yes. i tried the inquiries with "hcitool scan".
again, i do 5 and more inquiries in a row with one second sleep between 
inquiries single "hcitool scan"'s...

here what i noted:
- it needs in average 4 inquiries to get a new device after it's in 
rainge (4 single "hcitool scan" until it's visible).
- it needs in average 2 inquiries to see that a device is no longer in 
rainge (or has bluetooth disabled). the first new inquiry usually gives 
"n/a" as the friendlyName, the second one doesn't list it again.
does maybe bluez or my bluetooth dongle cache old inquiries or is there 
still radiation in the air :-) ?

- during scans, if nothin changes (no new/disappeared devices), the 
friendlyName changes to n/a for a single inquiry (very rare, but it happens)

- if multiple new devices come in rainge, old devices migt have a n/a 
friendlyName (the right one comes back in the next scan)


thanks for your time...

kind regards
Marco
