android - Bluetooth Audio gateway problem; system slow to crawl after using serial over Bluetooth -

-

i'm developing application uses bluetooth connection proprietary device. seems work fine, except after while samsung tablet slows absolute crawl , unusable until next forced reboot.

i'm seeing message in alogcat:

e/bluetoothaudiogateway.cpp 2582 pollup detected audio gateway connect notification wrp_find_wsock: no entry found blz_wrapper (2582) btl_if_poll: wsock down, return pollhup pol fd 48, ev 1b

any ideas on going on? seems "bluetooth audio gateway" has bug, can it? i'm not using bluetooth media, how can rid of this, etc.?

thanks!

  1. does speed if disable bluetooth , re-enable it?
  2. how long "a while"?
  3. have verified don't messages if app not running?
  4. have tried app on different device?
  5. does settings...manage applications or battery use screens out indicating if particular process consuming lot of memory and/or cpu?
