## What is BLE Scope?

BLE Scope is a lightweight utility for anyone working with Bluetooth Low Energy hardware — firmware developers, integrators, and hobbyists who need to see exactly what a device is broadcasting and talk to it directly.

SCAN
- Real-time scan of nearby BLE peripherals with continuous RSSI updates.
- Per-device RSSI history chart with a moving-average line, so you can watch signal behaviour as you move around.
- Signal-strength grouping and sorting that stays readable while scanning.

INSPECT ADVERTISEMENTS
- Connectable flag, Tx power level, and advertised service UUIDs with well-known names resolved.
- Hex dump of manufacturer-specific and service data, with the company identifier decoded.

GATT
- Connect to a peripheral and discover its services, characteristics, and descriptors.
- Read characteristic values, with decoders for well-known characteristics.
- Subscribe to notifications and indications with a rolling value log.
- Write values as hex or text, with or without response.

FAVORITES
- Mark the peripherals you care about; favorites are stored on device and persist across sessions.

BLE Scope has no account, makes no network connections, shows no ads, and collects no data. Scanning and connections run only while the app is in the foreground.
