全能小网关|CH32V208--第五篇：ETH与BLE的联动
<div class='showpostmsg'> 本帖最后由 xiaolinen 于 2024-7-20 19:07 编辑<p><span style="font-size:22px;"><strong>一：说明</strong></span></p>
<p><span style="font-size:20px;"> （1）本次实验是在BLE_UART例程中，添加TCP客户端和SLEEP功能下进行的；</span></p>
<p><span style="font-size:20px;"> （2）ETH和BLE共存的情况下，将系统核心时钟设置为120MHz：</span></p>
<p><span style="font-size:20px;"> 既：uint32_t SystemCoreClock=SYSCLK_FREQ_120MHz_HSE; </span></p>
<p> </p>
<p><strong><span style="font-size:22px;">二：设置SLEEP功能</span></strong></p>
<p><span style="font-size:20px;"> 2.1，sleep功能进入逻辑</span></p>
<p><span style="font-size:20px;"> 当蓝牙接收到“AT+SLEEP=1\r\n”时，进入低功耗模式；</span></p>
<p><span style="font-size:20px;"> 2.2，sleep功能使能和低功耗模式下GPIO的状态设置函数</span></p>

蓝牙转wlan，确实是比较牛的功能了。
<p>因为工作需要用到这个转换，也算是提前熟悉这部分功能了。</p>
