[Bug 962082] Re: Profiles that require duplex audio like Head Set (HSP) and Hands Free (HFP) do not work on machines with Broadcom BCM20702A0 Bluetooth chips

[James Anderson]

Forgive what seems like a silly question, but I have a Dell Precision
M4700 with the BCM20702A0 Bluetooth adapter.  From what I can gather of
the linked bug, the ability to load the firmware now works, but I cannot
find any clear instructions on how to load the latest firmware, nor
where I can get the latest firmware.  I've read about getting the hex
files from the windows driver, but I can only find an exe file on the
Dell site for Bluetooth sofware.

Can anyone help?
