BV4108 with Arduino UNO

I bought a BV4108 and a 16x2 LCD screen from your store and I tried to make it work on my arduino UNO.
I connected BV4108 tx pin to arduino tx pin and rx in arduino rx pin. +5v to +5v and ground to gnd.
When I power up the arduino the screen shows this:

I tried to insert this code:

#include <BVserial.h>
#include <ASI.h>
#include <bv4108.h>

#define rxPin 0
#define txPin 1
#define dev1 'a'

BV4108 bv(rxPin, txPin);

void setup() {
  bv.baud(9600);
  bv.begin();
}


void loop() {
char b[16];

  bv.cls(dev1); delay(200);

  while(1);
}

but the screen didn't change.

hello,
try phisically swapping the tx and rx round so pin 0 goes to tx on the BV4108 and pin 1 goes to rx on the BV4108

Thank you very much. :) It worked and now I can continue my school project. :D

Has anyone managed to get this display working on an Arduino R3.
If so please explain the method as the web site is confusing

What does it say on the label on to of the IC?
