The documentation for the example is insufficient. It should say 1) what to do, and 2) what you should expect to see. It would also help if the documentation said what you should see if the bean cannot be detected. And it would help if it said what other tools there are for diagnosing problems with noble. For example, if the problem is with noble, then ble-bean is never going to work. If you give people the tools to show that the problem isn't in this code, you can help them solve the problem rather than trying to get the example to work.
