Hi, list, As the title, I like to use bssid to specify the wireless networking I want to connect, so if ssid changed, I don't need to change the configure file. Just curious why ssid is a required parameter, it would be nice if only one of ssid and bssid is required instead. -- Regards, Yue Wu Key Laboratory of Modern Chinese Medicines Department of Traditional Chinese Medicine China Pharmaceutical University No.24, Tongjia Xiang Street, Nanjing 210009, China
