Info about String Payload

[adrianmihai83]

I am intrigued by the following thing, I want to send a string to the controller, tried in many things but I don't seem to get one thing. To be short, I want to send to the controller a string containing 14 bytes, more exactly the ID of the RFID Tag. If I am sending this way:

gw.send(msgRfTag.set("24848484852515754685348483"));

everything goes well.

But if I want to do the following:

String strTag = "24848484852515754685348483";
gw.send(msgRfTag.set(strTag));

it does not compile, error: no matching function for call to 'MyMessage::set(String&)'

I use Arduino 1.5.8, on Windows enviroment, latest library.

@adrianmihai83

try using a C string

char *strTag[] = {"24848484852515754685348483"};

that will probably work for you...
