Comment 11 for bug 962082

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?
