【米尔-全志T536开发板试用体验】Wi-Fi连接测试体验

2025-3-18 11:29:25 1654 嵌入式 Linux

0 开发板效果本节主要介绍Linux 下Wi-Fi 的配置和使用，通常Wi-Fi 模块可以⽀持两种工作模式，分别是STA 模式和AP 模式，有些设备还⽀持STA 和AP 模式同时工作。STA 模式允许设备连接外部Wi-Fi 热点，AP 模式将设备变成Wi-Fi 热点，供其它设备连接。开发板板载AP6256 Wi-Fi 模块。目前版本STA 和AP 模式无法同时正常使用，请等待后续更新。一、SSH服务登录 Xshell 6 (Build 0095) Copyright (c) 2002 NetSarang Computer, Inc.
