在应用AR1021X模块化集成时，一些应用需要用模块来做soft ap使用，这就牵涉到hostapd配置问题，如果配置不好，是没有SSID热点出来！模块有支持双频的，有只支持单频的，具体要认真阅读模块规格书,所以配置的时候要留意！ 一般根据对应的Kernel内核版本提供的驱动包，保障物理连接正常，供电稳定，正常编译驱动后，就能加载成功，并正常使用！ 以下案例现象：使用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: Invalid entropy file /dev/urandom random: TryinADDRCONF(NETDEV_UP): wlan0: link is not ready g to read entropy from /dev/random Get randomness: len=20 entropy=0 random: Updated entropy file /dev/urandom (own_pool_ready=0) Configuration file: /etc/hostapd.conf nl80211: interface wlan0 in phy phy0 rfkill: initial event: idx=0 type=1 op=0 soft=0 hard=0 nl80211: Supports Probe Response offload in AP mode nl80211: Disable use_monitor with device_ap_sme since no monitor mode support detected nl80211: Add own interface ifindex 4 nl80211: Set mode ifindex 4 iftype 3 (AP) nl80211: Setup AP -
