+# Meshcore EVO - AOI Edition
 
-## About MeshCore-Evo
+Diese Firmware wurde verändert:
 
-This is a friendly fork of the MeshCore project. 
-Its aim is to provide repeater firmwares with a few additional pending upstream PRs/improvements (i.e. PRs/improvements that are available to the MeshCore project but have not yet been merged in the upstream repo or PRs that might never be merged upstream for some reason).
-These changes are intended to help mitigating challenges in big or dense meshes, e.g.:
+* Modifikation der Sensor-Firmware
+* Gestestet mit Heltec V4
+* Sollte theoretisch mit allen ESP-Boards funktionieren
+* GPIO15 und GPIO16 sind jeweils als Pullup-Eingang definiert.
 
-- Dealing with flood advert traffic
-- improving `denyf *` handling
+### Neue Befehle:
 
-This list might change any time.
-Refer to the [release notes](https://github.com/mattzzw/MeshCore-Evo/releases) for an up-to-date list of the applied changes.
+* "io" gibt den zustand aller 32 GPIO-Pins als Hexcode aus. (Die originale FW gibt eine festcodierte 0 aus.)
+* "bin" gibt den zustand aller 32 GPIO-Pins als Binärcode aus
+* "readpin <pin>" gibt den zustand eines Pins als ON/OFF aus
 
+### Verwendung:
 
+* GPIO 15 oder 16 können z.B. mit einm Schalter oder Relais verbunden werden.
+* Der standardmäßige zustand ist "ON", da intern 3,3V anliegen (Pull-Up Widerstand)
+* Wird ein GPIO nach Masse geschaltet, wechselt der Zustand nach "OFF"
+* Mit "readpin 0" kann als Test der User Button ausgelesen werden.
 
-## About MeshCore
+#### Beispiel:
 
-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.
+Eine laufende Anlage hält ein Überwachungsrelais ständig angezogen, und schaltet GPIO15
+nach Masse. Der Zustand ist daher "OFF" (das könnte als Alarm: OFF gelesen werden).
 
-## 🔍 What is MeshCore?
+Fällt die Stromversorgung der Anlage aus, fällt das Relais ab. Der Zustand von GPIO15
+wechselt daher auf "ON" (das könnte wiederum als Alarm: ON gelesen werden)
 
-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.
+### Hardware:
 
-## ⚡ Key Features
+#### Heltec V4:
+* Firmware kompiliert fehlerfrei und funktioniert
+* Der USR-Button kann mit "readpin 0" gelesen werden
 
-* 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.
-
-## 🎯 What Can You Use MeshCore For?
-
-* Off-Grid Communication: Stay connected even in remote areas.
-* Emergency Response & Disaster Recovery: Set up instant networks where infrastructure is down.
-* Outdoor Activities: Hiking, camping, and adventure racing communication.
-* Tactical & Security Applications: Military, law enforcement, and private security use cases.
-* IoT & Sensor Networks: Collect data from remote sensors and relay it back to a central location.

-## ⚡️ MeshCore Flasher
-
-We have prebuilt firmware ready to flash on supported devices.
-
-- Launch https://meshcore.io/flasher
-- Select a supported device
-- Flash one of the firmware types:
-  - Companion, Repeater or Room Server
-- Once flashing is complete, you can connect with one of the MeshCore clients below.
-
-## 📱 MeshCore Clients
-
-**Companion Firmware**
-
-The companion firmware can be connected to via BLE, USB or WiFi depending on the firmware type you flashed.
-
-- Web: https://app.meshcore.nz
-- Android: https://play.google.com/store/apps/details?id=com.liamcottle.meshcore.android
-- iOS: https://apps.apple.com/us/app/meshcore/id6742354151?platform=iphone
-- NodeJS: https://github.com/liamcottle/meshcore.js
-- Python: https://github.com/fdlamotte/meshcore-cli
-
-**Repeater and Room Server Firmware**
-
-The repeater and room server firmwares can be setup via USB in the web config tool.
-
-- https://config.meshcore.io
-
-They can also be managed via LoRa in the mobile app by using the Remote Management feature.
-
-## 🛠 Hardware Compatibility
-
-MeshCore is designed for devices listed in the [MeshCore Flasher](https://meshcore.io/flasher)
-
-## 📜 License
-
-MeshCore is open-source software released under the MIT License. You are free to use, modify, and distribute it for personal and commercial projects.
-
-## 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.
-
-## Road-Map / To-Do
-
-There are a number of fairly major features in the pipeline, with no particular time-frames attached yet. In very rough chronological order:
-- [X] Companion radio: UI redesign
-- [X] Repeater + Room Server: add ACL's (like Sensor Node has)
-- [X] Standardise Bridge mode for repeaters
-- [ ] Repeater/Bridge: Standardise the Transport Codes for zoning/filtering
-- [X] Core + Repeater: enhanced zero-hop neighbour discovery
-- [ ] Core: round-trip manual path support
-- [ ] Companion + Apps: support for multiple sub-meshes (and 'off-grid' client repeat mode)
-- [ ] Core + Apps: support for LZW message compression
-- [ ] Core: dynamic CR (Coding Rate) for weak vs strong hops
-- [ ] Core: new framework for hosting multiple virtual nodes on one physical device
-- [ ] V2 protocol spec: discussion and consensus around V2 packet protocol, including path hashes, new encryption specs, etc
