Title: driver installation instructions Author: Pebbles Subject: RAZER BLADE 15' LATE 2019 - GTX1660 - BASE Realtek audio Control app version 220.127.116.11. Need a Bluetooth Driver for your accessory? If you are having Bluetooth trouble, updates should be available through Microsoft's Windows Update service. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update, or contact the device manufacturer. Update firmware. Open Devices and printersAdd a device (using the mouse in wireless mode if you don't have another mouse). While searching a new bluetooth device switch to bluetooth mode and wait to find it. Use tab and enter from keyboard (or use your other mouse) to select and setup the new bluetooth device.
This section describes the class-of-device (CoD) registry subkeys and entries that apply to the Bluetooth driver stack.

'COD Major' and 'COD Type' Values
Original equipment manufacturer (OEMs) can use the COD Major and COD Type values to indicate the Class of Device for a Bluetooth-enabled Windows device. After the Bluetooth class installer sets the Class of Device based on these registry values, a remote device can determine whether it is connecting to a portable computer, a desktop computer, a phone, and so on.
Select 'Let me Pick from a list of device drivers on my computer' Choose 'HID-compliant game controller' and click 'Next' After the driver is updated, close the window and click 'Yes' to restart your computer.
The registry path to the COD Major and COD Type values is:
Note that setting these values changes the Bluetooth Class of Device for the system, regardless of which Bluetooth radio may be attached. You can set the COD Major and COD Type to
DWORD values as defined for the Class of Device field values in the Bluetooth SIG Assigned Numbers.
The Bluetooth profile driver, BthPort.sys, reads the COD Major and COD Type values to determine how it should respond to a device inquiry. These values affect only the
COD_XXX_MINOR_XXX bits of the Class of Device. The
COD_SERVICE_XXX bits are not affected by this registry entry.
If the COD Major and COD Type values are not set or are set to invalid values, the Bluetooth class installer will set these values to
Scanning Parameterization Settings
Profile drivers can specify scanning parameters settings for their device(s) in their profile driver's INF file to tailor to the specific needs of a given device scenario.
You can override the default system scanning parameters by providing one or more of the following scanning parameters listed below into the AddReg directive. More information on how to use this directive can be found in INF AddReg Directive.
|Value Name||Type||Min Value||Max Value|
|HighDutyCycleScanWindow||DWORD 0x10001||0x0004||0x4000. Shall be equal or smaller than the HighDutyCycleScanInterval parameter|
|LowDutyCycleScanWindow||DWORD 0x10001||0x0004||0x4000. Shall be smaller than the LowDutyCycleScanInterval parameter|
|ConnectionIntervalMin||DWORD 0x10001||0x0006||0x0C80. Shall be smaller or equal to ConnectionIntervalMax|

Changes to scanning parameters make a global impact on the performance of the Bluetooth stack. Making changes to scanning parameters programmatically is not permitted. Using Low Duty Cycle scanning parameters that are too aggressive can not only have a negative impact to the available bandwidth for other Bluetooth Low Energy connections, but also for Bluetooth BR/EDR connections.
