la partie client :
slight_smile: src/main.cpp:72:21: error: ‘httpGETRequest’ was not declared in this scope
temperature = httpGETRequest(serverNameTemp);
Fonctionne trés bien sur Ide Arduino

You trying to write .ino code in a .cpp file without doing the necessary conversion for function prototypes (documentation).
You have to add
String httpGETRequest(const char* serverName);
under const long interval = 5000; .
Alternatively, rename main.cpp → main.ino.
Merci pour l’info, je ferai attention la prochaine fois
