树莓派4B与Android设备Wifi P2P重连失败问题求助

我尝试使用PBC（虚拟按钮）方法将树莓派4B与搭载Android 14系统的Google Pixel 6设备建立Wi-Fi P2P连接。树莓派重启后首次连接完全正常，但断开设备并删除P2P组（如p2p-wlan0-1）后，再次执行相同连接步骤会出现以下错误：

P2P-GROUP-FORMATION-FAILURE

连接操作步骤 #

• RPI端：通过命令wpa_cli -i p2p-dev-wlan0启动wpa_cli工具
• AD端：Android设备操作

1. AD：进入设置中的Wi-Fi Direct界面，确保设备正在搜索对等节点
2. RPI：执行命令查找并列出对等节点

   p2p_find
   p2p_peers
   

3. RPI：确认找到的设备地址对应目标Android设备

   p2p_peer <device-address>
   

4. AD：点击界面中显示的树莓派设备，使其状态变为“已邀请”
5. RPI：执行连接命令

   p2p_connect <device-address> pbc

首先删除P2P组：

再次执行相同连接步骤后，wpa_cli输出错误：

已确认状态 #

• wpa_supplicant.service已禁用
• wpa_supplicant@wlan0.service已启用

疑问 #

1. 该问题出现的原因是什么？
2. 为何重启树莓派后即可正常连接？
3. 是否存在NetworkManager之类的服务干扰系统？
