내 안드로이드 휴대폰을 사용하여 라즈베리 파이에서 생성된 무선랜 AP에 액세스할 수 없지만 Windows에서는 작동합니다.

Raspbian이 포함된 Raspberry PI Zero W가 있습니다. 그걸로 WLAN-AP를 만들었습니다. Windows 10 컴퓨터에서는 아무 문제 없이 액세스할 수 있지만 Android 8.1.0 휴대폰에서는 액세스할 수 없습니다. 오류 메시지 없이 짧은 시간(최대 2초) 후에 휴대폰 연결이 중지됩니다.

스캔할 때 AP의 정보입니다.sudo iw dev wlan0 scan

문제는 Android가 일반적으로 Ad-Hoc-Wlan을 지원하지 않는다는 것일 수 있다는 것을 알아냈습니다. 내가 이해할 때"iwlist wlan0 스캔"의 n 모드네, capability: ESS [...]일시적인 것이 아니라는 걸 보여주네요...

sudo iwconfig wlan0전시하다:

wlan0     IEEE 802.11  Mode:Master  Tx-Power=31 dBm
      Retry short limit:7   RTS thr:off   Fragment thr:off

무엇이 잘못되었고 어떻게 해결해야 하는지에 대한 아이디어가 있으신가요?

(PS: DNS 및 DHCP가 Raspberry에 설정되어 작동 중입니다.)
