I m not able to send data by bluetooth from my xperia 8 can u help me out from this problem

Usually the procedure to be followed is to select the file and from its options choose to send or transfer ..and select more options and the way to be transferred..In some devices this options is not called transfer or send ..but its called copy ..to ..or by ..After all these..you will be guided to the find device options and the device you want to copy to must be bluetooth activated and you will be able to select it from the list of devices found....by its name ...In this point you will be asked for the security code...wich is usually 0000 or 1234 if never been changed..and the transfer will begin after you confirm the transfer from the second device (the one receiving )
Another way is to activate the bluetooth in both devices...and in the one you want to send the file to ...activate it for to be found..(it has this option in the bluetooth feature..) after hat when the devices are paired..just select the file and send it by ..choose bluetooth and from the list choose the device by its name ..and click send ..after which you will have to confirm the transfer from the device you'll send to ..
