Problem with IPAddress (help)
Posted: Thu Aug 17, 2017 8:36 amHello everyone.
I ask the help of my friends for a problem I'm having.
This is an application with NodeMcuonde where it is the client and will connect on a server (C # PC application).
It happens that I have to tell the IP of the server to which the client will connect, and this is placed in the code before void setup ().
Here comes the problem because I will read the eeprom to get the IP address stored there (it can be changed) I get the IP but the IPAdress does not update with the IP value and the module does not connect to the server.
aqui a função para buscar pelo servidor
