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:http://www.sparkfun.com/products/9913
The datasheet :http://www.sparkfun.com/datasheets/Wireless/Bluetooth/BTM182.pdf
says that in the default mode i can detect and see it, but this is not true I can't do it.
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
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!
