Bluetooth
This low cost module have many functions ...see bluetooth comunication
Is very small and very fragile,here used without adapter...
if you want with adapter ...buy one.
My low cost method is with copper wires,without soldering !
For test ...you need these:
1.Adapter 200v-5v
2.Usb to TTlL Module
3.This bluetooth module
4.1 LED
5.Jumpers wires
Connect bluetooth module with 3.3v from Usb TTL adapter , connect LED between + and Tx pin and power on.
And now you need to pair your bluetooth tranceiver with pc.You may keep in mind what port is
connected to bluetooth module.In my case is port 8.
After this you have need an port monitor for comunicate from pc with bluetooth module.
An easy for use port monitor is AccessPort.exe from http://www.sudt.com
Now send some data a module and you see led blinking!!!
Now try to send some data from an cell phone to bluetooth module...
You should install many bigs programs like Java SDK,Oracle,etc. and you must have programming knowledge...!!!
But is a solution...you can modify bluetooth adress in an existing program like senda.jar(this program is used in my video example).
For this you must have installed Winrar and tiny hexer .
When install Winrar don't forget to allow jar files.
See here how changed bluetooth address in senda.jar file.
Send this modified file ( senda.jar ) to mobile phone...if you mobile phone is compatible led blinking !
That's all ! Now you can send caracter "A" ( via wireless bluetooth with any phone with senda.jar program ) to bluetooth transceiver.
Success!!!
