In April 2014, I purchased an HP Spectre 13t-3000 CTO Notebook. Installed is the the Intel Dual Band Wireless-AC 7260 WiFi and Bluetooth adapter.
On HP's support website, the latest driver for the Wireless LAN driver is Version 16.6, 215.11M dated 05NOV2013, and the latest driver for the Bluetooth is Version 1.00, 60.86M dated 01NOV2013. With this driver, I experience intermittent connectivity issues with a Microsoft Wedge Mouse and a Canon ip100 Printer with an installed Bluetooth adapter.
Intel's support website detected an updated driver for both the Wireless LAN and Bluetooh. I updated both drivers to version 17. 1.0.19 and 17.0.1405.0464 respectively.
Unfortunately, I still have the same results. I will print a document over the Bluetooh connection, and it stops responding and only prints a partial page.
I know that the Canon ip100 with Bluetooth adapter is functioning properly because I also have a Microsoft Surface Pro with the same Canon printer driver software installed as on the HP Spectre, and I am able to print through the Bluetooth without any problems.
So, the problem lies within the Intel Bluetooth hardware or drivers on the HP Spectre.
Thank you!
