Extend Android Bluetooth Discoverability -


i writing application relies on android device (for current testing purposes htc evo 4g , several original motorola droids) being discoverable via bluetooth 300 seconds.

i targeting android version 2.0.1, according api should able prompt user enable discoverability maximum of 300 seconds. on both droids , evo prompt window has 300 seconds listed, both end after 120 seconds.

the code used prompt user here:

private void makediscoverable() {     intent discoverableintent = new intent(             bluetoothadapter.action_request_discoverable);     discoverableintent.putextra(             bluetoothadapter.extra_discoverable_duration, 300);     startactivity(discoverableintent); }

i code runs. however, later have handler when discoverability status changes (in case ends, assume) reads this:

if (isdiscoverablechange(action)) {             int discoverstate = intent.getintextra(                     bluetoothadapter.extra_scan_mode, short.min_value);             if (isdiscoverablestate(discoverstate)) {                 setitorder();                 setupscananddisplay();             } else {                 discoverscheduler.cancel();                 itscheduler.cancel();             }         }  private boolean isdiscoverablechange(string action) {     return bluetoothadapter.action_scan_mode_changed.equals(action); }  private boolean isdiscoverablestate(int state) {     return state == bluetoothadapter.scan_mode_connectable_discoverable; }

i tried commenting out portion runs when discoverability mode ends, in case cancelling prematurely, discoverability end after 120 seconds.

is hardware issue, or doing wrong here?

it appears bug:

issue 15486: bluetooth adapter.extra discoverable not obeyed http://code.google.com/p/android/issues/detail?id=15486

issue 13361: bluetoothadapter.extra_discoverable_duration intent not extend 120 sec discovery interval http://code.google.com/p/android/issues/detail?id=13361

first reported dec 22, 2010, still listed 'new' status, wouldn't expect fixed.
