Introduction

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 GR55xx SoCs in different transfer modes (Notify, Write, and Notify & Write).

This document introduces how to use a Bluetooth LE throughput example in the GR55xx SDK to verify Bluetooth LE data throughput of GR55xx SoCs.

Before getting started, you can refer to the following documents.
