> > [my description of the inquiry problems with java (jsr82)] > can your reproduce it without using any JSR-82 stuff? 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 ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
