이슈

  - origin 바뀌는 문제 -> eaglecam 바꿔서 해결. altium은 그냥 잘됨
  - explode all -> 이거 하기는 하는데 뭐하는건지 모르겠네.
  - layer 이름 정리 -> eaglecam 에서 만드는 이름과 altium이름이 다름. 정리하긴 했는데 dimension layer 이름은 를 어떻게 할지 ...

===== BLE OSX App 만들기 =====

상황(Situation): bluetooth 스펙도 잘모르고 Core bluetooth도 써본적이 없고, osx 앱도 만들어 본적이 없다. 대체적으로 모른다. ble 모듈개발을 위해 nordic ble 모듈 펌웨어를 읽은적이 있다.

목적(Task): Core bluetooth에서 discover, connect, and retrieve data 하는 간단한 Bluetooth4.0 어플리케이션 만들기

한일(Action*):
  - 튜토리얼 보고 BLE OSX App을 만들어 본다
  - [[work:bleosxapp_note|연구노트 작성]]
  - 커맨드라인에서 BLE 다루는 테스트 스크립트 만들기http://joost.damad.be/2013/08/experiments-with-bluetooth-low-energy.html 

결과(Result):
  - 1번 Action에 대한 결과:


배운점(Reflection)
