IBM Integrated Bluetooth III with 56K Modem (BMDC-2)
- 93P3471, 91P7319, 27R1880
This card's Bluetooth controller will work with the standard Linux Bluetooth drivers (btusb) with the BlueZ protocol stack. For the built-in softmodem, have a look at the Conexant HSF modem drivers page for more details.
On recent distributions, you can enable/disable the Bluetooth controller with echo 1 > /sys/devices/platform/thinkpad_acpi/bluetooth_enable if you have the thinkpad_acpi kernel module installed. If you don't, use thecombination instead, as it relies on the embedded controller to work.
There is an issue regarding connectivity with the built-in softmodem, likely due an outdated K56flex firmware. See Need to disable 56K modem speed for a workaround.
