I have installed the Broadcom stack onto my Win8.1 desktop. I’d like to use the PC as a hands-free device. Is there something special I need to do to expose the profile to my phone? A2DP shows up, but not HFP.

I want to use my PC as a hands-free device with my phone. I’d like the audio to come out of my PC speakers and use the PC microphone.

Hey Brandon,
I spent the last half hour or so trying to get this to work on several different phones, and had no luck. I see your frustration!
It looks like for some reason support for this has been dropped by Broadcom, and I’m not sure why. I was able to do this when we initially released the adapter with Windows 8.
I tried this with Broadcom software versions 6900 and the latest, 9820. Neither had any success. The confusing part is that the HFP service is active and running (you can check this by right clicking on the phone in Device sand Printers, selecting Properties, then going to the Services tab).
Another odd clue is that if I go in to the sound control panel, Bluetooth Hands-free Audio is a device under both Playback and Recording, but if I right click and click connect, nothing happens.
I’ll keep working on this and see if I can come up with a solution, and also submit a ticket to Broadcom and see if I can figure out what happened. This didn’t used to be difficult, and was all done previously in that device control panel.
Let me know if you are able to make any headway either.

Thanks, Sam! I’m glad it wasn’t me…
I came across this service in some research…
BthHFEnum service ?
see here: http://batcmd.com/windows/8/services/…
C:\Windows\System32\drivers>sc start BthHFEnum
[SC] StartService FAILED 1058:
The service cannot be started, either because it is disabled or because it has n
o enabled devices associated with it.
I don’t know much about drivers and what not, but this seems to something tied to it. Perhaps the driver has to implement something so that the service is associated to the device so that it can subsequently start?
This link:
http://msdn.microsoft.com/en-us/libra…
describes the service as:
This module provides drivers for the Bluetooth Hands-Free Audio and Call Control HID Enumerator.
Not sure if it’s related. Hopefully it can be resolved!
Hey Brandon,
After some more testing, I think that this just may not be possible. Not only can I not get this to work with our adapter, I can’t get it to work with *any* adapter. It looks like it might be a disabled feature in Windows now.
The BthHFEnum service is a demand start services and it isn’t listed in the normal services list (services.msc). From the description, it looks like this service is called by another service when a Bluetooth HID device needs to be enumerated.
I’ve yet to get any word from Broadcom. From my testing, I think this is most likely going to be a no go, though. If you’d like a refund for the adapter, I’m happy to help with that process if you contact me through support@plugable.com
Let me know if you have any thoughts or concerns.
Best wishes,
