The Bluetooth LE throughput example in this document demonstrates how link parameters influence the data throughput in Bluetooth LE connections. These link parameters include Connection Interval, Maximum Transmission Unit (MTU), Data Length, PHY, and TX Power. This example can also verify Bluetooth LE data throughput of GR551x SoCs in different transfer modes (Notify, Write, and Notify & Write).

This document introduces how to use a Bluetooth LE throughput example in the GR551x SDK to verify Bluetooth LE data throughput of GR551x SoCs.
