessive traffic.
|
||||
* Nodes use fixed roles where "Companion" nodes are not repeating messages at all to prevent adverse routing paths from being used.
|
||||
* Supports LoRa Radios – Works with Heltec, RAK Wireless, and other LoRa-based hardware.
|
||||
* Decentralized & Resilient – No central server or internet required; the network is self-healing.
|
||||
* Low Power Consumption – Ideal for battery-powered or solar-powered devices.
|
||||
* Simple to Deploy – Pre-built example applications make it easy to get started.

## Contributing
|
||||
|
||||
Please submit PR's using 'dev' as the base branch!
|
||||
For minor changes just submit your PR and we'll try to review it, but for anything more 'impactful' please open an Issue first and start a discussion. Is better to sound out what it is you want to achieve first, and try to come to a consensus on what the best approach is, especially when it impacts the structure or architecture of this codebase.
|
||||
|
||||
Here are some general principals you should try to adhere to:
|
||||
* Keep it simple. Please, don't think like a high-level lang programmer. Think embedded, and keep code concise, without any unnecessary layers.
|
||||
* No dynamic memory allocation, except during setup/begin functions.
|
||||
* Use the same brace and indenting style that's in the core source modules. (A .clang-format is prob going to be added soon, but please do NOT retroactively re-format existing code. This just creates unnecessary diffs that make finding problems harder)
|
||||
|
||||
Help us prioritize! Please react with thumbs-up to issues/PRs you care about most. We look at reaction counts when planning work.

||||
