Hello Nick, thanks for your quick response..i'm very grateful
The reason why i was converting to String is just because i want to see the data via Serial monitor..hehe
I've tried sending char,
myChannel.sendMsg(tag,sizeof(tag));
but i got these error message
Arduino: 1.0.6 (Windows 7), Board: "Arduino Uno"
TrySendRFID.ino: In function 'void SendingData()':
TrySendRFID:110: error: invalid conversion from 'char*' to 'const byte*'
TrySendRFID:110: error: initializing argument 1 of 'void RS485::sendMsg(const byte*, byte)'
Am i wrong at my structure of programming or something?
Thanks Nick ~
