This library provides a development framework for managing Bluetooth Low Energy connections and data exchange on Android devices. It functions as both a client manager for executing read and write operations with hardware peripherals and a server framework for configuring local devices to host GATT services. The library distinguishes itself through a managed, queue-based architecture that serializes asynchronous requests to prevent command collisions and ensure reliable transmission. It automates complex tasks such as packet splitting, service discovery, and connection retries, while maintain

BitChat Android is a decentralized peer-to-peer messenger that enables communication over Bluetooth mesh networks without requiring any internet connection or central servers. It functions as a full mesh network chat app and a privacy-focused communication tool, with every message encrypted end-to-end using per-session cryptographic keys that ensure forward secrecy. The app operates without accounts or persistent identifiers, resisting user tracking at the protocol level. To strengthen privacy and efficiency, BitChat injects cover traffic to obscure real communication patterns and includes an

This library is a framework for Android applications to manage Bluetooth Low Energy connectivity, peripheral discovery, and data exchange. It provides a standardized interface for integrating wireless hardware, enabling developers to handle complex communication tasks through a structured connectivity framework.
