Dear all,
由於產品需要RED認證,第三方認證單位提出資安問題.原本我們使用的wifi driver版本為2.4.2.0,在經過對方full port scan後並未發現有任何問題.後續由於連線品質不佳,升版至4.1.1.0.結果被驗出會隨機開啓一個UDP port(50000~65535之間),長時間放置後會關閉,再開啓下一個port.想了解是什麼原因需要自動開啓這個範圍內的port?機器在測試過程中,只有wifi連線(沒有開啓任何的app).
對方的測試環境如下.
Internet <==> Router + HUB <= air connect => DUT ...

謝謝您的回應,使用手冊上只有說有限制命令長度 並未提到內文長度也有限制, 感謝您的說明

Could anyone tell me how to correctly use esp ...
