What is a BLE UUID?
A BLE UUID, also known as a Bluetooth Low Energy Universally Unique Identifier, is a unique identifier used to define services, characteristics, descriptors, and custom profiles in BLE communication.
UUIDs help Bluetooth devices identify:
- Services
- Device capabilities
- Data types
- Sensor information
- Communication profiles
- Custom commands
Every BLE-enabled device uses UUIDs to organize and exchange information between devices such as smartphones, gateways, embedded systems, and IoT controllers.
Understanding BLE UUID Types
Bluetooth Low Energy supports different UUID formats depending on the application and device requirements.
16-bit UUID
16-bit UUIDs are standardized Bluetooth SIG assigned identifiers commonly used for official BLE services and characteristics.
Example:
0x180D→ Heart Rate Service0x180F→ Battery Service0x2A19→ Battery Level Characteristic
32-bit UUID
32-bit UUIDs provide extended identification space and are less commonly used compared to 16-bit and 128-bit UUIDs.
Example: 0x12345678
128-bit UUID
128-bit UUIDs are custom UUIDs generally used by manufacturers, industrial systems, and private BLE applications.
Example: 550e8400-e29b-41d4-a716-446655440000
Custom UUIDs are commonly used in:
- Industrial IoT devices
- Smart sensors
- Medical equipment
- BLE automation systems
- Proprietary communication protocols
