BLE Peripheral Throughput Test¶

1 功能概述¶

此项目演示从机吞吐率测试,当前版本软件需要nrf connect dongle进行演示。

2 环境要求¶

board: pan107x evb
uart(option): 用来显示串口log（波特率921600，选项8n1）
nrf connect dongle

3 编译和烧录¶

例程位置：<home>\nimble\samples\bluetooth\bleprph_throughput\keil_107x

使用keil进行打开项目进行编译烧录。

4 演示说明¶

烧录完成后，设备会显示上电log，使用pc nrf connect 连接即可。
