raspberry-pi - WiFi直接无法将Raspberry Pi连接到Android

Question

我正在尝试通过 WiFi Direct 将 Android 手机连接到 Raspberry Pi，但是当 Pi 是组所有者 (GO) 时，它总是无法形成组。如果我先在 Android 设备上创建一个组，然后让 Pi 加入，它会按预期连接，我可以运行 iperf 来测试连接。

在 Pi 端，我使用 wpa_cli 运行以下命令：

Selected interface 'p2p-dev-wlan0'

Interactive mode

这是日志：

在日志中有一个明显的错误“p2p-wlan0-1：无法连接到内核驱动程序”，但我不知道下一步该去哪里进行调查？
