- Cocoa run_loop: added timeouts, include in libBTstack.dylib build
2010-xxxx: Release 0.2 - revions xxx
- limit size of /tmp/hci_dump.pklg to 1000 packets (max 1 MB)
- power handling: receive power notifications
- power handling: handle power changes in all states, receive and handle power notifications
NEXT:
- power handling
- DONE: figure out how to receive iPhone System Power IONotifications (in BTdaemon) to detect, when phone gets locked and wakes up
