ESP32 Forum

Sorry, maybe someone has a solution, I have a problem with converting strings to char aray

void stringTochar (String text)
{
char * tx = text.c_str ();
}
If compiled on board uno / nano / promini it can work, but if on board esp8266 / esp32 an error appears. What's the difference between c ++ Arduino and esp. Thank you

It would help if you post the error... for now, I think c_str returns a const char *, so the variable you push it in should have the same type.
