Baseband (BB) Part B Version 1.0B



During our creation, modeling and validation of this protocol, we discovered problems and holes, which we fixed based on our understanding. Below is a list of those assumptions.

  1. The current model has four (4) timer errors that are caused by interaction. No solution has been decided on yet. An example of one of the timer problems is for the Tinquiryscan, which is required every so often. What happens when the BB is in a state like Page Scan when this timer expires? What should be done?
    --Should it save the event and try act on it when current procedures are complete?
    --Should it act on the event then and interrupt the current procedure?
    --Should this even happen?
    --Something else?
  2. Currently the model only models a single device's protocol.
  3. Due to the lack of easily defined interfaces between BB and its other processes (i.e. RF, LMP, L2CAP, and audio), it was necessary to define signals of our own.
  4. Due to the very nature of the BB protocol much of it is implementation dependent, which makes writing an SDL just an exercise and not a standard.
