Bluetooth Analyzer

Bluetooth Analyzer is a practical tool for scanning, analyzing and diagnosing nearby Bluetooth and BLE devices.

The app helps you check real Bluetooth signals, monitor RSSI levels, analyze connection stability, detect weak signals and better understand how Bluetooth devices behave in real-world conditions.

Key features:

• Bluetooth and BLE Scanner
Detect devices near your phone. The list shows available signals, RSSI level, source type and basic device information.

• Measurement Dashboard
Get a quick overview of important data: detected device count, signal quality, current RSSI level and the general condition of your Bluetooth environment.

• Bluetooth Radar
A visual radar helps you observe signal strength and signal distribution. Colored points make it easier to see which devices are closer, farther away, more stable or weaker.

• RSSI Analysis
Track signal strength changes over time. The analysis screen helps you notice RSSI drops, fluctuations, missing readings and unstable device behavior.

• Connection Doctor
The diagnostic module evaluates Bluetooth environment quality, signal stability, surrounding device congestion and issues with the selected device. The app shows a quality score, detected problems and short practical recommendations.

• Selected Device Diagnostics
Choose any signal from the list and check its quality, RSSI, stability and last reading. Problem Detector helps you quickly move to devices that appear weak, unstable or problematic.

• Recommended Tools
The app includes a screen with recommended utility apps, such as WiFi, Internet, battery, temperature, sound, light and magnetic field analyzers.

Bluetooth Analyzer can be useful when you want to:

• check which Bluetooth devices are nearby,
• monitor RSSI signal strength,
• find a weak or unstable signal,
• compare the quality of several devices,
• check whether the Bluetooth environment is crowded,
• diagnose problems with a selected device,
• use radar for easier signal observation,
• get short practical tips to improve readings.

The app can help analyze headphones, smartwatches, fitness bands, sensors, trackers, BLE devices, audio accessories, smart home equipment and other Bluetooth devices visible to your phone.

Bluetooth Analyzer works with real data available from your phone. It does not use simulated measurement results. Data accuracy and availability depend on the device, Android version, system permissions, Bluetooth device visibility and how each device transmits its signal.

The app was designed as a clear diagnostic tool with a dark, high-contrast interface inspired by professional meters. Screens are simple, technical and focused on fast data reading.

Note:
Bluetooth and BLE have limitations that depend on Android and the phone manufacturer. Not every device constantly transmits an RSSI signal, and not every device will be visible in every scanning mode. Results should be treated as diagnostic assistance, not as a laboratory distance measurement.

Recent changes:
Added the PRO Connection Repeatability Test with timed attempts, statistics, GATT error codes, an event log and Bluetooth Expert conclusions. BLE and RSSI scanning, location handling, interface readability and translations were also improved.
