BluetoothAssistant is an iOS utility designed for users who need deeper insight and control over their Bluetooth connections. For anyone wrestling with intermittent connections, debugging IoT projects, or simply wanting to see what data a connected device is transmitting, this app provides a centralized dashboard. Its primary strength lies in its ability to connect to and log data from multiple BLE devices simultaneously, a feature highlighted by users working with ESP32 microcontrollers. The app displays service characteristics, raw data streams, and connection parameters, which is invaluable for developers prototyping smart home sensors or wearable gadgets. Beyond development, it can help diagnose why a speaker or headset fails to pair by showing the exact handshake process. However, the interface can feel technical for casual users, and some advanced features lack explanatory tooltips. Reviews indicate high satisfaction among hobbyists and professionals who value the granular data access over polished simplicity. For the price, it delivers robust functionality that is otherwise difficult to find in a single mobile package.

"I can connect to multiple BLE ESP32s and see data come in from them all on one central log. At long last. No other goal has been more vital or difficult to uncover."
