How can I check how many arguments are present in a call ? In a scenario where a variable number of arguments is passed, how can I could the arguments ? (I've noticed that trying to read an argument that isn't there there returns 0.0 for readFloatArg() for example. Is there something I might have missed that already handles argument count ?)\r\n2. I haven't managed to properly use the SendAndReceiveBinaryArguments function. All I could get the sketch to react to was sending a 0;  as binary (0x00 0x3B). I don't think I understood how the binary communication works. Hints ? :)\r\n\r\nThank you,\r\nGeorge"}}
