GATT Throughput Service
The GATT Throughput Service is a custom service that receives and writes data and returns metrics about these operations.
To test GATT throughput, the client (central) writes without response to the characteristic on the server (peripheral). The client can then read the characteristic to retrieve the metrics.
The GATT Throughput Service is used in the Bluetooth: Throughput sample.
Service UUID
The 128-bit service UUID is 0483DADD-6C9D-6CA9-5D41-03AD4FFF4ABB.
Characteristics
This service has one characteristic.
Throughput (0x1524)
- Write Without Response
Write any data to the characteristic to measure throughput.
Write one byte to the characteristic to reset the metrics.
- Read
The read operation returns 3*4 bytes (12 bytes) that contain the metrics:
Four bytes unsigned: Number of GATT writes received
Four bytes unsigned: Total bytes received
Four bytes unsigned: Throughput in bits per second
