About bluetooth 2.1

Hi all,
I've read about optimized inquiry in bluetooth 2.1, If I understood correctly the inquiry return remote device name and services list information of the discovered remote devices.
In current version to obtain the same result I've to make an inquiry a name request and a sdp query for every remote device discovered. My question is, given that the new protocol is compatible with the old, if I make an inquiry using a 2.1 dongle with blueZ I don't need to make name and service discovery or it's required because the optimized inquiry works only between devices with 2.1 version?

many thanks
Fabrizio

Hi Fabrizio,

you need to have Bluetooth 2.1 dongles and host stacks supporting 2.1 on both sides to make this work.
