Hi everyone.
I have received an array from WiFi in my ESP8266. The array contains this information:
0123-45-67890
This information is saved in an char array named buffer1! and they are ascii codes.
How can I use numbers between any "-"?
This is my code if it helps:
void callback(char* topic, byte* payload, unsigned int length)
{
char buffer1[30];
memcpy(buffer1, payload, length); //copy the payload to the buffer
buffer1[length] = '\0'; //terminate the string (NOT a String !
char * outTopic = "ESP8266Client";
client.publish(outTopic , buffer1);
}
