ESP8266 Community Forum

- Sat Oct 02, 2021 10:31 am #92516 Hi,
I wrote simple function to manage WiFi connection of my ESP8266.
Im read data from INI and I would like set wWiFi according INI setup.
I have this proble, IF I join to ESP AP Network work only with static IP (automatic IP assignement don't work).
As ESP client if I try to disconnect from one network and connetct to another cannection fail (return value 7). Any idea to help ?

Code: Select allvoid WiFiConnect(const char* filename)
{
  IPAddress mask;

  if(ini_open (filename))
  { 
    NetworkChoice = ini_read ("NetworkChoice", "network","0");
    ClientSSID = ini_read ("network" + NetworkChoice , "ClientSSID","BuddaceCasa");
    ClientPassword = ini_read ("network" + NetworkChoice , "ClientPassword","25399750057853538077");
    ClientSSID0 = ini_read ("network0", "ClientSSID","BuddaceCasa");
    ClientPassword0 = ini_read ("network0", "ClientPassword","25399750057853538077");
    ClientSSID1 = ini_read ("network1", "ClientSSID","BuddaceCasa");
    ClientPassword1 = ini_read ("network1", "ClientPassword","25399750057853538077");
    ClientSSID2 = ini_read ("network2", "ClientSSID","BuddaceCasa");
    ClientPassword2 = ini_read ("network2", "ClientPassword","25399750057853538077");
    HostSSID = ini_read ("host", "HostSSID","CV19Archimede");
    HostPassword = ini_read ("host", "HostPassword","PlasticoCV19");
    HostIp = ini_read ("host", "HostIp","10.10.0.1");
    HostSubnetMask = ini_read ("host", "HostSubnetMask","255.0.0.0");
    ini_close();
  }
  else

    NetworkChoice = "0";
