                 Really great to get a answer ... i think my mobile phone has class 2 bt adapter ... but this issue is a real shock for me ... i thought if any of the devices has a good range , communication channel will be established and data transfer will take place , but all this theory goes in vain .

Can u tell  why this things happen (both the devices should be class 1 ) or where can i look  for the reasons for such a behavior, because i need to inform this to one of my project head and knowing the reason will always help ......

waiting for reply

The "100 metre" range depends on both devices being class 1.  If you
have a class 1 device talking to a class 2 (10m) device, your maximum
range may be higher than 10 metres due to the increased transmit power
and recieve sensitivity, but won't be anything like 100m.

Unlike 802.11 there is no user-adjustable transmit power either,
you're stuck with the dongle figuring that out for you.

If your phone is class1 (a few are, but 99.5% are class2) then you
genuinely have an issue, which could be as simple as a wall in the way
which is blocking the signal, or as difficult as your neighbour having
a leaking microwave oven.
