I'm trying to upload the code from here to work with an ESP8266. So I copy/pasted the code to the Arduino IDE and I get this error:
C:\Program Files (x86)\Arduino\libraries\WiFi\src/WiFi.h:79:9: error: initializing argument 1 of 'int WiFiClass::begin(char*, const char*)' [-fpermissive]
int begin(char* ssid, const char *passphrase); ^
exit status 1 invalid conversion from 'const char*' to 'char*' [-fpermissive]
Can anyone help me with this?
This begin() method expects a modifiable character array as its first argument. That's what you should provide:
char ssid[] = "YOUR_SSID"; // this is changed
const char* password = "YOUR_PASSWORD"; // this is fine
[...]
WiFi.begin(ssid, password);
The location where you are calling the function begin, has as first parameter a parameter of type const char* instead of char* ... remove the const from this argument type.
Probably you have something like
const char* s = ....
...
...begin(s, ...)
Change class s to
char* s = ...
