While the profile may use certain features of the core specification, specific versions of profiles are rarely tied to specific versions of the core specification.For example, there are Hands-Free Profile (HFP) 1.5 implementations using both Bluetooth 2.0 and Bluetooth 1.2 core specifications.

pioneer updating bluetooth connection software-38

Bluetooth capabilities have completely ceased to work on my Acer Iconia w700.

I have recently updated windows 8 and a refresh point did not fix the problem.

Under PC Settings- Wireless, the bluetooth on/off toggle option has COMPLETELY DISSAPPEARED.

On top of this, bluetooth settings on the desktop are also dysfunctional. This video on Youtube discusses how to set up bluetooth, BUT on my computer the bluetooth option under Wifi is gone. I have confirmed by means of using several other devices that have worked before that bluetooth is indeed not working because they are unable to connect.

In order to use Bluetooth technology, a device must be compatible with the subset of Bluetooth profiles necessary to use the desired services.

A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices.

It resides on top of the Bluetooth Core Specification and (optionally) additional protocols.

This table came with an Acer bluetooth keyboard and mouse.

After the upgrade the bluetooth mouse and keyboard were recognized and functioned normally.

I then did a clean reinstall of Windows 10 which was successful but the tablet no longer recognizes the bluetooth keyboard and mouse.

The control panel shows bluetooth is enabled and scanning for devices.
