BLE Peripheral ENC

1 功能概述

此项目演示从机ANS服务以及自定义加密特性演示功能，可以配合主机sampleble central演示主从连接，同时也可以配合手机nrf connect演示配对加密功能。

2 环境要求

  • board: pan108x evb

  • uart(option): 用来显示串口log（波特率921600，选项8n1）

  • 手机app nrf connect

3 编译和烧录

例程位置：<home>\nimble\samples\bluetooth\bleprph_enc\keil

使用keil进行打开项目选择需要的controller进行烧录bleprph_enc或者bleprph_enc_spark进行编译烧录。

4 演示说明

  1. 烧录完成后，设备会显示上电log，连接上会显示Connection established,主机订阅完成后输出subscribe event; 。
