The GR5xx throughput example in this document demonstrates how link parameters influence the data throughput in Bluetooth Low Energy (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 GR5xx System-on-Chips (SoCs) in different transfer modes (Notify, Write, and Notify & Write).

This document introduces how to use a throughput example in the GR5xx Software Development Kit (SDK) to verify Bluetooth LE data throughput of GR5xx SoCs.

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