<![CDATA[How to compare single characters of received message?]]>I'm expecting this is just a simple declaration/formatting issue, but I can't work out how to compare the individual characters of a received message.

I want to loop through a received message payload of 20 characters. If I find a "*" character then update a status flag.

          bool status= false;
          for (int i=0;i<20;i++){
            char *a = "*";
            char *b = message.getString()[i];
            if (strcmp(a,b) == 0){
              status = true;
            }
          }

I keep getting a compile error relating to "invalid conversion from char to char* [-fpermissive]".

Thanks

bool status = String(message.getString()).indexOf('*') != -1;
