3. enable iscan and disable pscan:
hcitool cmd 0x03 0x001A 0x01
4. enable both iscan and pscan:
hcitool cmd 0x03 0x001A 0x03
5. inquiry and get inquiry result
5.1 firstly use hcidump -V to get dump information.
5.2 send command to inquiry.

0xB0 0xBD 0xD4 0xE5 0x4C 0x90 means BT address 90:4C:E5:D4:BD:B0, which is obtained from hcidump log.
5.3 as we said, we have already launch hcidump while we execute hcitool command. the below is dump log.
