Gleb Shalimov presents esp_ble_finder, a BLE scanning tool designed for the Waveshare ESP32-S3-Touch-AMOLED-1.8 hardware. The application helps users locate nearby devices by monitoring RSSI (Received Signal Strength Indicator) through a visual dotted UI and auditory feedback that mimics parking sensors.
- Uses an AMOLED display to show signal strength with dots and a filling line indicator.
- Features "parking-sensor clicks" where audio speed increases as the user gets closer to the target device.
- Allows users to hunt for specific devices by editing the `TARGET_NAME` in the source code.
- Includes a mute function that silences speaker clicks while maintaining the scan and visual updates.

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.
