Scan nearby BLE devices, check RSSI signal strength, and view device details.
Scan BLE devices, track RSSI signal strength, compare readings and inspect data.
Scan nearby Bluetooth Low Energy (BLE) devices with a Bluetooth signal analyzer built for RSSI monitoring. Track signal strength in dBm, compare devices, and inspect advertising data in real time. Features: • Scan nearby Bluetooth Low Energy devices. • View RSSI in dBm, signal labels, trends, and a real-time history graph. • Compare two BLE device signals in one session. • Inspect BLE advertisement data, including manufacturer information, service UUIDs, Tx Power, and connectable status when available. • Summarize nearby BLE activity and signal distribution for the current session. • Export current analysis sessions as CSV when you choose to share them. • Use an optional foreground vibration alert, light or dark theme, and multiple app languages. Privacy-focused: • No account, login, ads, analytics, backend server, or cloud processing. • BLE scan results and settings stay on the device during normal use. • No permanent BLE scan history is maintained. CSV files are created only when you explicitly export a current session through Android sharing. Important: RSSI represents relative signal strength. It does not provide exact physical distance or exact device location. Readings can vary because of walls, people, device orientation, antenna design, transmitter power, and radio interference. BLE Signal Analyzer is a diagnostic utility and does not guarantee detection, connection, or compatibility with every Bluetooth device.
