换个粗点的风枪嘴让热风覆盖 RTL8823BS 整体模块最终实现自动归位
焊接 SDIO 接口的上拉电阻以及复位引脚上拉电阻 硬件部分就这么多比较简单接下来是软件部分
打开内核编译选项
搜索 RTL8723BS RTL8723BS 默认关闭不过要使能该驱动之前需要先使能 WLAN 和 CFG80211 搜索 WLAN 使能 WLAN 搜索 CFG80211 已经被打开了应该是使能 WLAN 时将其联动打开了 使能 RTL8723BS 发现只能选择为 [M] 无法选择成 [*]有了解的小伙伴可以告知下原因。我的猜测是WiFi 接口 up 时需要将 fw 文件加载到 WiFi Chip如果将驱动编译成内核静态模块的话驱动初始化在文件系统挂载前那时候还无法从文件系统中读取 fw 文件所以索性就只让该驱动编译成动态模块等操作系统启动完毕后由应用层手动加载这时候就可以方便地从文件目录中读取 fw 文件发送给 WiFi Chip 了。

只有 1Mbps 。。。 哦对了没接天线应该是信号不好看下信号强度 但是板子中并没有 wpa_cli 命令交叉编译了一个 又提示 CONFIG_CTRL_IFACE not defined - wpa_cli disabled 而 wpa_supplicant.conf 中添加 ctrl_interface/var/run/wpa_supplicant 后 wpa_supplicant 又运行不起来。。。 索性不用系统自带的 wpa_supplicant 了应该是有点问题。 按照之前写的一篇文章《hostapd、wpa_supplicant 交叉编译》重新编译 wpa_supplicant 并在 wpa_supplicant.conf 中添加
ctrl_interface/var/run/wpa_supplicant系统重启后查看 RSSI
