GATTTerm - GATT(BLE) Terminal
GATTTerm is a Windows-based application that allows developers to inspect, simulate, and interact with Bluetooth Low Energy (BLE) devices using the Generic Attribute Profile (GATT).
With support for both GATT Client (Central) and GATT Server (Peripheral) modes, it provides a flexible environment for two-way communication testing and debugging.
Key Features
Dual-Mode Support: Client & Server
- Operates as a GATT Client to connect to BLE devices and explore services and characteristics
- Functions as a GATT Server to simulate a virtual BLE device and accept external connections
Characteristic Operations
- Supports Read, Write, Notify, and Indicate actions
- Toggle between text and binary display formats
- Configure UUIDs, initial values, and descriptions for each characteristic
Device Discovery & Connection Management
- Filter devices by name or UUID
- Connect/disconnect via GUI controls
- View and save connection logs
Service & Characteristic Definition
- Define and edit GATT services and characteristics via GUI
- Save and reuse predefined configurations
Use Cases
- BLE device development, testing, and debugging
- GATT protocol inspection and log analysis
- Simulating peripheral behavior for client-side testing
- Designing and validating custom services and UUID structures
GATTTerm makes the invisible layers of BLE communication visible—offering developers a hands-on, intuitive way to explore, test, and refine GATT interactions in real time.
