k...as u said that we need to progrm in mc(18F) for communication between bt module and mc.....so in the same way y cant we go for a bt dongle interfacing because of the following reasons:
1.they are cheap and easily available(as already said in edaboard)
the s/w installation of bt drivers is for windows or osx or linux, written for x86 processor not pic microcontroller!!! that's huge difference. Those drivers use whole operating system behind them and only provide "description" for operating system to communicate with the device, everything else is done by the operating system - not by the drivers. There is no way you can use those drivers to drive the usb bt dongle via microcontroller.2.the s/w installation of bt drivers in mc is just around 3KB
this is true, but even if you get any BT to Serial adapter, you do not need to write any code in the device... and as for the "install the s/w cd" .. install where .. you can install that cd on your windoze box, and your bt dongle will work on your windoze box, it will work perfectly, but how does it relates to your microcontroller ?!3.And finally, no need to write any code on our own in the bt dongle again(i.e,it is enough to install the s/w cd which is given by them)
