Cannot communicate

Hey there,
I am trying to use my arduino BT05 but can't make progress.
I connected;
Vcc to 5v
Gnd to gnd
Txd to tx port 1
Rxd to rx port 0

When I try to connect my phone with BT05 I will get the pop up where I need to fill in the pin (1234). After a while the message "can not communicate" will be seen.

What am I doing wrong?
I am an absolute beginner, sorry.

Thank you in advance

Try connect TX to RX and RX to TX.
