thank you all for your help i've solved!

haa, i didn't know  .
so it can't work even if i disconnect the usb cable, give to arduino an external psu and push the reset button?

I'll try this code:
#include <SoftwareSerial.h>
#define rxPin 6 // software Rx pin (connect to Tx on LCD)
#define txPin 7 // software Tx pin (connect to Rx on LCD)

// set up a new serial port
SoftwareSerial swSerial =  SoftwareSerial(rxPin, txPin);

void setup()  {
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
  // set the data rate for the SoftwareSerial port
  swSerial.begin(9600);
  // and set the date rate for the real serial port
  Serial.begin(9600);
  delay(100); // (can't use port immediately?)
  startLCD();
  swSerial.print("Hello, world!");
}

void loop() {
   // retransmit bytes read from the computer to LCD
   if (Serial.available() > 0) {
      byte inchar = Serial.read();
      swSerial.print(inchar);
   }
}


void startLCD(){
  
  swSerial.print(0xFE, BYTE);
 swSerial.print(0x53, BYTE);
 swSerial.print(0x75, BYTE);
 swSerial.print(0x72, BYTE);
 swSerial.print(0x65, BYTE);
}

why? don't you like regular serial port?

in my first tests i've connected the lines crossed (tx-->rx and rx<--tx)
but it didn't work
softwareserial? no i didn't use it, can you do an example?

i have the same display you can see in the pictures above, i've soldered a connector to the ttl port, and i've connected tx from the display to arduino pin 1 and rx from the display to the pin 0 of arduino.
when i send something i can see the led blinking on the lcd but nothing more... i'm stuck at the boot screen

could be usefull

hooo, no.. i'm a step behind
i still can't  print :'(
tryed both ttl and rs232 connector i can see the led blink (in one case)but the display doesn't react.
i think because of a wrong inizialization string but i'm unsure...
(same setup same lcd same arduino duemilanove)

what do you mean?? can you make a wiring/communication example? :-/

how did you managed to print characters? it's driving me crazy!

Why anybody cares?

I have the module datasheet:  http://www.adrirobot.it/id_01/moduli/bluetooth/downloads/rbt-001_ds.pdf

And the module user manual: http://www.adrirobot.it/id_01/moduli/bluetooth/downloads/rbt-001_manual.pdf

maybe usefull....

Hi, i have a robotech module called rbt001  and i want to interface it with my arduino duemilanove, the module is rated for 3.3v  , so i think i'll need a level converter.
Can anyone help me to build such interface? i don't know where to start from...
