CYW20721 looks like it has what I need but I am having a hard time reading the datasheet. Please answer these questions for this chip:

  1. Is the BT RF antenna built into the chip?
  2. If no antenna then does there need to be an external filter or matching circuit in addition to the antenna?
  3. Can this chip support HSP or HFP bluetooth profiles with the current firmware or custom firmware?
  4. How can this chip be programmed, what is the recommended programming tool?
  5. What is the recommended software development environment for this chip?
  6. Does anyone offer modules with this chip?
