AR1021X使用hostapd配置AP热点注意事项

1、ar1021x使用hostapd配置ap热点注意事项在应用ar1021x模块化集成时，一些应用需要用模块来做soft ap用法，这就牵涉到hostapd配置问题，假如配置不好，是没有ssid热点出来！模块有支持双频的，有只支持单频的，详细要仔细阅读模块规格书,所以配置的时候要留意！普通按照对应的kernel内核版本提供的驱动包，保障物理衔接正常，供电稳定，正常编译驱动后，就能加载胜利，并正常用法！以下案例现象：用法hostapd配置ap热点，ap热点出不来!log信息如下：ostapd -dd -e /dev/urandom /etc/hostapd.conf &random: inv
