Good afternoon I'm trying to return more than one value at once via RPC. I have the function set up to return the values I now need to get the value of the requested pin or function and send it back. This code sets up the RPC function then defines it below. I loop through the sepparated strings and want to then return the value of the named pin etc. EG. with the HTTP RPC service if I do {{{"http://mbedip//rpc/returnRPC/run this,is,a,test"}}} I want it to return the values for pins named this, is, a and test <<code>> //Example code not actually in the working version, just for demo purposes DigitalIn this(p19,"this"); DigitalIn is(p20,"is"); DigitalIn a(p21,"a"); DigitalIn test(p22,"test"); <</code>> <<code>> void returnRPC(char * input, char * output); RPCFunction rpcreturnRPC(&returnRPC,"returnRPC"); void returnRPC(char * input, char * output){ char out[255] = ""; char delims[] = ","; char *result = NULL; result = strtok(input, delims); while ( result != NULL ) { strcat(out,result); // Append the results for test purposes. result = strtok ( NULL, delims ); } sprintf(output, "%s", out); } <</code>>

I don't think I made it clear, what I want to achieve is loop through the supplied pinNames and return their values in a formatted string. EG. Enter {{{"HTTP://mbedip/rpc/returnRPC/run led1,p12,led3"}}} in my browser and it returns "1,0,0"
