T61 bluetooth(BCM2045B) drivers

#1 Post by donli » Mon Dec 09, 2019 12:58 am

Wondering what is the proper Bluetooth driver set for T61 BCM2045B win10 build 1909 that not requires further installation (device manager, driver properties, events) and works with audio headset?

BCM2045B is Bluetooth 2.1+EDT radio device.

Broadcom 12.0.0.4051 driver can fit best for relevant headphones I guess.

Otherwise only pairing occurs, no sound.

It is difficult to find direct download webside

Solution to avoid error and warning events in system event board, win10.
Disconnect built-in Bluetooth radio device,
switch off security processor from bios,
disable biometrics driver using device manager
