The problem was in my Bluetooth adapter, D-LINK DBT-122 which are said
to support Bluetooth 1.2 but it's not true.
Now, I've tried with some Conceptronic BT 2.0 and it works well. I've
given support for the commands from Bluetooth 1.2:
Write_Inquiry_Mode
Read_Inquiry_Mode
and the reception of Inquiry results with RSSI.
I'd like to collaborate providing the solutions I've found. How can I do
it? Posting my code in this list or sending it to Maksim?
