Hi there. Love the library. I noticed there is function to get the battery voltage but cant get it working.

char *batt;
batt=http.readVoltage(voltage);

gets me a void value not ignored as it ought to be how does one use it in order to get battery percentage ?

Hi! Thanks

Try this:


char voltage[64];
http.readVoltage(voltage);
