Do anyone have the sample code of how to find the ssid name if we didn’t input it all? for example : I want to find the ssid name that start with “Buffalo” and the full name is “Buffalo-xxxx”. How can I write it? ---

can i write it right this? ```auto LE_FATAL_IF(LE_OK == le_wifiClient_Scan(),"SCAN SUCCESSED"); AccessPointRefToConnectTo = le_wifiClient_GetFirstAccessPoint(); if(le_wifiClient_GetSsid(AccessPointRefToConnectTo,ssidd,&ssids) == LE_OK){ p1 = strstr((char*)ssidd,ssidkey); if(p1 == NULL){ for(;;){ AccessPointRefToConnectTo = le_wifiClient_GetFirstAccessPoint(); if(le_wifiClient_GetSsid(AccessPointRefToConnectTo,ssidd,&ssids) == LE_OK){ p1 = strstr((char*)ssidd,ssidkey); if(p1 != NULL){ break; } } } } } ``` ---
