Comprehensive Online Bluetooth Hardware & Device Diagnostics

The Online Bluetooth Diagnostic Tool enables users to inspect their computer or mobile device Bluetooth hardware using the Web Bluetooth API. Easily discover nearby Bluetooth Low Energy (BLE) peripherals, verify controller driver status, and inspect peripheral attributes directly from the web browser.

Key Diagnostic Capabilities:

Radio Controller Check: validates that your device system Bluetooth controller is powered on and responding to Web API calls.
Peripheral Discovery: scans and pairs with wireless earbuds, headphones, smartwatches, fitness trackers, keyboards, gamepads, and IoT beacons.
GATT Profile Inspection: identifies primary Generic Attribute Profile (GATT) services, including Battery Level Service (0x180F), Device Info (0x180A), and custom data channels.
Connection Latency & Packet Loss Testing: pinpoints intermittent disconnects and range dropouts.

Common Bluetooth Connection Issues:

2.4 GHz Wi-Fi Congestion: Bluetooth shares the crowded 2.4 GHz ISM band with Wi-Fi 4 routers and microwave ovens. High traffic can cause audio stuttering or input lag.
Outdated Controller Drivers: Windows PCs often revert to generic Microsoft Bluetooth drivers which lack advanced LE Audio / GATT feature flags.
Aggressive OS Power Management: mobile and laptop power-saving policies may sleep the Bluetooth module, causing sudden drops.
