Does any body know whether there is a inbuilt bluetooth module inside the 8-bit MCU?
If not can anybody give some details regarding how to interface bluetooth module to 8051?
Bluetooth is a radio-based system, and a processor normally doesn't have any radio-frequency interfaces.
On the other hand, Bluetooth requires a microprocessor for the communication stack.
I would guess that it is more probable that you can find a Bluetooth module with an embedded processor (possibly placed in the same ASIC as the rest of the Bluetooth logic).
"can anybody give some details regarding how to interface bluetooth module to 8051?"
Bluetooth modules are available with many different interfaces; eg, UART, SPI, I2C, parallel port,...
Obviously the details of how to interface this to an 8051 or any other device will depend entirely on which one you choose!
Probably the simplest for a beginner is to start with a Bluetooth module that has a standard RS232 interface. Then it becomes just a standard RS232 project - you can test stuff with hypoterminal, etc...
can u please suggest the device as u said?
Andy can u plz tell me the best suitable modules with UART interface as i am beginner in this?
What are your requirements?
A commercial product?
A private project?
A school assignment?
It is my private project as i just want to learn and explore into bluetooth.
As said by Andy i can try to use Bluetooth with RS 232 interface so that i can connect to the 8-bit controller.
After doing this for example i may use this to detect the mobile phones detection using bluetooth or control some bluetooth enabled device.

...and just search for "Bluetooth RS232 adaptor"
Thank u very much Andy for the info u have given.
