bitchat is a decentralized, peer-to-peer messaging application that operates over Bluetooth Low Energy (BLE) mesh networks. It provides ephemeral, encrypted communication without relying on internet infrastructure, making it resilient to network outages and censorship. This whitepaper details the technical architecture, protocols, and privacy mechanisms that enable secure, decentralized communication.
It is a 4-inch touchscreen device designed for Meshtastic®, powered by dual MCUs, the ESP32 and RP2040, and supports Wi-Fi, BLE, and LoRa®. It is an open-source, powerful IoT development platform.
Silicon Labs has announced the BG29 family of Bluetooth Low Energy (BLE) wireless microcontrollers, suitable for wearables and even smart teeth implants, featuring an Arm Cortex-M33F core, up to 1MB of flash storage, and a variety of peripherals.
Beacons are Bluetooth Low Energy devices used to deliver proximity-based messages to smart devices. They enhance attendee experience by providing interactive sessions and data tracking, useful for future event planning and sponsor engagement.
