Venue 11 Pro missing Bluetooth (1537)

Good day,

I'm running W10 and am unable to bet Bluetooth to work.  my unit has the 1537 WiFi and Bluetooth module.  WiFi works well and after installing the 1537 driver the Bluetooth charm will show and light on but Bluetooth does not function. Bluetooth is not showing ad an option that can be turned on or off in the airplane mode section and Bluetooth does not show under device manager.

Please advise. Thank you in advance
