Hi all,

I'm new with the bluetooth protocol, but I bought a bt module 2 weeks ago. I started to work on it, i tried to connect it to the arduino and i did it. Now the problem is that I turn it on with Arduino's supply but my bt dongles can't see it.
This is the module:

The datasheet :

says that in the default mode i can detect and see it, but this is not true I can't do it.
I connected:
Module BTM-182   Arduino UNO
PIN 9 Uart_tx    ->  PIN 6 RX
PIN 10 Uart_rx   -> PIN 5 TX
PIN 14 and 16    ->  3.3 V
PIN 15              ->  GND

I also attached three leds: on PIN 22, on PIN 24 and on PIN 28

Its default settings are:

Baud rate : 19200
Data bit: 8
Parity: none
Stop bit: 1

After all this I tried to write on the serial but it answers me strange characters. I can't understand them.

Can you help me please?
Thank you for your attention and your fast replies!
