TransparentBLE is a local-first Bluetooth Low Energy utility for discovering, inspecting, logging, and controlling BLE devices from iPhone or iPad.
Use it to scan nearby BLE peripherals, connect to devices, inspect GATT services and characteristics, read values, write payloads, subscribe to notifications, and debug raw BLE traffic in console and terminal-style views.
TransparentBLE also supports reusable BLE profile files. A profile can describe how a device should be matched, which services and characteristics it uses, how notification payloads should be parsed, and which controls should appear in the app. This lets makers, developers, and hardware owners create an iOS control surface for BLE devices without building a custom Swift app.
Features:
- BLE device scanning with configurable refresh intervals
- GATT service and characteristic inspection
- Read, write, and notify support
- Console and terminal-style BLE debugging
- RSSI tracking and RSSI history graph
- JSONL diagnostic log recording
- Log history with filtering, timeline view, export, and share support
- Optional background recording for diagnostics
- Live Activity and Dynamic Island status while recording
- Import local .bleprofile.json files
- Import profiles from supported TransparentBLE links
- Profile-based controls including switches, sliders, RGB controls, and option pickers
- Local-first design with no ads, analytics, tracking SDKs, or developer-operated cloud service
TransparentBLE is useful for BLE debugging, hardware testing, IoT projects, ESP32 experiments, embedded devices, meters, sensors, chargers, and custom BLE hardware where you understand the device protocol.
Safety note: BLE profiles and write commands can affect connected hardware. Only import profiles you understand and trust, and test control commands carefully.
