okay I though I was done but it looks like I have one more issue with the setting file it when I try and get the unitID it retrieves it in the buffer but does not display it correctly as a byte it is meant to be 1000 no idea how come it is 232
... inside the Loop
Mac Address Print Out = mac=DE:AD:BE:EF:FE:ED
IP Address Print Out = ip=192.168.3.177
Unitid Address Print Out = unitid=1000
Connecting to network
Mac: DE:AD:BE:EF:FE:ED
IP: 192.168.3.177
Unitid: 232
IP Address Set = 192.168.3.177
the only thing I have added was
byte unitid[1] = {0};
else if(strncmp(buffer, "unitid", 6) == 0)
{
Serial.print("Unitid Address Print Out = ");
Serial.println(buffer);
// buffer contains ipvalues
sscanf(buffer, "unitid = %u", &unitid[1]);
}
Serial.print("Unitid: ");
Serial.println( unitid[1]);
Serial.print("Unitid: ");
Serial.println( unitid[1]);
