i need bluetooth module but i have problem that it is expensive

then how can i implement bluetooth circuit so that i don't need to buy it

and is there any chance to implement it ?

Any suggestions , circuits

Thanks
 

I have used the Bluegiga WT12 which is simple to interface using a UART serial connection

However, as you say, Bluetooth modules are expensive, one reason why we have dropped them from many of our projects and moved to the simpler Microchip MiWi or the Nordic wireless modules.
Is there any particular reason why you have selected Bluetooth? i.e. you have to connect to a Bluetooth device?
 
i need too interface between mobile and microcontroller
but mobile is far from microcontroller by large distance

so i tried to find solution in bluetooth
the data will be sent by mobile is in the inbox simple message
and iwill extract information in the microcontroller

what is a 'large distance' - buletooth has a limited range
what about using a GSM modem where you can send a text message to your mobile phone, e.g.

it is 4 meters
i knew bout GSM module but the using of system will be expensive sms price
in bluetooth there is no money needed when sending data .
 

Bluetooth should have no problem with 4 metres.
A cheaper alternative could be Microchp's MiWi

or Nordic sub 1-GHz RF modules
