Not open for further replies.
but it is costly,i want to use Bluetooth SMD Module - Rayson BTM-182 ,i am not satisfy with your answar.
 

All you need to use is to use bluetooth in Serial Port Profile (SSP) Mode,
- Switch your Bluetooth On
- Search it via your Mobile ( your Mobile Should have SPP Facility)
- Connect Module's UART to your PC ( as you are going to communicate with PC; Dont forget to convert 3V TTL to RS232 signal)
- when it is connected it gives a "CONNECT" etc string now with an Application on your mobile using Bluetooth SPP can send data to this
* Your Module should be in Slave Mode ( Does not attempt connect; and Discoverable too)

I have done these things many times if you have any problem tell me
I used LM- Technologies LM400 Module which is 45~50 $ but very easy to use it is plug and play it has a dual Header so SMD soldering is not an issue
