BLE Stability Tester

BigIsland

About this app

Stop manually cycling your BLE connections. Automate it.

BLE Stability Tester is the tool every BLE firmware engineer needs. Instead of manually disconnecting and reconnecting your device dozens of times, let the app do it automatically — and give you the numbers that matter.

What it does:
- Scans for nearby BLE devices and lets you pick your target
- Runs up to 500 automated connect/disconnect cycles
- Measures connection latency on every attempt (min / max / avg / P95 / P99)
- Tracks RSSI in real time with a live graph
- Calculates overall pass/fail rate (PASS 95%+, WARNING 90%+, FAIL below 90%)
- Exports results as CSV or JSON for your bug report or spreadsheet

Designed for developers, not consumers:
- No cloud accounts, no ads, no tracking
- Dark mode UI optimized for reading while connected to hardware
- Works with any BLE device — headphones, sensors, medical devices, IoT hardware

Free tier:
- Unlimited scanning
- Up to 3 connection test cycles

Pro (one-time purchase):
- Up to 500 connection cycles
- Full latency statistics (P95, P99, histogram)
- RSSI history graph
- CSV and JSON export
- Full test history
