The BCM43242 is not supported here on the Community Website -- it's not a mass-market device. In the documentation, there is mention of a tool called Bluetool. This is a highly proprietary tool from Broadcom, and requires an NDA.
Please reach out to your local Broadcom (now Cypress) Sales organization to get support for BCM43242.
You'll also need ActivePerl-184.108.40.2060 (yes, that specific version).
